BT5.0-Audio PRO Bluetooth 5.0 Stereo Audio Receiver

Product detailed description

The BT5.0 Audio PRO continues the M28's excellent core features (long distance transmission, Bluetooth 5.0 backward compatibility, lossless audio quality, etc.) and adds more user-friendly features - Charging on playback: this product has a charging circuit that can directly charge the battery via a USB power supply, while still allowing it to continue to function normally during the charging process. This solves the problem where some products cannot be used during the charging process.

As an additional improvement, the indication of various states has been improved - When powered from USB: The red light flashes. When powered by battery: a yellow light indicates sufficient battery voltage and if the light is flashing it is a signal that the battery is low. When the USB and battery are connected at the same time: the red light flashes to indicate that the battery is charging. If the red light is on, the battery is fully charged. (If the USB input is suddenly disconnected during the charging process, the module will be interrupted for a few seconds during which the Bluetooth will automatically restart, automatically connect and maintain the previous playback state).

Incoming voice call function: when connected to Bluetooth, turn on the call sound mode in Bluetooth settings. You can answer or hang up an incoming call using the PLAY/STOP button. You can choose whether to use the headset microphone connected to the headphone jack (Microphone Jumpers. Assuming the headset has a call function, which is a 4-segment type), or from the module's integrated microphone (default). Use as a sound card for PC: Connect the module to the computer's USB interface using a USB cable and then it can be used as a sound card (Sound Card Jumpers).
