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 620S 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. That's not only uniquely rare for a closed-back design; it will switch your understanding of closed-back headphone sound.

Stressful Life OFF. Peace of Mind ON.
No matter whether all day, all week or all year. 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. Are you ready to switch?

Key Clicks OFF. Full Immersion ON.

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 passion to the next level and boosts your emotional experience. So, if you're looking for spatial awareness and extraordinary detail retrieval, there's no need to wait. It's your time to switch to the new HD 620S.
