Thanks for reaching out. Here are some things to try that often fix these issues.If you have other charging cables, give them a try. (Be sure that the cable has the same type of connector as the original one that came with your product.). Same for the charger- if your product charges by USB, try a different USB charger. Be sure that it is rated at least 2.0a (2 amps) output. Try other electrical outlets at your location to be certain it is not a local wiring issue. Charge the product overnight for at least 8 hours. Sometimes wiggling the connection restores charging power. Access the link provided if you need further assistance. https://bit.ly/2WocMfi

Our JBL Tune 500BT has a built-in microphone. Please make sure that you've selected the headphones as the audio input and output on your computer's audio settings. We would also suggest checking the audio settings on the app that you're using.

Please try the steps and recommendations on our support page article about Bluetooth troubleshooting and Connecting, to isolate the issue with your Tune 500BT. https://support.jbl.com/us/en/
