Overview
Key Features
The WH-CH520 has a Bluetooth multipoint connection, easy button operation and can even be controlled with your voice. Easy pairing with Swift Pair and Fast Pair, these Sony headphones are ideal for everyday use.
With a battery life of up to 50 hours, you can listen to your favourite music without worrying about the battery. If the battery of your headphones runs low, a 3-minute quick charge gives you 1.5 hours of listening to music.
The Digital Sound Enhancement Engine (DSEE) restores your music with high frequencies and gradually decreasing sound for a more authentic performance. With the EQ settings in the Sony Headphones Connect app, you can even adjust the sound to your own taste and create an individual listening experience.
Take calls with a click of the buttons on the ear cups without having to take your phone out of the case. Thanks to the high-quality built-in microphone and noise cancelling, the WH-CH520 records the sound and reduces ambient noise during the conversation, so you can have clear conversations even in noisy environments.
With the adjustable headband, soft ear pads and lightweight design, you can find the perfect fit for you, so that the on-ear headphones stay comfortable for longer.

Frequently Asked Questions
How long does the battery actually last on the WH-CH520?
Sony rates it at up to 50 hours on a full charge. If you run low, a 3-minute quick charge provides approximately 1.5 hours of playback — enough to get through a commute or workout in a pinch.
What is Bluetooth multipoint and how does it work on these headphones?
Bluetooth multipoint lets the WH-CH520 stay connected to two devices at the same time — for example, your laptop and your phone. You can switch audio between them without manually disconnecting and re-pairing.
Do the WH-CH520 have active noise cancellation?
The headphones feature noise cancellation on the microphone for clearer phone calls, but they do not have active noise cancellation (ANC) for music listening. They use an on-ear design without noise-isolating sealed cups.
What is DSEE and does it improve sound quality?
DSEE (Digital Sound Enhancement Engine) is Sony's audio processing technology that restores high-frequency detail lost during digital compression. It helps compressed streaming audio sound fuller and more natural without requiring lossless source files.
Can I customize the sound profile?
Yes. The Sony Headphones Connect app lets you adjust EQ settings to tailor the sound to your preferences, choosing from presets or creating a custom profile.
