Audeze Mobius Headphone Review

A Leg Up on the Gaming Competition

Music is my passion. Playing, listening, recording, and performing; it drives me.  But there's a close second: gaming.

Last month I had the opportunity to review the Mobius Gaming Headphone from Audeze. Audeze (pronounced "aa-de-zee" like odyssey) is a well renowned audiophile-grade headphone manufacturer that makes some very nice products. The Mobius is a new venture for them into the world of gaming. After a few weeks using it, you would think gaming headsets were old hat for a company like Audeze. Is this a perfect marriage of audiophilia and gaming? Let's find out.

The Audeze Mobius Gaming Headphone with the Bronze Dragon Portable Headphone Cable: A Perfect Match.

What's In the Box

Audeze did a neat homage to video game box art in their own design: showing features on the right-hand side of the box with "PC Gaming Optimized" and "MAC Compatible," resembling the ESRB rating system labels on all game packaging. They're aware of their target audience here.

Opening the box, you have two smaller cardboard boxes containing the manuals and a cloth carrying bag for the headset. Its apparent that the carrying bag isn't going to offer much protection for this expensive gaming headphones, but Audeze does offer a very nice hard-shell case separately for the Mobius model. The cloth bag is a nice touch anyway. Under the divider containing a schematic of the headphone design is the headphone itself, along with the cables and microphone in the middle. The entire packaging is very nice and protects the products well.

Materials, Quality, and Comfort

The body of the headphones is mainly made of hard plastic with a silicone/rubberized material giving the Audeze Mobius a stealth or matte finish. Despite the body being plastic, in no way does this headphone feel cheap. The plastics used are dense, durable and weighty. In one of Audeze's promotional images, they show the headphones being twisted way past what I would consider to be the breaking point for most headphones on the market. It's quite impressive, though I admit I didn't have the testicular fortitude to try. A positive note is that due to the flexibility of the headband, the fit was never uncomfortably tight around the head. I have a larger head than most, so I consider myself quite sensitive to headband pressure; fortunately, I did not experience any with the Mobius. The earcups never felt "weighty" around my ears, and although the headband is only cushioned partially on the underside, it's cushioned in all the right spots with more than enough coverage for my noggin'.

The earcups are faux leather, and the memory foam is great at making a good seal around the ear (the same material used for the headband padding also). Audeze is known for their ergonomic cup designs, as they should be, being a premier audiophile headphone manufacturer. Your ears do not lay flat on your head, so why would the earpads also be uniform in height? Audeze designs their ear pads to be thicker in the back, where your ears are furthest from your head. This allows the drivers to be angled appropriately also to aim down the canals of your ears, rather than pointing at your head or an angled part of the ear. The height of the pads also prevents the ears from coming into contact with the cups of the headphones themselves, allowing for a very comfortable listening experience.

The headphones are heavy. Being a closed-back design and considering the amount of technology these things pack in the ear cups, it's understandable. There were moments where I had to ventilate during long listening or gaming sessions, but I've had much worse experiences with traditional "gaming" headphones (I'll leave out specific brand names). I will mention that the headphones allow your ears to sit naturally and not be pushed to your head, due to the excellent design of the ear pads. This made longer listening/gaming sessions more frequent and enjoyable. I wouldn't trade the comfort, fidelity, and weight of the Mobius over any other gaming headsets on the market. It hits all the right buttons.

Sound Quality

From a gaming headphone perspective, I was very impressed with the overall fidelity of the Mobius. The stock cable that came with the headphones is nothing to write home about. However, when connecting the headphone to a custom Bronze Dragon cable there are some noticeable and significant sonic improvements.

Let me reiterate: the stock cable that comes with the Mobius headphones does not sound bad. The Mobius sounds great out of the box, they just really perform when connected to a Bronze Dragon cable. The Bronze Dragon is the newest member of the Dragon Cables family, and it was primarily designed to combat the thin, cold sound of older IEMs. It utilizes 99.99998% UP-OCC copper strands and strengthens and expands bottom-end instruments like the bass and cello. The resulting sound from the Bronze Dragon is more musical without becoming lush or bloated. The warmth and fullness of the cable creates the muscle needed to round out a flat or bright sound signature (see here for more on sound signatures*). The copper in the Bronze Dragon certainly rounded out the lower frequencies and tightened up the bass while also providing a little dB boost in the overall headroom.

I'll be honest, at first, I picked the Bronze Dragon for aesthetic purposes; matching the "Team Copper" design option on the Mobius, but after listening to the more natural and analytical signature of the headphones themselves, adding copper to the line was the right move. Rounding off the high frequencies and allowing the mids and lows to breathe in the mix really helped the Mobius flex its muscles. Bass was punchy and tight, and surprisingly present without being overwhelming. Like Goldilocks, it wasn't too much or too little: it was just right.

There is a firmware update from Audeze that supposedly improves the microphone gain, but I was not able to install and test it at the time of this review (see update below).

On the left ear cup which the microphone attaches to there is a mute switch on the upper part of the outer side of the cup itself. The small notch makes it easy enough to find when wearing the headset, though I found myself not using it that much. If I needed to mute the microphone for extended amounts of time, I found myself just disconnecting the mic altogether. Either way, it's a nice feature to have.

[UPDATE OCTOBER 2019]: The latest version of the Mobius Firmware (V1.7) address a lot of the issues with the boom microphone, including improving the gain and overall post-processed filtering. Check out the latest control software from Audeze and the latest firmware update for the Mobius here or at the link below.

Audiophile or Gaming Headphone: Can it be both?

From an audiophile perspective, the sound of the headphone is always going to be of principal importance. As a gamer, you're not going to buy a pair of headphones based on the quality of the microphone either. So, the predicament then becomes how to have a great set of headphones while also getting a great sounding microphone? In reading a lot of audiophile blogs and forums online a common trend emerges: if you have a favorite pair of headphones then use them. Fortunately, in today's market, there are a lot of great wired or wireless microphone attachments that can be connected to your headphones. Popular streamers also use a desktop mounted condenser or run their audio through a separate interface.

There are a lot of workarounds for getting great microphone audio while simultaneously using your favorite pair of headphones, but there is one thing those options do not have: convenience. If you have a standard desktop set up year-round and only want to use one pair of headphones, then great. Most people, including myself, have various set-ups; I might want to use the Audeze Mobius on my gaming laptop when traveling, or perhaps I want to hook it up to my Xbox. The convenience of not having to set up or travel with an extra microphone, cables, etc. cannot go unnoticed.

But the Mobius microphone isn't bad. It could just be better. That statement could be applied to every gaming headset on the market right now. If you spend the time to configure the boom mic with your personal set up, then it will get the job done. It's probably not going to be much of an issue for the average consumer, but the audiophile and pro-audio crowd might be more sensitive to it. The added benefit of the Mobius is that you don't have to run any wires if you don't want to.

Look Ma, No Cords!

Oh, did I forget to mention that the Mobius can run double duty as either a wired or wireless headset? There is a lot of tech packed into the Audeze Mobius headset, and the functionality is impressive, to say the least. The term "Bluetooth"" is often treated as a 4-letter word in the audiophile community. The "B" word has the connotation of inferiority since there is a quality loss in the form of compression when transmitting audio wirelessly. From an audio quality perspective, a wired headphone will always sound infinitely better than a wireless one.

However, Audeze has implemented SBC, AAC and LDAC codecs for the Mobius. SBC (low-complexity subband) and AAC (advanced audio codec Apple and Youtube) are common in a lot of wireless devices. Audeze claims that the Mobius features Bluetooth functionality with almost three times the data bandwidth as other Bluetooth headphones. This statement comes from the fact that it implements the newer LDAC codec from Sony. LDAC can supposedly stream audio at up to 990 Kbps at 24 bits/96 kHz. Sony claims that LDAC is even closer to lossless audio due to its higher bitrate, audio sampling, and definition.

Now if the Mobius actually delivers on Sony's claim, that would be a different story. Perceptively, I did think the Mobius sounded clearer and more dynamic than some other major Bluetooth headphone competitors on the market. SoundGuys.com did an interesting test on LDAC codecs and found the 990Kbps version reaches all the way to 48 kHz, however, its resolution and noise floor is nowhere near 24-bits and are worse than 16-bits above 15 kHz. Technically by these numbers, LDAC codecs do not transmit true high-resolution audio. Now whether or not you'll be able to tell the difference is another story entirely. It does sound distinguishably better than any other Bluetooth headphone competitor out there.

The Audeze Mobius also has the ability to connect via USB-C and Auxiliary. Unfortunately, due to the amount of technology packed into these headphones, USB-C is the only method where the headphones can transmit audio passively. This means you'll have to use the battery on the device when using the Aux or Bluetooth options. I was getting about 10 hours of battery life on Bluetooth. I think that's perfectly reasonable for a wireless gamingheadphone these days. Again, being packed with so much tech, planar magnetic drivers, a detachable boom microphone, the battery life will get you through a couple of long gaming sessions without having to charge. I wasn't complaining.

The sound effects of the open-world really stand out with the Mobius. @theguyinthespacesuit

Playing Assassin's Creed in stereo gives you an immediate 180-degree plane of auditory cues. On the ground, if you have someone approaching by horse on your left (outside your field of view, or FOV), then you hear that effect sound from the left ear. If you have the same person coming from the left but more behind you, then the sound will still come from your left ear, but the 3D algorithm processes in real time how best to simulate that audio source directionally. For example, if a sound comes from 45 degrees to the left, the left ear will get the sound first and then the ITD (Inter-aural Time Difference) delay is calculated using the head size and fed to the right ear. In addition the levels are also changed. Then for certain frequencies the head shadowing is applied. HRTF is also applied to transform the audio before room reflections are calculated. Audeze also uses ILD (Inter-aural Level Difference) in the equation. It's the best way stereo spread can simulate three-dimensional audio. In Mobius' 3D emulated audio, it widens the soundscape and simulates the sound coming from behind you. In a game where stealth and defense are important, this can play to your advantage. Our brain uses a few different techniques to figure out the direction of audio:

1. ITD, ILD, head-shadows, etc.
2. If you are in an anechoic chamber and if someone blind-folds you and you keep your head still and your brain will have a very hard time figuring out front-to-back localization (i.e., it's very hard to tell if the sound is coming from the front or back). The moment you get reflections your brain can immediately perceive the direction. Visual cues can also help the brain figure out the audio direction.
3. Small micro-movements of your head - even if you don't notice it - is always happening; your head is always moving slightly. The brain uses these movements (both micro and macro movements) to figure out audio direction. You will also notice this phenomenon in animals: dogs will raise their head and turn their ears to figure out noise direction. Audeze did extensive test on head-tracking / no head-tracking and the 3D perception is always much better with head-tracking; it eliminates the cone-of-confusion issue.

One thing to keep in mind for the audiophiles is that the 3D Audio function only works in 16 bit / 48k, so you'll have more compression to deal with than high-resolution mode.

There is a function to turn on "dynamic" 3D audio which re-centers the audio after turning your head. I didn't find this feature to be terribly useful, due to the fact that it took the headphones about a 1-2 second delay in responding to your new POV. I couldn't really understand a scenario where you would turn your head and leave it there while playing a game. Secondly, when adjusting my head, I found that the audio did not re-center accurately some of the time. Perhaps this might be useful if you wanted to have 3D audio while walking around and listening to music, but from a gaming perspective, the dynamic audio wasn't all that compelling.

The only applications where I see the 3D audio as useful in gaming is a multi-monitor setup or VR. The 3D emulation shines when you have to really be moving your head around. I did find a very cool application in using it with the Nintendo 3DS handheld console. On the classic game, The Legend of Zelda: Ocarina of Time, the 3DS console implements a redesigned control scheme from the original game which utilizes the on-board cameras and gyroscopes to be able to pivot and turn your character in first-person mode. It was wild using this in tandem with the Mobius' 3D audio emulation because the audio syncing with the video in movement really adds to the immersion factor and surround realism.

Let's say you are watching a movie on an iPad on a train and you have the headphones centered to the screen. When the train changes direction, the center therefore changes as well. The dynamic mode automatically centers the headphones for these use cases. This is also a reason why it is enabled by default for Bluetooth connections and not for wired connections. The reason Audeze changes the centering gradually is because a more rapid change can be quite disorienting and confusing. Outside of the United States, mobile gaming is much bigger and people use it with phones all the time. But unfortunately it's not a great feature for desktop gaming applications. The 3D audio on the Mobius was certainly enjoyable to use. It adds a different auditory element to the gaming experience for sure, but if you're looking to buy these headphones specifically for this function and expect it to raise your gaming aptitude to a new high, then you'll be disappointed.

The Verdict

The Audeze Mobius is my favorite gaming headphone on the market right now. Buy it for the sole fact that it is an amazing headphone, first and foremost. The quality of the sound out of your headphones should be your principal interest whenever considering adding a new pair to your collection. From an audiophile perspective, the fidelity of the wired audio lives up to Audeze's legacy of making some great sounding audiophile-grade headphones. Smooth highs, clarity in the mids and tight bass make these a true pleasure to use in any scenario, gaming or not. Add in a Bronze Dragon cable and you have the cherry on top. The soundstage is surprisingly wide for a pair of closed-back headphones but combined with planar magnetic drivers, you have an audiophile-grade gaming headset capable of accurate sound reproduction.

The microphone is by far the weakest part of the package, but again, it's fine. I come from a pro audio background too, so I'm probably going to be a little harsher than others. The versatility is a strong selling point of the headphone. Being able to use it connected to USB, Aux or Bluetooth offer more options than most headphones on the market today. The wider soundstage on these headphones as mentioned previously really opens up the game world through details and dynamics. I mostly used them in high-quality stereo mode and was completely floored by the quality of the game effects that suddenly stood out to me and the definition it brought to the overall mix of the game, effects, music, and dialogue.

Audeze has done a marvelous job providing a product that targets both audiophiles and gamers, but therein lies the problem. The Audeze Mobius retails for $399. For most audiophiles that price probably comes across as very reasonable compared to what most audiophile equipment goes for. However, for gamers, the most popular high-end gaming headsets only run about $100-150. The jump to $400 might be too much for some, but if you are interested in upgrading your audio experience in the same way you upgrade your gaming system specs, then the Audeze Mobius is absolutely worth it. The number of features and overall versatility of this headset makes it top dog in my book. I'll be using the Mobius for all my gaming sessions from now on.
