Setup
1. Charging the Microphone:
Before first use, fully charge the microphone. Connect the included Micro USB charging cable to the microphone's charging port and to a 5V USB power adapter (not included). Ensure the adapter is rated at 20W (5V) or less to prevent overload protection from interfering with charging. The charging indicator light will turn off once fully charged.
2. Powering On/Off:
Press and hold the power button (usually the central button) for a few seconds to turn the microphone on or off. A voice prompt will indicate the power status.
3. Bluetooth Connection:
- Turn on the microphone. It will enter Bluetooth pairing mode automatically.
- Enable Bluetooth on your smartphone, tablet, or other compatible device.
- Search for 'Q37' in the list of available Bluetooth devices and select it to pair.
- A voice prompt will confirm successful connection.

4. Cable Connection (AUX):
Use the included audio cable to connect the microphone's 3.5mm jack to the audio output of your device. This allows for direct audio input without Bluetooth.
5. Micro SD Card Usage:
Insert a Micro SD card (up to 32GB, not included) into the designated slot on the microphone. The microphone can then play MP3 files directly from the card. Use the control buttons to switch songs.
