Generation 2 Airpods do not fit after 1.5 years of use

I noticed a month or so ago that my Gen 2 Airpods dont fit in my ear any longer. I thought the sound was turned all the way down. I cleaned the speakers and have to hold them in my ears to achieve the sound quality i was getting the first 1.5 years. I tried silicon covers and still cannot. Is anyone else having the issue? Is it my ear changing or is it the actual material in the Airpods losing form and not fitting any longer? Im at a loss here. I could use the volume at slightly less than half and they sounded amazing! Now they sound terrible due to the deal not forming.

On a side note I also lost the ability to sync in stereo sound when using both pods. I can only use one at a time. Anything here as well?
