Get the most from your
WH-CH720N with the Sony | Headphones Connect app

Download the Sony | Headphones Connect app to adjust settings, including Multipoint Connection, Ambient Sound mode, and more. Lots of the settings we mention on this page can be tailored to your preferences using the app.

To have access to all the functions available to you within the app, you will be required to sign in or create an account.

Sound features
Adaptive Sound Control

Optimise the switching for you

This feature learns how you use the headphones while using Adaptive Sound Control and switches settings at an optimal time.

Just enable this setting and follow the on-screen prompt to sign into your Headphones Connect app account.

Action-based settings

The Headphones Connect app detects what’s happening around you and what you’re doing. Then it adjusts settings like Noise Cancelling and Ambient Sound levels automatically. So, if you’re running, ambient sound levels might go up, then go down when you’re sitting in a cafe.

How to get started with Action-based settings

In your Headphones Connect app, within the Adaptive Sound Control setting, enable “Detection of Actions” to begin with the default detection settings.

You can stick with default settings or change them to your liking, for example, putting Ambient Sound levels up when you're walking to hear the world around you.



Noise Cancelling and Focus on Voice

Shut the world off and hear only what you want to hear – from nothing at all to voices only.

How to adjust Noise Cancelling

Don't miss out on your favourite sounds, no matter where you are. Adaptive Sound Control can cancel external noise, while also letting in voices so you don’t miss important announcements, for example, on your daily commute.

Ambient sound pre-sets

Increasing ambient sound using the 20 pre-sets in the app lets you listen to ambient sound more naturally, even with headphones on. Within the Ambient Sound Control setting, simply move the slider.

Focus on Voice

You can also use "Focus on Voice" to enhance voices and suppress noise for chatting without removing your headphones. To do this, simply highlight the “Focus on Voice” check box.

Wind noise reduction 

Your headphones also feature a wind noise reduction structure that automatically reduces wind noise from your voice during phone calls and when playing music with Noise Cancelling/Ambient Sound Mode.

Changing settings by location

Set up your headphones to change settings to your liking at the locations you visit frequently.

Fine-tune your equaliser settings and adjust your streaming and upscaling settings for a better listening experience that suits your taste.
