Check balance and battery first
Confirm the left-right balance is centered, both AirPods are charged and mono audio is not changing the comparison.
Compare fit and source devices
Reseat both AirPods, try a different ear tip if your model uses one, then pair with another phone or laptop to rule out the source.
Inspect the mesh without pushing inside
Look for visible debris under good light. Follow Apple’s cleaning guidance and never insert a pin, cotton swab or liquid through the mesh.
Keep water and charging separate
If the AirPods or case are wet, let them dry fully before wearing or charging. A channel test can reveal a difference but cannot remove internal moisture.
