Sony WH-CH520 Wireless On-Ear Headphones - White

DSEE (Digital Sound Enhancement Engine) is a Sony technology that restores the high-frequency sounds and fine fade-out sounds that are often lost when digital music is compressed. This results in a more natural and authentic sound experience, making your music sound richer and more detailed.

Yes, the Sony WH-CH520 headphones feature Multi-Point Connection, allowing you to connect to two Bluetooth devices simultaneously. This means you can seamlessly switch between, for example, your smartphone and your tablet without needing to re-pair.

The headphones offer an impressive battery life of up to 50 hours on a full charge. They also support quick charging, giving you 1.5 hours of playback from just 3 minutes of charging.

Absolutely. The WH-CH520 headphones are equipped with a high-quality built-in microphone and noise suppression technology, ensuring clear voice transmission during your phone calls, even in moderately noisy environments.

No, the Sony WH-CH520 Wireless On-Ear Headphones are not waterproof. Please avoid exposing them to water or excessive moisture to prevent damage.

Use a soft, dry, lint-free cloth to wipe the earcups and headband regularly. For light marks, you can slightly dampen the cloth with water. Avoid using strong detergents, alcohol, or abrasive cleaners.

Ensure the USB-C charging cable is securely connected to both the headphones and a working power source. Try a different USB port or wall adapter. Allow the headphones to charge for at least 10-15 minutes before attempting to turn them on again. If charging via computer, ensure the computer is powered on.

Make sure the headphones are in pairing mode (indicator light flashing rapidly). Ensure Bluetooth is enabled on your device and it's within range. Try turning Bluetooth off and on again on your device. Delete any previous 'WH-CH520' entries from your device's Bluetooth list and try pairing from scratch. Restart both the headphones and your device.

Ensure your audio source (phone, tablet) has good signal strength and is not too far from the headphones. Check the audio quality of the original file or stream. Make sure the volume is not set too high, causing distortion. If using a custom equalizer, try disabling it. Ensure there are no physical obstructions between your device and the headphones that might interfere with the Bluetooth signal.

Ensure both devices you wish to connect are actively paired with the headphones. When switching, pause media on the first device before starting on the second. For calls, ensure the call is picked up on the device connected to the headphones. Sometimes, temporarily disabling Bluetooth on one device and re-enabling it after connecting the second can help reset the multi-point connection.

Ensure the microphone is not obstructed (e.g., by clothing). Check the microphone settings on your connected device to ensure the headphones are selected as the input device. Move to a quieter environment if possible, as noise suppression works best on consistent background noise rather than sudden loud noises. Ensure the headphones are positioned correctly on your head.
