      Clayton BryantJul 26, 2025
      If your Jensen Speakers aren't producing any sound, several factors could be at play. First, the battery might be dead, so try recharging it. Ensure the speakers are properly connected to your device via Bluetooth by going through the 'Operating the Unit' process. Also, make sure the speakers are within the Bluetooth operating range (30 feet). Lastly, the volume might be too low, so press the Volume + button to increase the sound level.

      If your Jensen Speakers aren't charging, ensure the USB power adapter is correctly plugged into a functioning wall outlet and that the USB cable is securely connected to the mini USB jack on the SMPS-640. To verify the wall outlet's functionality, plug another device into it. If you're using a computer USB port, confirm that the computer is powered on and try a different USB port.

      If the sound from your Jensen Speakers is distorted, try decreasing the speaker's volume. The distortion might also originate from the sound source itself; if the audio file is low quality, try playing a higher quality file. You can also try turning bass boost OFF or change the EQ setting. This can contribute to distortion on some speakers.
