Sennheiser HD 400U
A USB-C digital audio feed delivers Sennheiser's balanced, detailed sound in a lightweight 218-gram foldable closed-back design that passively cuts ambient noise. Replaceable ear pads and a durable build ensure lasting comfort, while the removable cable system supports the included inline remote cable or an optional analog connection. It's best for remote workers and students needing a reliable, portable headset for calls and video chats, not critical music listening.
