Sennheiser HD620S

Vocals are reproduced faithfully, intended to allow you to hone in on detail in that specific band. HD620S's driver delivers exceptional impulse response, ensuring the music attacks and decays with accuracy.

The core of the HD620S is a custom-made 42mm driver, crafted in Sennheiser's cutting-edge facility in Tullamore, Ireland. 

This driver builds on the smooth, effortless sound of the open-back 600 series, adding a touch of modern airiness for a balanced soundscape with clear highs and deep, detailed bass.

Sennheiser's thin and light 150ohm aluminum voice coil delivers crisp transients and instrument decays, resulting in impactful dynamics throughout HD620S's entire frequency range – a win for audiophiles and gamers who crave rich sonic detail.

The HD620S boasts a legendary design known for its exceptional comfort, a favourite among audiophiles, gamers, and streamers alike. Its metal accents are not just for aesthetics. The steel backplate effectively isolates sound, minimising internal reflections that can muddle your audio.

Sennheiser's cleverly angled baffle promotes airflow, mimicking the behaviour of open-back headphones and recreating the expansive soundstage of a high-end speaker setup in a perfectly tuned room.

HD620S's immersive experience places you right in the heart of the action, whether you're enjoying a rare live recording or an intense online multiplayer battle.

The trade-off between open and closed-back headphones is a familiar one for audiophiles. Open-back designs offer a more natural sound and wider soundstage, but leak sound and provide little isolation. Closed-back headphones excel at blocking out external noise but often come at the cost of a more "boxy" sound.

Use these with any portable source available – anything as small as iBasso Audio's DC03 Pro that swings voltage will drive the HD620S. Step up to the desk with iFi Audio's hip-dac 3 and ZEN DAC V3. And Sennheiser's 150ohms will even suit high output impedance and suspect voltage sources in the studio, providing an accurate response.

HD620S represents a breakthrough, achieving the spacious soundstage desired by audiophiles without the drawbacks of typical closed-back headphones. Check out the rest of Sennheiser's releases here, or our other headphones here.
