Sennheiser HD 400S Over-Ear Headphones - Black | 508598

Not everything needs a battery. The Sennheiser HD 400S is a wired over-ear pair with a closed-back design, delivering balanced, immersive sound with natural isolation from the world around you. A low 18-ohm impedance means it drives easily from a phone, tablet or laptop without an amplifier, and the frequency response spans 18Hz to 20,000Hz. The detachable 1.4m cable includes a one-button remote and microphone, so calls and playback can be managed without reaching for your device.

In daily use, the appeal is simplicity. There is nothing to charge and nothing to pair, so the headphones are ready whenever you are, at a desk, on a commute or at home in the evening. The lightweight build keeps them comfortable through long listening sessions, and the foldable design makes them easy to store or carry. Closed-back earcups provide passive noise isolation that helps you concentrate, and because the cable detaches, a worn lead can be swapped rather than retiring the headphones.
