Soundcore Life Q10 headphones. I bought them years ago and they've become old and worn out. Their specs claim up to three days or more (60 hours in the description). I used to charge them infrequently, and their sound isn't very loud, but it's decent, honestly not bad. They connect to two devices and work well. The only issues are that there are no accessories and the ear cushion fabric has torn from use. (Performance-wise, they haven't changed at all since I bought them. The only negatives are they're a bit broken on top, the ear cushion fabric is torn, and whoever buys them can buy new foam cushions and refurbish them.) Reason for selling: They are among my best headphones, but I bought a better pair, so I don't need them anymore. I'll lower the price for a serious buyer.
