SonicPro ハイレゾアクティブノイズキャンセリングヘッドホン（リファービッシュ品）

The ATH-MSR7NC headphones combine the Hi-Res Audio technology and design features from the original ATH-MSR7 with newly developed active-noise cancelling technology to bring you the ultimate listening experience.

These headphones are outfitted with exclusive 45 mm True Motion Drivers to deliver distortion-free audio reproduction with extended frequency response. A miniature microphone is incorporated into the top of each earcup to pick up ambient noise that can then be blocked by an appropriate sound-cancelling signal when the active noise-cancelling function is activated. Having the microphone on the top, instead of on the side, of the housing ensures consistent noise cancellation unaffected by the user's head movement or by wind noise. Each earcup also has an acoustic vent, ideally positioned on the side of the housing, 90 degrees from mic, to enhance tuning without negatively affecting sound quality. The result is consistent Hi-Res Audio reproduction whether in active or passive noise-cancelling modes.

Features:

• Exclusive 45 mm True Motion Drivers, featuring a highly responsive diaphragm and lightweight voice coil, deliver Hi-Res Audio with controlled transients
• Noise-cancelling and venting technologies work together to maintain the Hi-Res Audio reproduction in both active and passive noise-cancelling modes
