Ah, that makes sense. I loved my wired pair because I sometimes forgot to keep my wireless charged, and they had a tendency to be low on charge when I needed to be on important calls. They were my backups and the audio quality was also pretty good.

My current pair of wireless, that I use when exercising, has also stopped turning ON for reasons I don't follow, so I'm understandably miffed at having to listen to ambient noise during exercise.

It seems to me that we'll continue to have these issues as long as we have non-removable-battery earphones, since many of the issues come from having an independant power supply and firmware components.
