The LED indicator will show charging status and turn off when fully charged. A full charge provides up to 70 hours of playtime.

2. Powering On/Off
- To Power On: Locate the power button (often a slider switch) on the earcup. Slide or press and hold the power button until the LED indicator lights up and you hear an audible prompt.
- To Power Off: Slide or press and hold the power button again until the LED indicator turns off and you hear an audible prompt.
3. Bluetooth Pairing
For first-time pairing:
- Ensure the headphones are powered off.
- Long-press the power button until the LED indicator flashes rapidly (usually blue and red), indicating pairing mode.
- On your device (smartphone, tablet, computer), enable Bluetooth and search for available devices.
- Select "9S" (or similar name) from the list of found devices.
- Once connected, the LED indicator will stop flashing and remain solid blue, and you will hear a confirmation sound.
The headphones support connecting to two devices simultaneously. 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 headphones should connect to both.
