I’d my Life P3 since end of September last year, loved them a lot. Though a couple months ago I noticed the fabric above the logo on my left earbud was damaged and had started to loosen up from the top - not sure how it happened if I accidently got my nail in there at some point, as time gone by though it loosed up more until it got total loose.
Beneath it is a thin plastic layer as well which now also had got loosen up, and sure the device still been working until recent week when I noticed the left earbud has a lower volume than the right.
Tonight I wanted to try solve it so, I been resetting, reconnecting as well tried with other apps and with another phone too but the issue remained.
Found it may be earwax inside it or something, so I was about to clean it and well… now it doesn’t make any sound.
Anyway, I been curious of another, L3P which I ordered today.
BUT, I still wonder what this hole behind is? and if that could have been the cause of the issue that the earbud had lower volume than my right earbud (it was noticable lower, but the ANC and stuff still seemed work as usual for both, but volume levels different).
So clearification is, I mostly just curious what that hole is and, if anyone else had this issue that the fabric (or whatever material) loosen up ?
even if i already also ordered a different soundcore earphones which anyway then if this fixed will have an extra and use for different purposes or places
