These over-ear, closed-back headphones provide excellent sound isolation and enhanced low-frequency reproduction. Their accurate sound reproduction and high resolution make them high-quality monitor headphones suitable for recording and live monitoring. The detachable ear pads and cable make maintenance easy. This improves sound resolution, allowing you to clearly distinguish even subtle sounds. ■ The around-ear housing provides excellent sound isolation, preventing sound leakage from the headphones and preventing the microphone from picking up the headphone playback sound during recording. ■ The headband features a "mute switch mechanism" that automatically mutes the playback sound when removed from the head.
