      There could be several reasons why your Jensen Speakers aren't producing sound. First, the battery might be completely drained, so try recharging it. Second, the speakers may not be properly connected to your Bluetooth device; in this case, you should pair your device with the speakers again. Third, the speakers might be out of range; ensure they are within 30 feet of your device. Finally, the volume might be set too low; increase the volume using the Volume + button.

      If your Jensen Speakers aren't charging, there are a few potential causes. Ensure the USB power adapter is properly plugged into a functioning wall outlet and that the USB cable is securely connected to the mini USB jack on the speakers. To check if the wall outlet works, plug another device into it. If you're using a computer USB port, make sure the computer is on and try a different USB port.

      If the sound from your Jensen Speakers is distorted, try these solutions: first, decrease the speaker's volume. Second, the audio source may be of poor quality; try a different audio source, like a music CD. Finally, if you're using an external sound source like an older iPod, reduce the output volume on the device itself, and try turning bass boost OFF or changing the EQ setting.
