Begin at a low volume

Use dry earbuds and set a low volume before putting them in your ears. Test tones can feel louder than ordinary music.

Step 2

Identify each channel

Play the alternating left and right cues. Note a missing side, incorrect channel or obvious level difference rather than chasing a perfect match.

Step 3

Swap the source

Use a second phone, laptop or cable when possible. A problem that follows the earbuds is more likely to be in the earbuds themselves.

Step 4

Inspect and escalate safely

Check the mesh and connector visually. Persistent silence, overheating, battery swelling or water exposure calls for manufacturer support or qualified service.

The short answer

Check the mesh and connector visually. Persistent silence, overheating, battery swelling or water exposure calls for manufacturer support or qualified service.
