Sony WH-CH Wireless Headphones - Black

Turn on the headphones; they should automatically enter pairing mode. Go to your device's Bluetooth settings, select 'WH-CH520' from the available devices, and confirm the connection.

Yes, the Sony WH-CH520 features Multi-Point Connection, allowing you to connect to two Bluetooth devices simultaneously and switch between them seamlessly.

The headphones offer up to 50 hours of listening time on a full charge. A 3-minute quick charge can provide approximately 1.5 hours of playback.

The Sony WH-CH520 headphones feature noise suppression technology for the built-in microphone, which helps to make your voice clearer during calls. They do not have Active Noise Cancellation (ANC) for listening to music.

Yes, they are designed with an adjustable headband and soft earcups to provide comfort during extended listening sessions.

You can answer incoming calls by pressing the dedicated button located on the earcup of the headphones.

DSEE (Digital Sound Enhancement Engine) is a Sony technology that restores high-frequency sounds and fine fade-out sounds that are lost during digital audio compression, aiming to deliver a more natural and authentic sound experience.

Ensure the charging cable is securely connected to both the headphones and a functioning power source. Try a different USB-C cable or power adapter. Allow the headphones to charge for at least 10 minutes before attempting to power them on again.

Make sure the headphones are in pairing mode (usually indicated by a flashing blue light). Ensure Bluetooth is enabled on your device and that the headphones are within close proximity. If previous pairings exist, try 'forgetting' the device on your phone's Bluetooth settings and re-pairing. Turn off and on both the headphones and your device.

Ensure there are no obstructions between your device and the headphones. Move closer to your paired device. Check if other Bluetooth or Wi-Fi devices are causing interference. Try restarting both the headphones and your audio source. Disable DSEE in the Sony Headphones Connect app if you suspect it's causing issues (though this is rare).

Make sure the microphone is not covered by clothing or your hand. Check the volume settings on your connected device. Ensure you are speaking directly towards the microphone. If in a very noisy environment, try moving to a quieter location.

Ensure both devices are paired and within range. Audio priority is typically given to the device currently playing media or receiving a call. Manually pause playback on one device to switch to the other. If problems persist, try 'forgetting' the headphones on both devices and setting up Multi-Point Connection again carefully.
