Query: S9 Motorokr Headphones

I've owned my headphones for a little over 13 months. They worked fine until last week they stopped charging and won't turn on. Motorola's warranty expires at 12 months so I'm on my own with this. I did like being able to go wireless, but will not buy another product that fails so quickly and without support. I recommend looking elsewhere.
