Follow these steps to pair your headset with a Bluetooth-enabled device:
Dual Device Connection: The headset supports simultaneous connection to two Bluetooth devices. After pairing with the first device, disable Bluetooth on that device, then pair with the second device. Re-enable Bluetooth on the first device, and the headset should automatically connect to both.

The main controls are located on the earcup:
During a call, press the dedicated Mute button on the earcup to mute your microphone. Press it again to unmute. The headset will provide an audible confirmation (e.g., "Mute On" / "Mute Off").
To switch between the three available music modes (POP, Bass, Vocal), double-click the Multi-Function Button (MFB) while music is playing. Each double-click will cycle through the modes.

A full charge takes approximately 2 hours and provides up to 35 hours of talk time.
