My right AirpPod Pro resonates weirdly in my ear during conference calls. It’s especially bad when I am speaking. When others are speaking it depends on their voice and the effects can be mitigated by repositioning the AirPod in my ear. When I listen to music it sounds fine. Cleaning with a brush improves the situation temporarily (for a day or so). Any suggestions for what it could be and/or a more permanent solution?
