Great Battery Life, but left earbud not working after a few days

The battery life is amazing, this thing works for multiple days without needing a charge, and you can even use it while it is charging. However, the left earbud is not working after less than a week of use - and get this - it stopped working while I was sitting in my chair not touching it. I heard what sounded like an electrical short through it, and then it stopped working completely. Very shoddy - definitely not working $50, I wouldn't pay $10 for something that doesn't work for an entire week.
