I wonder if the quality of Trekz/Aftershokz bone-conductive headphones is decreasing?
I've used them for ages, as has Sandra, and we have had multiple pairs.
The charging port on Sandra's last pair just feel apart. So we replaced them.
Now, something has happened to the lefthand bud of mine, so that it rattles.
I definitely use them a lot - every day - but it is still annoying.
@neil I use mine for sleeping and they last me about three years. The issue vary but I have seen both of the things you mentioned on recent (USB-C) models in this household.
