Key Features
With two microphones in each earcup and Dual Noise Sensor technology to capture ambient sound, you can block outside noise everywhere you go, so the only thing you hear is your music.
The Integrated Processor V1 helps to eliminate external sound, with a low processing delay to make the Noise Cancelling more effective than ever.
A newly developed Wind Noise Reduction Structure around the mic reduces background noise for you, and keeps focus on your favourite music.
In Ambient Sound mode, the WH-CH720N headphones capture more of the ambient sound around you thanks to the feedforward and feedback mics, so you can enjoy a natural listening experience while staying connected to your environment. Plus, the Sony | Headphones Connect app allows you to adjust the ambient sound in 20 levels, or use the Focus on Voice setting to chat without removing your headphones.
