Had one fall out onto my patio last week and since then my ANC feels noticeably worse, but at around this time the firmware updated without me realising that I’d left everything connected for it to do so - so it’s hard to be 100% sure that the drop was the cause. I HATE 8B39 either way, the changes to the status lights do my head in. Otherwise, the drop left a tiny mark on the AirPod.
Sometimes I feel that the ANC is only working on the AirPod that stayed in - but then the noise I want blocking is on the right where I usually use them and it was the right AirPod that fell out so it may also be in my head. There has also been a hairline crack in that stem for some time now which I’ve noticed has worsened.
I have AC+ because I gave myself a fright when one fell out onto carpet the day I got them - may be worth considering if you’re still in the window to add it.
Thinking I’ll send it/them in under AC+ when Summer’s over as I use them less in Autumn/Winter anyway - but not sure what to send them in under at the moment as the battery has also felt pretty rubbish for the last month.
