Ratings

After analyzing verified user reviews across multiple platforms and languages, we've compiled the aggregated feedback for the Sennheiser HD 620S Audiophile Closed-Back Headphones. We considered only authentic, high-quality reviews, filtering out spam, bot, and exaggerated feedback. While users consistently praised the premium audio quality and comfort, a few noted that the impedance requires an external amp for optimal performance. Below, you’ll find detailed ratings based on key factors that matter most to buyers, reflecting both strengths and pain points.

Audio Performance
94%
Many users rave about the impressive audio fidelity and clarity of this headset. The spatial soundstage and deep bass reproduction make listening an immersive experience, with vocals coming through crisp and lifelike. Audiophiles especially enjoy the balanced sound across a wide frequency range, from low-end warmth to high-end brilliance.
However, some users feel that the sound signature might be a bit too flat for those who prefer extra emphasis on bass. Additionally, while the clarity is praised, some report that it can take some time to adapt to the relatively neutral sound profile if you're used to more colored audio.
Comfort for Long Listening Sessions
88%
Comfort is a major plus for many buyers. The soft, plush ear cups and lightweight design allow for long listening sessions without causing discomfort. Whether for casual listening or extended audiophile sessions, users often mention how these headphones don't cause fatigue, even after hours of use.
Despite the comfort, a few users find the headphones a bit heavy, especially if worn for prolonged periods. The over-ear design, while great for sound isolation, might also feel a bit snug on users with larger heads or those who wear glasses.
Build Quality
92%
The build quality of this headset is frequently praised for its robust design and premium materials. Many users report that the headphones feel durable and solid in hand, while the sleek design gives them a high-end look and feel. The materials used, from the metal frame to the high-quality plastics, contribute to a feeling of long-term reliability.
Some users have noted that the overall weight of the headphones can make them feel a bit cumbersome, especially during transport. Although durable, the plastic elements may show some wear over time, and there are occasional reports of the headband being prone to small scratches.
Value for Money
87%
Many buyers consider these headphones a great investment due to the premium sound and comfort. The overall performance relative to the price is often highlighted as a good balance, especially for audiophiles seeking high-fidelity sound. The durable build and long-lasting comfort add to the perception of solid value.
However, some feel that the price tag is a bit steep compared to other similar offerings on the market. While the audio quality is exceptional, some users think that a more affordable option could offer a similar listening experience, particularly for those on a budget.
Soundstage & Imaging
91%
Users are consistently impressed by the wide, natural soundstage and precise imaging that these headphones deliver. Many mention how instruments are placed distinctly within the mix, creating an expansive, three-dimensional audio experience. Whether listening to live recordings or complex orchestral pieces, the imaging is praised for its accuracy.
On the flip side, some listeners feel that the imaging could be more dynamic. For those accustomed to headphones with a more forward soundstage, these may feel slightly reserved, which might not suit users seeking more aggressive spatial effects.
Compatibility with Devices
80%
20%
These headphones work well with most devices, from smartphones to high-end audio equipment. The 3.5mm jack makes them compatible with a wide range of sources, ensuring ease of use with both portable and stationary setups. Many users mention they work effortlessly with most common audio gear.
That said, some users report that the 150-ohm impedance can affect performance when paired with lower-powered devices like smartphones or laptops. A headphone amp is often recommended for optimal sound, which may be an additional cost or hassle for some users.
Portability & Size
76%
24%
These headphones are well-suited for home use, with a design that’s comfortable and secure. The folding mechanism and detachable cable provide some convenience for storage, although they are not as portable as some smaller models. They are ideal for stationary setups and audiophile systems.
However, their larger size and weight make them less than ideal for portable use. Travelers or commuters who prefer compact headphones may find these cumbersome to carry around, and they take up more space in a bag compared to on-ear or over-ear models with a more compact design.
Ease of Use & Setup
82%
18%
The headphones are straightforward to set up, requiring no complex installation or software. The 1.8m cable length gives users flexibility in how they connect to audio sources, and the simple 3.5mm connector works with a wide variety of devices. Many users appreciate the plug-and-play nature.
Some users wish the cable was a bit longer or provided with different connectivity options, especially for users with stationary setups or audio equipment placed at a distance. Additionally, the lack of wireless options might be a dealbreaker for those seeking a more convenient, untethered listening experience.
Noise Isolation
89%
The closed-back design does a great job of blocking out ambient noise, allowing users to fully immerse themselves in their music without distractions. Many users mention how effective these headphones are in noisy environments, such as busy offices or public spaces.
While noise isolation is generally good, some users still report leakage in certain high-volume situations. It’s not as effective at blocking external noise as active noise-cancelling headphones, which may be a downside for those needing total isolation in very loud settings.
Durability
90%
These headphones are built to last, with many users reporting that they hold up well over time. The solid construction and quality materials provide confidence that they will endure heavy use. The headband and ear cups show little wear after extended periods, maintaining their sturdy feel.
Despite the overall durability, a few users have mentioned that the ear pads and headband padding can start to show signs of wear after frequent use. The plastic components, while strong, might develop minor cosmetic scratches after handling, which can affect the aesthetic appearance.
