Open and closed

A legendary performance, now in closed-back.

We believe in giving high-performance audio enthusiasts the purest headphone listening experience possible — even when their surroundings are far from perfect.

The closed-back HD 620S caters to this audience by providing distraction-free listening without compromising on natural presentation. The reference-grade 42mm transducer and ultra-light 150-ohm aluminum voice coil deliver exceptional impulse response, bringing the listener to the front row of their music. 

Where many closed headphones struggle, the HD 620 excels, preserving the detailed, smooth sound the 600 series is known for while providing expansive, panoramic imaging. To mimic the presentation of loudspeakers, the HD 620S features angled transducers nestled in a remarkably open baffle. Even in complex music, bass, mids, and vocals are delightfully layered with distinct instrumentation and nuance.  

The steel-reinforced headband sliders and earcup covers ensure long-term durability while reducing unwanted resonances, all in a lightweight chassis designed for all-day use. Supple artificial leather earpads offer both a comfortable touch and superb acoustic isolation. The HD 620S includes a detachable 1.8 m twist-lock cable with a 3.5 mm plug and a 6.3 mm adapter. It's also upgradeable to an optional balanced cable with a 4.4 mm plug, seamlessly integrating into high-performance audiophile setups of all kinds.

Kitchen talk off. Sofa concert on.

Enjoy undisturbed privacy while listening to exceptional open, natural sound.

Wish your surroundings were more suitable for enjoying long listening sessions? Well, now you no longer have to trade an impressive soundstage for privacy. The HD 620S lets you experience detailed, spacious sound like never before in closed-back headphones. The stainless-steel reinforced ear cup covers not only add timeless appeal to this masterpiece; they also provide a private listening session regardless of your surroundings.

So if you’re more into sofa concerts than kitchen talks, the new HD 620S offers you a distraction-free listening experience with true-to-life vocals, letting you relive spectacular live moments without compromising on natural, airy sound. 

Who says that closed-back headphones can’t sound so real?

Distraction off. Open sound on.

Open sound in a closed-back design.

You might think that’s impossible. Think again. The HD 620S combines the DNA of the HD 600 and 500 series, bringing the best of both headphone families to a closed chassis.

Sennheiser’s HD 600 series has long been the standard for natural tone, thanks to our dedication to continuously improving the open-back concept. The 500 series introduced later offers a soundstage that immerses listeners in their music.

The distinctive DNA combination of these two series lets the HD 620 excel where many closed headphones struggle, preserving the detailed, smooth sound the 600 series is known for. Our reference-grade 42 mm angled transducers with 38 mm diaphragm and ultra-light 150-ohm aluminum voice coil deliver exceptional impulse response, expanding the stereo image to an almost panoramic soundstage.

Stressful life off. Peace of mind on.

Timeless functionality and comfort.

The HD 620S not only offers timeless design, but also timeless function and comfort. So your mind can focus on other things than high-maintenance headphones.

The HD 620S chassis is lightweight yet familiar, bolstered by premium touches that will deliver its unique acoustic signature for years to come. The robust, steel-reinforced headband sliders and ear cup covers add timeless appeal and long-term durability to a silhouette sculpted for all-day wearing comfort. Spacious ear cup covers and the supple ear pads made from artificial leather not only offer superb acoustic isolation, but also add a comfortable touch thanks to internal venting. 

The HD 620S is ready for hours of fatigue-free, intimate listening — wherever you may take them.

Key clicks off. Full immersion on. 

Your passion knows no boundaries. Why should your headphones?

Who doesn’t sometimes want to just switch off and become immersed in their own world undisturbed, away from roommates or family?

With the HD 620S, you can stay in the same room without compromising on privacy. Even better: without compromising on natural, expansive sound. Imagine hearing every nuance from every direction without any disturbance. No matter if you love gaming, amateur music production, or simply listening to exceptionally good audio, the HD 620S takes your hobby to the next level and boosts your emotional experience.
