A Listening Experience Just for You
The Sony WH-CH520 Wireless Headphones are designed to provide a high-quality listening experience with sound that can be personalised to your preferences.
Sony's Digital Sound Enhancement Engine (DSEE) restores high-frequency elements that can be lost when an original music source is compressed. This helps produce high-quality sound that's closer to the original recording.
You can also tailor the sound to your own taste using the Sony | Headphones Connect app. Choose from a variety of presets to match the sound to the genre of music you're listening to, or create and save your own EQ settings.
The WH-CH520 is also 360 Reality Audio Certified. By analysing your individual ear shape through the Sony | Headphones Connect app, you can optimise the listening experience for more immersive music.

Designed for Everyday Life
With up to 50 hours of battery life, the WH-CH520 lets you listen without needing to recharge frequently.
When the battery is running low, a 3-minute quick charge provides up to 1.5 hours of playback, helping you get back to listening quickly.
For comfort, the headphones feature an adjustable headband, soft earpads and a lightweight design, allowing you to find a suitable fit for longer listening sessions.

Easy Connection and Operation
The WH-CH520 features Multipoint Connection, allowing the headphones to be paired with two Bluetooth devices at the same time.
This means you can connect devices such as a laptop and phone simultaneously. When a call comes in, the headphones can identify which paired device is ringing and connect to the appropriate device automatically. You can also switch between the two connected devices at the touch of a button.
Fast Pair and Swift Pair provide additional options for easy connection, while simple button operation makes controlling the headphones straightforward. The headphones can also be controlled using your voice.

Clear Calls
Taking calls with the WH-CH520 is designed to be straightforward. You can answer calls with the press of a button, while noise suppression technology helps provide clear call quality during conversations.
