Pure Sennheiser Sound - Digital Over USB-C!
The HD 400U delivers pure sound via a modern USB-C connection. No pairing. No batteries. Just pure, uncompressed sound—instantly. At the heart of the HD 400U is the characteristic Sennheiser sound: carefully tuned to be balanced and natural, it brings out emotional details that often disappear with ordinary headphones.
Clear, expressive mids, sparkling highs and deep yet controlled bass combine to create an authentic, impressive listening experience that remains true to the music. The HD 400U is an open-back headphone that reproduces sound openly and transparently. The headphones come with a 1.4 m cable that's easy to store.
USB-C Connection for Simple Plug-and-Play
The digital USB-C connection delivers uncompressed sound straight from your device to your ears. Without annoying pairing or batteries, the HD 400U offers a reliable plug-and-play experience with compatible smartphones, tablets, laptops and computers. Just plug in and press play.
Compact Design, Perfect for On the Go
The HD 400U is lightweight and secure, providing hours of comfortable listening. The closed over-ear design passively isolates noise while still delivering great sound. With soft, replaceable ear pads and a foldable construction, it's ideal for work, travel and daily use.
Flexible and Practical
Thanks to the detachable cable system, you can easily connect it to different devices. Use the supplied USB-C cable with integrated remote and microphone for calls and playback, or switch to an analog cable if needed (optional).
