The Sennheiser HD 400S is a closed-back, over-ear wired headphone with a foldable frame. It needs no battery, no charging and no app, and its closed cups block room noise passively instead of with active noise cancelling. That makes it a low-maintenance second pair for desk, couch and commute, and a sensible travel set alongside an open-back at home. Against wireless rivals it trades ANC and Bluetooth for a cable that never runs out and no pairing latency; against open-back headphones it trades soundstage for isolation and portability.
