40mm speaker driver delivers sound without distortion
The 40 mm speaker driver is made of a composite mylar material for a highly sensitive yet powerful element that delivers sound without audible distortion.
Closed acoustic system blocks out ambient noise
Sounds around you are perfectly blocked out while the sound from the headhone is kept in a sealed chamber for perfect quality. This makes the headphone great for monitoring during live music or recording sessions.
The whole ear is covered to optimize sound quality
Full-size earshells of these Philips headphones not only cover your whole ear for better sound quality, but also provide space for a larger, higher performance driver.
