Connectivity
Bluetooth Connection

- Store the headphones in a cool, dry place away from extreme temperatures and direct sunlight.
- Avoid dropping or subjecting the headphones to strong impacts.
- Do not attempt to disassemble or repair the device yourself. Contact customer support for assistance.
