The Sony WH-CH520 Wireless On-Ear Headphones are designed for music enthusiasts who value authentic sound and seamless connectivity. Featuring the Digital Sound Enhancement Engine (DSEE) for restoring audio quality and Multi-Point Connection for effortless device switching, these headphones offer a versatile listening experience. While providing exceptional comfort and an impressive 50 hours of battery life, their on-ear design means they offer a different fit and level of passive noise isolation compared to over-ear alternatives, which users should consider.

Charging: Before first use, fully charge your headphones using a USB-C cable (not typically included). Connect the cable to the charging port on the headphones and a USB power adapter or computer USB port. The indicator light will change (e.g., turn off) when fully charged.
Pairing Mode: Turn on the headphones. Usually, they enter pairing mode automatically upon first power-on. If not, press and hold the power button for a few seconds until the indicator light flashes rapidly (e.g., blue and red alternately), indicating pairing mode.
Connect to Device: On your smartphone, tablet, or computer, go to your Bluetooth settings. Look for "WH-CH520" in the list of available devices and select it to pair. Once connected, the indicator light on the headphones will typically flash slowly or turn solid blue.
Multi-Point Connection: To connect a second device, disable Bluetooth on the first device temporarily, then put the headphones into pairing mode again and connect to the second device. Re-enable Bluetooth on the first device, and both should now be connected simultaneously.
The Sony WH-CH520 headphones are broadly compatible with any device that supports Bluetooth connectivity, including:
Smartphones (iOS, Android)
Tablets (iPad, Android tablets)
Laptops and Desktop Computers (Windows, macOS)
Other Bluetooth audio transmitters
Cleaning: Regularly wipe the earcups and headband with a soft, dry, lint-free cloth to remove dust and oils. For stubborn marks, lightly dampen the cloth with water. Avoid using harsh chemicals or abrasive cleaners.
Storage: When not in use, store your headphones in a clean, dry place, away from direct sunlight and extreme temperatures. Avoid placing heavy objects on top of them.
Moisture: These headphones are not waterproof. Keep them away from water, excessive humidity, and sweat to prevent damage.
Charging: Use a reputable USB-C cable and charger. Avoid overcharging the battery, though modern devices have protection against this, it's good practice to disconnect once fully charged if possible.
Handling: Be gentle when adjusting the headband or folding the headphones (if applicable) to avoid stressing joints or wiring.
