The HD 620S is a groundbreaking closed headphone that offers contemporary tuning and a soundstage that rivals its open-back counterparts. The headphone features a custom-tuned 42mm dynamic transducer, manufactured at the company's cutting-edge facility in Tullamore, Ireland. This transducer delivers a smooth and effortless sound, reminiscent of the renowned open-back 600 series while providing a modern and airy signature that balances accuracy with deep and well-defined bass.
The 150-ohm aluminum voice coil, coupled with a high damping factor, ensures rapid transients and precise instrument decay, resulting in dynamic and punchy audio across the entire frequency range. This makes the HD 620S an excellent choice for audiophiles and dedicated gamers who demand the highest level of detail in their listening experience.
The HD 620S is housed in an iconic chassis that is well-known among audiophiles, gamers, and streamers for its exceptional long-term wearing comfort. The headphone's design instills confidence while providing an immediate sweet spot for the listener. The metal components not only offer a premium feel but also serve an essential acoustic purpose. The steel plate that seals the back volume acts as an efficient isolator, effectively managing internal reflections that can negatively impact the purity of the acoustic signal.
The angled baffle design is remarkably open, promoting the free flow of air and emulating the performance of open-back transducers. This design choice allows the HD 620S to recreate the triangular imaging of a well-tuned loudspeaker setup in an expertly treated room. The result is an immersive presentation that places the listener at the center of the action, with impressive spatial cues, whether enjoying a rare live concert recording or engaging in a massive online multiplayer gaming session.
Dragon Cable Recommendation: We recommend pairing the Sennheiser HD 620S headphones with the Bronze Dragon Portable Headphone Cable. The Bronze Dragon Portable cable is designed for listening on the go with your favorite single-entry connection headphones. The Bronze Dragon helps create a warmer presentation with a bigger and fuller body, adding bottom-end strength and muscle. Our new Dragon cable is musical without becoming lush or bloated and features a very flexible cable that's perfect for on-the-go applications.
Open headphones are often preferred by audio purists due to their natural sound and wide soundstage. However, closed headphones serve a crucial role when the listener requires isolation from their surroundings. Audiophiles often have to sacrifice the open and spacious sound of open-back headphones in favor of closed-back designs to avoid distractions or to prevent disturbing others, such as roommates, spouses, or coworkers. The HD 620S represents a significant breakthrough in real-world performance, providing audiophiles with the expansive soundstage they desire without the fatiguing and confined sound typically associated with closed-back headphones. This makes the HD 620S an ideal choice for those seeking an immersive listening experience in situations where sound isolation is necessary.
The HD 620S is designed with durability in mind, featuring a metal-reinforced headband and earcup housings for long-lasting use. The headphones come with a storage pouch that provides ample space for the headphones and the detachable cable, ensuring protection from dust and tidy storage. The included 1.8 meter (6 foot) cable is equipped with a single-ended 3.5mm stereo plug and an integrated locking screw for the included 6.3mm adapter, offering a secure connection to a wide range of audio devices.
For audiophiles, an optional balanced 4.4mm cable will be available this summer, allowing users to connect to a growing number of hi-fi devices that support this increasingly popular connector. The HD 620S features a twist-and-lock single-sided cable design, similar to other Sennheiser headphones, providing users with a variety of aftermarket cable options, including different lengths and the addition of an in-line microphone for added versatility.
What are the key features of the Sennheiser HD 620S headphones?
The Sennheiser HD 620S headphones feature a closed-back design, 300-ohm impedance, improved transducers for lower harmonic distortion, lightweight aluminum voice coils, and a frequency response of 8-41,500 Hz. These headphones are designed for audiophiles, offering a natural and balanced sound signature with detailed mids and extended lows.
Are the Sennheiser HD 620S headphones comfortable for long listening sessions?
Yes, the Sennheiser HD 620S headphones are known for their comfort. They feature plush velour ear pads and a well-padded headband that distributes weight evenly across the head. This design minimizes pressure and makes them comfortable for extended listening sessions.
Do the Sennheiser HD 620S headphones require an amplifier?
While the HD 620S can be driven by most modern devices, such as smartphones and laptops, to achieve their full potential, it is recommended to use a high-quality headphone amplifier. This is especially true for audiophiles who want to experience the full dynamic range and detail these headphones offer.
What type of music sounds best on the Sennheiser HD 620S?
The Sennheiser HD 620S headphones excel in genres that benefit from a balanced and natural sound signature. This includes classical, jazz, acoustic, and rock music. Their detailed mids and extended lows provide a rich listening experience across a wide range of music styles.
How does the closed-back design of the Sennheiser HD 620S affect the listening experience?
The high-end closed-back design of the HD 620S allows for a more impactful and engaging listening experience, making the music feel more immersive and lifelike. However, they still retain a great soundstage that is indicative of open-back headphones. With a closed-back design, this means they are isolated which makes them suitable for any listening environment. They also provide more sub-bass than their open-back design counterparts, with more energy retained in the treble which can be improved substantially from the additional power from an amp or resolution from a DAC. Airflow is minimized compared to open-backs, but this helps achieve some extended sub-bass and midrange for a surprisingly exciting dynamic driver.
Are the Sennheiser HD 620S headphones suitable for gaming?
Yes, the Sennheiser HD 620S can be used for gaming, especially for those who prioritize sound quality and immersion. The closed-back design and detailed soundstage can enhance the gaming experience, although they lack a built-in microphone, so a separate mic would be necessary for communication. Like other audiophile headphones in the HD6XX lineup, vocals will shine with the detail from the HD 620S. Clamping force is extremely comfortable, but you won’t find options like Bluetooth or a carry pouch with the HD 620S. The HD 620 closes the performance gap of some of the other Sennheiser HD 600-series headphones like the popular Sennheiser HD 660S2 and 500-series like the HD 560S.
How durable are the Sennheiser HD 620S headphones?
The HD 620S is built with high-quality materials and robust construction, ensuring durability. The headband and ear cups are made from durable plastic, while the connectors and cables are designed to withstand regular use. Sennheiser is known for its long-lasting products, and the HD 620S is no exception.
