Sennheiser HD 600

The HD 600 is an open-back wired reference headphone with a 300-ohm impedance and 260 g weight, assembled in Ireland according to Sennheiser. RTINGS measured a flat, well-matched response with excellent consistency, though bass rolls off, as is common for open designs. It needs a capable amplifier to reach its potential and offers no microphone, controls or isolation. It suits critical listening and studio reference work at a desk, not noisy rooms or casual gaming.

  Found the flat response close to target apart from rolled-off bass, with excellent consistency and well-matched drivers, while noting no microphone, almost no isolation and plenty of audio leakage.

  A new owner finds the addictive mids and warm tone tempt them to crank the volume to concert levels, forcing self-discipline to protect their hearing.
