They definitely weren't expensive ones, maybe $25-30ish, but they'd lasted for 2.5 years, hundreds of sweaty exercise sessions (what they were used for exclusively), and many charges. I got far more than my money's worth. I'm guessing I hadn't sealed the charging port well, had a bunch of sweat in it, and then charged, causing an issue, or had water splash onto the charger interface since they were on the kitchen island when they fried. Isn't every pair of headphones suitable for exercise going to be Chinese though?
Cheap Chinese crap. Look like the Mopow (or something like that). Get what you pay for.
