The HD9 headphones are built for situations where isolation matters -- tracking vocals in a live room, monitoring in a noisy environment, or mixing when you can't use speakers. The closed-back design keeps outside sound from leaking in and prevents your audio from bleeding into nearby microphones. The 45mm neodymium drivers cover a wide 10Hz to 26kHz range with the detail you need for critical listening.

The circumaural design wraps fully around your ears for comfort during long sessions, and the detachable cable makes replacement easy when wear inevitably takes its toll. These are straightforward professional monitoring headphones -- accurately voiced, well-isolated, and built to last. A solid choice for recording sessions, live sound monitoring, and focused mixing work.
