The Sennheiser HD 400U wired headphones connect via USB-C and deliver natural sound through a lossless digital connection. The closed-back over-ear design blocks out external noise, while the dynamic driver produces clear, expressive sound with deep bass. The built-in omnidirectional microphone and in-line controls let you manage calls and music without the need for a battery.
The plug-and-play connection works with laptops, tablets, and smartphones. The detachable cable makes the headphones easy to use and carry.
