Enter Pairing Mode: With the headphones turned off, press and hold the power button for approximately 7 seconds. The indicator light will flash blue rapidly, signaling that the headphones are in Bluetooth pairing mode.
Connect to Device: On your smartphone, tablet, or computer, navigate to the Bluetooth settings. Select "WH-CH520" from the list of available devices to complete the pairing.
Multi-Point Connection (Optional): To use Multi-Point with two devices, first pair with device A. Then, turn off Bluetooth on device A. Put the headphones back into pairing mode and pair with device B. Finally, re-enable Bluetooth on device A. Both devices should now be connected to the headphones.
Bluetooth Devices: Compatible with any audio source that supports standard Bluetooth profiles (e.g., smartphones, tablets, laptops, smart TVs).

Cleaning: Regularly wipe the earcups and headband with a soft, dry cloth. For light stains, a slightly damp cloth can be used. Avoid abrasive cleaners or solvents.
Storage: When not in use, store the headphones in a cool, dry place. The swivel earcups allow them to be folded flat for compact storage, protecting them during travel.
Charging Habits: Use a reliable USB-C charger. Avoid completely depleting the battery for extended periods to maintain optimal battery health and longevity.
Environmental Protection: Do not expose the headphones to excessive moisture, rain, or extreme temperatures, as they are not designed to be water-resistant.
