IEM Buyers Guide: Universal & Custom In-Ear Monitors

CAYLA MENGES | MOON AUDIO STAFF/

Everything You Need to Know to Find Your Perfect Pair of IEMs

Ask any child whether they want the small wrapped gift or the big one, and they'll undoubtedly choose the big gift. Ask any audiophile or music lover whether they want full-size headphones or IEMs, and the answer isn't as certain. For some people, full-size headphones are a must-have. For others, the smaller option–IEMs–will be the right choice. And many people will choose both!

The audiophile community is full of over-ear headphones but they're not always the most portable, practical option for everyday listening. Thus enters In-Ear Monitors (commonly referred to as IEMs), the earbuds of the audiophile community. While they're not wireless like Apple AirPods, they offer far more in terms of sound quality and technology. And yes, wired earphones/earbuds may seem like a thing of the past, but us audiophiles know that a wired connection is far superior than a wireless. Great for working out, commuting, running errands, and just about every activity in between, IEMs are a great solution for someone seeking a convenient listening option without sacrificing sound quality.

So whether you're a first-time IEM buyer, a seasoned veteran, or just someone curious to learn more, discover the allure of IEMs and why they're one of the most coveted treasures in the audiophile community. Choose from universal and custom fits, multiple driver configurations, and learn why the perfect seal is essential to a great listening experience–all right here.

Why Choose IEMs?

If this is your first time buying IEMs you might be asking yourself "Why would I buy something that costs the same, if not more, than a full-sized pair of headphones but is half the size?" and that's a great question. IEMs aren't going to be everyone's cup of tea but for those seeking a portable, discrete option, they're perfect. No bigger than a silver dollar coin and weighing far less than a pair of full-size cans, IEMs are a convenient way to enjoy music. Because of their small size, they're effortlessly portable and when paired with a hi-fi DAP (Digital Audio Player), or your phone and a portable DAC/headphone amp, your IEMs make for a great on-the-go or home listening solution. When coiled up they'll fit neatly inside of a travel case that's smaller than a wallet. They'll even fit in your pocket (but we wouldn't recommend that). 

  • Small
  • Portable
  • Intimate Listening Experience
  • Options for Customization

You might not have realized that your favorite singers, guitarists, and musicians have been using IEMs on stage for years. Yep, those aren't earplugs in their ears! They were honestly probably one of the best kept secrets in the music industry up until audiophiles discovered them. Audio engineers use them for live monitoring and studio production (sometimes rivaling the sound of high-quality studio monitors), and they allow musicians to hear themselves and their personal mix while blocking out competing vocals and sounds. As IEMs have become more and more sophisticated (think multiple driver IEMs and advanced technology), they have become more and more popular among audiophiles. Nowadays, IEMs are used by audiophiles, musicians, audio pros, and music lovers alike.

IEMs range in price from budget-friendly models to high-end and the collection of choices is endless. Not to mention they come in two variations, custom and universal, which we'll get right into.

IEMs vs. Earbuds: What's the Difference?

IEMs, earbuds, and earphones–aren't they all the same? To put it simply, no. IEMs and earphones are two phrases used interchangeably in the audiophile community, but they are not the same. At first glance, it's easy to mistake IEMs and earbuds for the same thing, but there are a few clear differences.

1. Fit: Earbuds sit on the outer structure of the ear, while IEMs sit inside of the ear canal

2. Seal/Noise Isolation: IEMs create a seal in the ear, giving a more secure fit and better noise isolation. When you block more sound, you don't have to turn the volume up as high, making IEMs better for hearing preservation. You also get a more immersive listening experience from IEMs vs. earbuds.

3. Driver Configuration/Technology: Earbuds mainly use a single dynamic driver or sometimes a balanced armature driver, while IEMs can use a variety of driver types, either single or multiple, and alone or in combination. IEMs are also going to feature more advanced technologies than most earbuds.

These differences may seem minor, but mistaking one for the other when buying IEMs could lead to a road of disappointment if you intended to buy IEMs. When you think of earbuds, think of Apple AirPods, Beats Solo–the more readily available, consumer-grade earbuds. When you think of IEMs, think JH Audio, Empire Ears, Shure–hi-fi market, audiophile-grade IEMs.

The Right IEM for You: Universal vs. Custom

Unlike headphones, which are generally one-size-fits-all, most IEMs come in two fit types–Universal and Custom. Universal-fit IEMs (UIEMs) are the most common type, made to fit a broad range of ear canals. Most people have no problem fitting and wearing universal IEMs comfortably, but it depends on the shape of the IEM and the size of your ear canal. Custom In-Ear Monitors (CIEMs) are one-of-a-kind designed for your ears and yours only. How? Using a custom mold of your ear canal! Most IEM manufacturers make universal IEMs, but there are some brands like Empire Ears and 64 Audio that offer custom IEMs.

Universal IEMs

Empire Ears ODIN Universal IEMs

Universal IEMs can be a good, ready-to-go option for many listeners. They are designed to fit most ear canals, meaning you can be reasonably sure they will be comfortable for you while providing a good seal. They usually come with ear tips in various sizes so you can find the most secure and comfortable fit. If you don’t want to get ear impressions or wait for custom IEMs to be built, universals are the way to go. Universal IEMs are typically less expensive than custom-fit models too. This is the easiest type of IEM to come by, with almost all manufacturers offering universal-fit IEMs.

Another consideration is degree of noise isolation. If you will be using your IEMs in an office or other environments where you need some awareness of outside sound, universals will provide that because they don't provide as tight a seal as custom-fit IEMs. But if you plan to use IEMs when working out, running, or performing on-stage, you'll want the snugness and security of custom IEMs.

Finally, universal IEMs can be resold to another user. Unless you have a twin—and even then there'd be slim chances your ear canals are the same—there's no way you can resale a pair of custom IEMs.

Custom IEMs

Performing artists and audio professionals who desire maximum fit and better sound isolation usually opt for custom IEMs, but they've grown incredibly popular among audiophiles seeking the utmost comfort and personalization. The list of manufacturers producing custom IEMs is slimmer, but two brands we carry–Empire Ears and 64 Audio–offer custom models. Each pair of custom IEMs is specifically molded for the user's ear canal shape using an impression obtained by an audiologist. Because of the need for a custom impression, custom IEMs are more expensive than universal and take longer to arrive at your doorstep.

One of CIEM's biggest draws is the level of noise isolation a custom-fit delivers. The better noise isolation of custom IEMs means you can listen to them at a lower volume, which helps to protect your hearing. Custom IEMs are also a good choice for use while exercising (running, in particular!) or other activities in which you don't want to worry about an earpiece slipping out. With a CIEM, you get a better seal and a personalized fit with no need for silicone or foam ear tips. You also get a perfect fit for each ear, which is useful if your ear canals are not symmetrical (it's not uncommon).

Custom IEMs also allow you to achieve a particular aesthetic. Empire Ears offers many ways to customize the look of an IEM. Shells and faceplates are available in a variety of opaque and translucent colors. There are also premium and signature designs available for the faceplate, and you can choose from a variety of logos, or even your custom artwork (depending on manufacturer). For those looking for the utmost in fit and comfort, custom fit IEMs are the way to go.

How to Order Custom IEMs

Interested in ordering custom IEMs? Check out the guide to Custom IEMs and place your order today.

Custom IEM in 3 Steps

1. Choose your Custom IEM

We offer custom IEMs from the renowned IEM manufacturers Empire Ears and 64 Audio. Selecting which custom IEM you'd like is no different than picking a universal IEM. You want to pick the IEM that delivers your desired sound.

When you have chosen the IEMs you like, go ahead and place your order at moon-audio.com. After that, you will need to obtain your impressions.

2. Get an Ear Impression

After you've placed your order, it's time to obtain your impressions. Please follow an IEM impression guide to ensure the best possible fit for your custom IEMs. Remember that your ear impressions will dictate the final fit of your custom IEMs.

  1. Find an Audiologist in your area (Googling an audiologist in your city will provide a list). Make sure you find an audiologist familiar with how to make a "full shell impression including the crus of helix, tragus, and anti-tragus"— that's audiologist speak, they will understand. Molds should cost anywhere from $50 to $150 depending on where you live.
  2. Once you've received your molds, email impression photos to sales@moon-audio.com for approval. Take a few photos of your impressions with your phone on a solid color surface and background. Please make sure there is adequate light to provide us with the most detail possible. Please include your full name and allow us 24 hours to review your impressions.
  3. After you've received approval for your molds via email, it's time to mail your impressions to Moon Audio. Complete this form with your name, order number, email, phone, and address and mail it with your impressions to:

Moon Audio

1157 Executive Cir. Suite 101

Cary, NC 27511

3. Await a Music Experience Like No Other

It normally takes 4-6 weeks for you to receive your custom IEMs, but trust us, it's worth the wait. When you order your custom IEMs from Moon Audio, you can also choose to upgrade the stock IEM cable to one of our Dragon Audio IEM Cables.

The Importance of Proper IEM Fit

Fit is essential to the perfect IEM listening experience. If one or both earpieces (nozzle with ear tips attached) do not fit snugly enough, they may slip, forcing you to reach up and readjust. There is also the issue of comfort, as an improper fit just won't feel good in or on your ear. No one wants to spend their hard-earned money on a new pair of IEMs just to find out they're so uncomfortable they'll never wear them. To ensure you are getting the best fit from your IEMs, make sure you are inserting them properly. With universal IEMs, be sure to secure the tip onto each earpiece. If using Final Audio Type E tips, squeeze them before insertion.

The other major consideration is sound quality. Without the proper seal, you won't reap the full sonic benefits of your IEMs and what's supposed to sound great might end up sounding horrible. You'll be asking yourself "Why do these $1,500 IEMs sound like $20 earbuds?" If your IEM earpieces are not properly positioned within your outer ear canal, your audio will sound sub-par with lower volume and diminish the low-end response. There will also be less noise isolation. To help ensure this doesn't happen, you may need to experiment with ear tip styles and sizes. Silicone and foam ear tips are the top two ear tip types and most often your IEMs will come with silicone tips in up to 5 sizes (SS, S, M, L, XL).

To Insert Your IEMs

IEM Cable terminations

1. Match the correct IEM with each ear (you'll find a color indicator or L/R symbol for the left or right IEM)

IEM insertion guide graphic

2. With each earpiece (nozzle) resting loosely at the base of your ear canal, turn the IEM forward, then gently insert it into your ear canal.

IEM insertion guide graphic

3. Gently rock it back and forth, until completely snug in the ear

IEM insertion guide graphic

4. With the cable facing in an upward direction, secure it behind the ear by pulling it up and over the top of your ear

IEM insertion guide graphic

5. Cinch the IEM cable for the best isolation

Tips

  • You may hear a slight 'pop' or suction sound indicating you've achieved the proper seal. This does not happen with every IEM, it is completely normal and is a phenomenon found most with dynamic driver IEMs.
  • If the IEM is not snug, falling out, or too big for your ear canal, switch out ear tip sizes (sizing down for too big and up for too small). Try different ear tip types if you still cannot achieve a proper seal.
  • Gently wiggle your ear lobe and/or slightly open your mouth to expand your ear canal ever so slightly to achieve a snug fit.

Attaching and Detaching Your IEM Cable

1. Attach: Match the correct IEM with the right cable. The cable and IEM will have a color indicator or L/R to denote which

2. With the top of the connector facing upward, insert the IEM cable by sliding it into the socket of the IEM until it feels snug. There may be a colored dot or arrow on the cable indicating the top of the connector. This indicates that the positive and negative are inserted correctly.

3. Detach: Grasp the base of the cable by its port and gently pull outward while wiggling back and forth ever so slightly. DO NOT attempt to remove by puling the cable or you might damage the cable port and IEM.

Caring For Your IEMs

Have you ever taken out your earbuds only to discover your ears weren't as clean as you thought? We've all been there and the funny thing about ears is that no matter how often you clean your ears, there's always a tiny bit of earwax that somehow gets missed. Well, your IEMs are like magnets for the tiny dirt and grime that lurks in the crevices of your ears and if you're not careful you can wind up with a mound of build-up damaging your IEMs tech and performance. This is not covered under warranty. You'll want to routinely clean your IEMs–ideally after every use–so you can mitigate that buildup and prevent any damage to your precious in-ear monitors.

Most IEMs come with an included carrying case (usually hardshell) for storage and protection, several ear tips, and a stock cable. Occasionally, you'll find accessories like a cleaning tool and microfiber cloth. In the cases where you're buying your IEMs secondhand or you don't get all the additional swag, here are our recommendations for IEM care.

DO

- Clean the exterior, interior, and underside of ear tips with alcohol wipes

- Use a microfiber cloth to polish the shell

- Use the brush end of a cleaning tool to eliminate any debris on the surface of your IEMs

- Use a cable removal tool to properly detach the cable. If you do not have a removal tool, grasp the base of the cable where it meets the IEM and gently pull the attached connector

- Coil up the cable using the over-under method, following the natural shape the cable bends

- ALWAYS store IEMs in a carrying case

DO NOT

- Clean your IEMs with the cable and ear tips attached

- Use abrasive cleaning agents to polish the shell

- Scrub the IEM nozzle using brut force

- Expose your IEMs to moisture

- Remove your IEMs by pulling on the cable

- Wear an IEM if it has microfractures, as it can break during use

- Allow the IEM to hit hard surfaces or knock into each other

The Anatomy of an IEM

Like headphones, IEMs come in all shapes and sizes. Some manufacturers, like Empire Ears and 64 Audio have a signature look, with the only thing changing between launches being the faceplate color. Others "break the mold" sort of speak and create less traditional, more unconventional-shaped IEMs. But shape is just one aspect of an IEM's anatomy. You've also got all of the technology inside of IEM that impacts its sound quality and listening experience. Let's dive into the anatomy of an IEM so you can make the most informed buying decision on your IEM journey.

IEM anatomy diagram

Shell

The Shell is the outermost part of the IEM. It can also be referred to as housing. It's the protective housing of the IEM that contains the IEM drivers and additional tech. Shells can range in size from the smaller size of the Sennheiser IE600 IEMs to the larger size of the Empire Ears RAVEN IEMs. But bigger doesn't necessarily mean heavier—it depends on the number of drivers inside as well as the material of the earphones, which may be made from metal, plastic, acrylic, resin, or a combination.

Nozzle and Ear Tips

The part of the IEM that sits in your ear canal is called the Nozzle. Nozzles vary in length depending on the IEM. If you're using universal IEMs, the nozzle is what the ear tips attach to. Ear tips come in a variety of materials and sizes to help you achieve the optimal fit and sound. You don't have to limit yourself to the ear tips that come with your IEMs and it's worth exploring your options if you haven't found the perfect tip. The two most widely used options are silicone and foam. Silicone is the most universal ear tip type that's easy to clean and durable. Foam ear tips mold to your ears more and provide better noise isolation than silicone.

Silicone

Easy to clean

Minimal noise isolation

Durable

Single, double, and tripe-flange styles

Foam

Molds to ear canal for a secure, comfortable fit

Extreme noise isolation

Not as durable

Available in different shapes

Drivers

The Driver(s) is the heart of your IEMs. Think of an IEM driver as a miniature speaker inside the IEMs that converts electrical signals into audible sound waves that are then pushed or "driven" into your ears. Driver count depends on the IEM. Some IEMs feature one driver while others can feature as many as 11 in a pair of IEMs. If an IEM is a single-driver IEM there will be one driver per side. The Sennheiser IE 600 IEMs are single-driver IEMs. On the other hand, the Empire Ears Legend EVO IEMs use eight IEMs. Does more equal better? Not necessarily. A single-driver IEM can sound every bit as good as one with multiple drivers. There are so many factors that are going to determine the sound of your IEMs, and the number of drivers in and of itself is not going to tell you.

Alongside driver count is driver type. IEMs can feature multiple of the same driver or several different driver types. Each IEM driver type possesses unique sonic characteristics that impact the sound quality of the IEMs. A combination of more than one IEM driver type will result in a sound different from an IEM featuring only one driver type. Understanding the types of drivers will help you determine the sound you're looking for in your IEMs.

Dynamic Driver

Dynamic drivers are tiny versions of the woofers used in speakers. Dynamic drivers have a diaphragm 8mm to 11mm in diameter, connected to a coil of wire around a magnet. When an electrical signal moves through the coil, a magnetic field is created, moving the diaphragm. Dynamic drivers are the least expensive driver type and are known for their bass response. The Shure SE215 IEM is an example of a single, dynamic driver IEM. They're incredibly common in full-size headphones and featured in a lot of multi-driver IEMs.

Balanced Armature Driver

Balanced Armatures are very small, so as many as a dozen can be packed into an IEM. Typically, separate balanced armatures are used for the treble, midrange, and bass. Multiple drivers may be used for a single frequency. A crossover circuit, like those found in speakers, divides the signal into bass, midrange, and treble. Balanced Armature drivers are known for detail and accuracy, but have a less impactful bass.

Electrostatic Driver

Electrostatic drivers resemble planar magnetic drivers; the difference is the diaphragm. Electrostatic drivers have a layer of conductive material carrying a bias voltage. The two magnetic plates surrounding the diaphragm carry the audio signal. Electrostatic drivers are known for clear, spacious, detailed sound, low distortion, and treble extension.

Hybrid, Tribrid & Quadbrid IEMs

Some manufacturers make hybrid IEMs that use balanced armatures for the middle and upper frequencies and dynamic drivers for the lower frequencies. They also make IEMs that use three or more driver types to achieve various sound characteristics.

Hybrid IEMs

An example of a hybrid IEM, the Empire Ears Wraith combines seven balanced armatures and four electrostatic drivers.

Tribrid IEMs

Some IEMs combine three driver types. The Empire Ears Odin, for example, uses two dynamic, five balanced armature, and four electrostatic drivers. That's 11 drivers per side!

Quadbrid IEMs

Four driver types in one IEM? The Raven from Empire Ears combines 5 balanced armatures, 4 electrostatic tweeters, dual W9+ subwoofers, and one W10 bone conduction ultra driver in a quadbrid design. A multi-point synX crossover network is used to harmonize all of the drivers.

Buying IEMs: The Best In-Ear Monitors at Every Price Point

Moon Audio sells IEMs from several respected high-fidelity audio brands. Empire Ears exclusively makes IEMs, while other companies like Sennheiser and Meze Audio include IEMs as part of their product offerings. Like anything else, IEMs are available at a variety of price points, from pricier reference models to comparatively more budget-friendly options. But you don't have to spend a fortune on a high-quality pair of IEMs. Certainly, the more expensive the better materials and fancier technologies, but that doesn't mean there aren't phenomenal options lower down. It all comes down to sound quality. When you find a pair of IEMs that sound amazing to you, then you have your perfect match.

We offer universal and custom IEMs from 64 Audio, Astell&Kern, Empire Ears, Meze Audio, QDC, Sennheiser, and Shure. If you are interested in purchasing a custom IEM from Empire Ears or 64 Audio please reach out to us directly and we can assist you in the buying process.

Sennheiser IE600 Earphones

Sound Signature: Clear, Natural, Engaging

The Sennheiser IE 600 is a great option for audiophiles who want an IEM with a small footprint and a natural, detailed sound. The IE 600 is not as neutral or detailed as the flagship IE 900, but it's pretty good on both of those counts. The sound is relatively intimate, as you'd expect with an IEM, but the IE 600 still does a pretty good job with imaging and keeping various instruments and vocals in their respective places. While appropriate for a variety of music styles, the IE 600 works especially well with vocals, acoustic music, folk, blues, and Americana — anything that calls out for a natural yet expressive presentation.

The Sennheiser IE 600 IEM is an excellent option if you're looking for detail retrieval. There's some lovely sparkle on the top end that provides some excitement to the listening experience, and these are a delight for soundtracks as well. The IE 600 is on the small size as far as IEM chassis go, and that's great for people with smaller ears and canals.

The Bronze Dragon IEM cable will provide some additional warmth to an otherwise analytical IEM, adding meat to the sound for gaming and music at a price point more in line with a serious music lover.

Meze Audio ADVAR IEMs

Sound Signature: Neutral, Warm-leaning

The beautifully designed Advar IEM is the latest offering from Meze Audio, makers of the renowned Empyrean headphones as well as the Rai Solo and Rai Penta IEMs. The Advar is an impressive-sounding IEM, offering much more than the entry-level Solo and coming close to the performance of the Rai Penta. There's no surprise that the infamous Meze soundstage still manages to wow and amaze with each new product and iteration that they come out with, but it's the low-end presence, mid-level energy, and the high-frequency roll-off of the Advar that makes for a smooth, dynamic, and fun IEM.

When paired with the Bronze Dragon IEM Cable (MMCX) the ADVAR presents an incredibly musical presentation that's full of body.

Empire Ears Bravado MKII Custom IEMs

Sound Signature: Warm side of Neutral

The Bravado MKII is Empire's entry-level IEM–an all-purpose model that performs well in all genres. The Bravado MKII retains everything good about the original Bravado while getting a big boost in resolution and separation, thanks to the addition of two premium electrostatic drivers. With a slightly warm sound and much larger soundstage than the original, the overall effect is good, old-fashioned, unpretentious fun. The Bravado MKII features Empire Ears Weapon IX+ subwoofer, dual electrostatic drivers and EIVEC system to bring a nuanced and layered presentation that heightens the listening experience to new levels of musicality and analytical enjoyment.

Known for its engaging and fun sound signature, the Bravado MKII is tuned to emphasize bass response and overall musicality. It's designed to provide an energetic listening experience with an enhanced low-end presence, making it particularly appealing to bass enthusiasts and listeners who enjoy genres like EDM, hip-hop, and rock. As a custom IEM, the Bravado MKII is designed to fit your ears and your ears only, meaning you get the utmost comfort when listening for extended periods of time.

We recommend pairing the Empire Ears Bravado MKII IEM with the Black Dragon IEM Cable. The Black Dragon marries the sonic strengths of the Silver Dragon and Bronze Dragon IEM Cable, delivering a warm and smooth sound with a musical presentation. Copper strands enhance the body, shape, and immediacy of the music, while silver enhances detail and clarity. The detail and expansiveness of the Black Dragon make it a flexible fit where a broad range of musical genres are played.

Sennheiser IE900 Earphones

Sound Signature: Clean, Balanced, Detailed

You know you've found a keeper of a headphone or IEM when you want to keep on listening to every single piece of music you know and love. This was our experience with the IE 900 from Sennheiser: a pleasure to listen to and super comfortable to boot. A nice, full sound that sounds natural and clear -- great with blues, folk, acoustic strings, and music with lots of detail. Vocals are super clear and emotive. Treble on the IE 900 is definitely something to write home about. Lots of sparkle. Piano on several tracks sounded absolutely gorgeous. If you're deciding between the IE 600 and the IE 900, choose the IE 600 if you want a more fun sound for on-the-go listening/gaming, the IE 900 if you are all about detail and clarity and are not willing to compromise. You won't be disappointed. Of course, cost plays into it, but ultimately with Sennheiser, you get what you pay for. Be sure to add in the Bronze Dragon IEM Cable for Sennheiser for additional warmth and musicality - you'll really feel the motive properties of the IEM. 

Even though the IE600 and the IE900 might look the same, there is a substantial difference between the two sonically. You'll find a more refined sound, resolution, and slightly better imaging in the IE900. Sennheiser is known for its clarity, and the IE900 is one of our top picks for competitive gaming. The chassis is on the small side, making it super comfortable for longer gaming and listening sessions. The soundstage on the IE 900 is intimate, with layers of sound and everything clearly delineated. This is great for both immersive and competitive gaming, and we can't recommend the IE 900 IEMs enough for any gamer out there.

64 Audio U6t In-Ear Monitors

Sound Signature: Balanced, Natural

One of 64 Audio's entry-level IEMs, the U6t IEM is perfect for audiophiles craving a balanced, natural-sounding In-Ear Monitor. The U6t is slightly set apart from the other 64 Audio UIEM models by offering a softer presentation of a mix. Beautiful upper-mid imaging, realistically presenting instruments like guitars and piano as well as breathing life into saturated mid-bass mixes, especially when vocal-focused.

The U6t is equipped with 64 Audio's tia, apex, and LID technology, contributing to the overall stellar performance of these IEMs. Tia reduces unwanted resonance and distortion for a transparent and lifelike sound signature while the Apex vent releases air pressure so you can enjoy a fatigue-free listening experience. LID restores proper interaction with your source device, preserving the desired sound signature for a reliable, consistent sound. Pair the U6t with your favorite DAP, DAC/Amp, or smartphone and start listening on the go.

When paired with the Bronze Dragon IEM Cable, the U6t IEM has more musicality and warmth. The Bronze Dragon is our warm and musical-sounding IEM Cable, delivering a fuller, balanced sound with the perfect balance of warmth and detail.

Astell&Kern Pathfinder IEM Earphones

Sound Signature: Midrange Clarity, Low-End Representation, Smooth

Finally, we have the Pathfinder - which is a beautiful marriage of both Astell&Kern and Campfire Audio's design philosophies. Astell&Kern's aesthetic is based on the principles of light and shadow, which gives their products an industrial, futuristic look. Campfire Audio, meanwhile, likes to incorporate aspects of nature into their designs. The IEM is a hybrid design that uses two dynamic drivers and three balanced armature drivers. Great sound in a gorgeous package. That's the Pathfinder in a nutshell. Two of the most striking sound aspects of the Pathfinder are the depth and punch of the bass and the clarity. The bass is definitely beefy, but it doesn't overpower. The sound is rich with some midrange warmth, but also crisp, clear, and peppy. The Pathfinder strikes a nice balance in those regards. There's plenty of definition throughout the upper ranges, but the presentation is smooth. This makes the Pathfinder a versatile IEM. Rock, Folk, Bluegrass, and Jam Band music, and more shine on this IEM. The low-end weight coupled with a smoother top end will appeal to Jazz listeners - classical, too. Paired with your favorite AK DAP or other digital music player, the Pathfinder IEM is going to give you a versatile option in both sound and ergonomics for your on-the-go hi-fi listening. Be sure to pair it with the Silver Dragon IEM Cable for added clarity and detail. 

The way IEMs design their drivers - in this case - for different frequency spectrums goes a long way to enhancing the "expressiveness" of a monitor. In terms of gaming, this helps your environments come alive - giving you a presentation that you're actually there in the game experiencing the sound firsthand. The Pathfinder excels at this, providing a balanced and impactful experience in both gaming and music listening time and time again.

The thing that makes the Legend EVO stand out from other IEMs, including its predecessor Legend X, is the visceral quality of the sound, and the way you experience it both inside and outside of your body.

With a dual-conduction architecture and eight-driver tribrid system, the Legend EVO emits unprecedented levels of innovation and performance to create a new benchmark in the IEM industry.

We recommend pairing the Empire Ears Legend EVO IEMs with the Silver Dragon IEM Cable.

Powering Your IEMs

Believe it or not, there is such a thing as too little and too much power, and dancing that line can impact your IEM performance more than you might think. If you don't provide enough sufficient power to a pair of IEMs the sound quality will fall short of what's expected. On the other end, overpowering them can damage the driver and impact your hearing. There are certainly instances where IEMs can be powered efficiently by a smartphone, but it's not something we recommend (unless you have absolutely no other option). You would be doing your IEMs and your ears a disservice by using your smartphone. Here are our recommendations for portable power.

Portable Headphone Amplifiers/DACs

Just because you can power your IEMs with only your phone doesn't mean you should. In the case where using your smartphone is the only option, we recommend at least pairing it with a portable digital-to-analog converter (DAC)/headphone amplifier combo. Adding a DAC/amplifier to your phone will give you more power, clarity, and detail out of your music. And in the case where your IEMs require more power than what your smartphone provides, it'll solve that problem too.

We recommend portable DAC/Amp combo units that are USB dongles. They're the easiest option to carry around that won't take up much real estate in your pockets. Most of these USB dongle DACs will require a wired connection–the best connection–but there are a few wireless options that aren't half bad either.

Digital Audio Players (DAPs)

DAPs are the real deal for your IEMs. An all-in-one unit that's basically an iPod on steroids, DAPs have a built-in DAC, headphone amplifier, Wi-Fi, and headphone jacks. A portable DAP is a great streamlined way to enjoy high-resolution audio on the go. You'll get storage for your digital music files plus, with Wi-Fi, you can enjoy content from your favorite music streaming services.

A DAP will eliminate the need for your phone and extra cables so you can listen portably with your DAP, IEM, and IEM cable—that's it! The other great thing about DAPs is that you can use them with your headphones too.

Dragon Audio Cables

Of course, your universal or custom IEMs are going to come with a stock cable from the manufacturer–maybe multiple. And the vast majority of the time, the stock IEM cable is going to do the trick, providing you with a perfectly acceptable listening experience. However, if you are left wanting something more from your IEMs, you may want to think about a cable upgrade.

Why Upgrade? Stock IEM cables, are well, stock cables. Mass-produced and oftentimes the last link in the manufacturing chain, stock IEM cables can be made with poor geometries and materials that won't enhance the sound quality. At Moon Audio, cables are what we do, and we have spent years studying and perfecting the art and science of cable making. Using the purest UP-OCC copper and silver with 7N purity 99.99998 percent, we handcraft IEM cables to help you achieve the level of clarity, detail, warmth, or immersion that you desire from your listening experience.

Dragon IEM Cables with iems

Our Dragon IEM Cables will bring out more of what you love in your music. We offer three Dragon Audio Cable lines for IEMs–Silver Dragon, Bronze Dragon, and Black Dragon–available in 2-pin, 4-pin, or MMCX connections. Each of these lines has its unique sound signatures that will alter the tonality of your IEMs. You can add more bass, tighten up the low-end, add resolution and detail–the configurations are endless.

Generally, stock audio cables are manufactured with subpar materials, metals with impurities, poor geometries, and an overabundance of layers to make them look and feel like a fire hose. Inconsistency and lack of quality control in stock cables can lead to poor sound quality and a veiled sound vs. what the musician intended for you to hear and feel from the music. Dragon Audio Cables are handcrafted with the highest standards and made to order according to your specific needs. At Moon Audio, we create a custom cable for you using the highest quality UP-OCC silver or copper conductors that can be manufactured. UP-OCC metals are void of impurities and are optimized for signal transfer and sound quality. We have one of the largest collections of audio and headphone connection options available online and we create limitless audio cable options depending on your specific gear and needs.
Why Dragon Cables?
You’ve heard the saying that a chain is only as strong as its weakest link, right? Well, the same applies to your brand new audiophile-grade headphone or other audio components. The weakest link, in this case, is your stock audio cable or the cheap interconnects the manufacturer threw in the box just to get you up and running. Why is the audio cable always an afterthought, when it’s just as important as the rest of your system? At Moon Audio, we use the purest and best raw materials in our cables to unveil your music. We believe that materials matter and your audio cables should have the same care and craftsmanship that manufacturers put into their audio components and headphones. Audio cables are ultimately the connection to your music. The fact remains that cabling is often considered the last priority to that of the main product and a means to cut down the overall production costs. It’s as simple as that. Dragon Cables elevate every note - as if you were hearing your favorite music for the very time.
