To make sure the charging issue is not a result of a faulty cable or charging source, please test using another cable as well as an alternate charging source (for example - if you're using a computer USB connection, try a wall charger instead).
If using alternate charging methods does not work, there are a few other things we can try.
1. Cycle the MW65 power OFF and then back ON.
2. Turn the Bluetooth® OFF, then ON again on the source device.
3. Turn OFF the Bluetooth feature on any other device that is paired with the headphones (phone, computer, etc.).
If the above steps do not resolve your issue, please try a factory reset.
If you're still experiencing charging issues after completing the factory reset, please submit a ticket, and one of our representatives will be able to assist you further.
