Hi. I got a pair of SoundSport headphones in January. I don't have an extreme lifestyle (jogging a few times a week, I don't sweat a ton). The headphones died after three months. They just all of a sudden stopped working. Bose sent another pair, which I received 10 days ago. They just died, the same way: Working fine; I go to bed without charging them (they were almost fully charged); woke up; they aren't working. I think the odds of me getting two lemons are extreme, but I can't figure out what I might be doing incorrectly. The only thing I can think of is that I'm changing them through the USB hub on my computer. Is that a bad thing? If that practice isn't a big No-No, then I'm not sure what to do. I can try getting another pair from Bose but I'm very disillusioned.
