JBL 510BT headphones won’t turn on or off; how can I fix this problem?

If your JBL Tune 510BT headphones are unresponsive to power prompts, a factory reset may be the solution.

To do a reset, turn on the headphones, then press and hold the Volume Up (+) and Volume Down (-) keys for more than 5 seconds. The LED indicator should flicker, indicating a successful reset.

After resetting, try turning the headphones off and on again. If they still do not respond, connect them to a charger with a verified working cord and power source. Allow them to charge for at least two hours before attempting to power them on.

If these methods fail, inspect the power button for any physical damage or debris that may be preventing it from functioning properly.

If the button is intact but the headphones still do not respond, the problem could be hardware-related. For more assistance, please contact JBL customer care. JBL provides a live chat option and email support through https://support.jbl.com/us/en/customer-service/

If the problem remains unresolved, consider filing a complaint on Xolvie to raise awareness about the issue and inform others.
