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.

- Pro:Lightweight and comfortable for extended wear
- Pro:Detachable cables and USB-C connectivity
- Con:No included carry case or spare ear pads
- Con:Open-back design leaks sound and offers no isolation
