One Side Sound / Louder. How to Fix it?
We found that a large proportion of one side sound or one side louder issue was caused by earwax blocking the ear tips. In this case.
- Take off the ear tips and clean the earbuds.
NOTE: If the earwax sticks on the speaker mesh and hard to remove, please avantree customer support for a new pair of speaker meshes to install.
- If the problem persists after cleaning the earbuds, please try to reset it. Press and hold the volume + and - buttons simultaneously for about 10 seconds until the LED briefly lights up RED & BLUE at the same time (may look PURPLE), indicating that the headphones have reset.
If it's still one side sound, pls contact avantree customer support for a replacement.
