Back to Top - My Avantree Quartet Headphones won’t charge. Why?
If your headphones are not charging, please try using different USB cables or different USB charging blocks to charge the headphones. Also, try using different wall outlets in your house to see if that fixes the problem.
If your headphones still won't charge, it is possible that they are damaged. If your product is under warranty, contact us and we will replace it free of charge.
Just a warm reminder, please do NOT touch ⑥ AUX Input Port when you charge the headphones with a USB cable. The human body has static. If you touch the metal of the AUX port with your bare hands while charging, that might damage the headphones.
