What reviewers said
Sennheiser HD 400
These over-ear Sennheiser headphones are built around a neutral, open-back design aimed at studio work, delivering a wide soundstage and detailed, transparent audio for critical listening. They are lightweight and comfortable for long sessions, with a high-impedance driver setup that helps maintain low distortion, though they lack isolation and come without a carry case. Wired connectivity via USB-C and detachable cables adds versatility, but the open-back nature means sound leaks both ways.
