Dual Noise Sensor technology and an Integrated Processor V1 take Noise Cancelling to the next level. Now you can shut the world around you out and immerse yourself in the music. You can also adjust the ambient sound across 20 different levels with the Sony | Sound Connect app.

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.
A newly developed Wind Noise Reduction Structure around the mic reduces background noise for you, and keeps focus on your favourite music.
The Integrated Processor V1 helps to eliminate external sound, with a low processing delay to make the Noise Cancelling more effective than ever.
Carefully designed with you in mind, a lightweight, ergonomic construction makes the most of the 35 hours battery life and will stay comfortable for long periods of listening.

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 | Sound 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.
The WH-CH720N headphones include soft, oval-shaped earpads so you'll never need to take a break from your favourite music. Comfortable synthetic leather and urethane materials combine with optimum ear pad structure and dimensions for exceptional wearability.
With Precise Voice Pickup Technology, Wind Noise Reduction Structure, and beamforming mics to pick up your voice, you will enjoy clearer calls and better conversations.
With up to 35 hours of battery life, you'll have enough power to keep listening all day and into the night. And if you need to top up in a hurry, a 3-minute quick charge will give you up to 60 minutes of extra play time.
Battery life is up to 50 hours with Noise Cancelling off.
Beamforming microphones with Precise Voice Pickup technology are smartly positioned to pick up your voice more clearly and accurately, in a range of environments.
