Bass distorts every song, just started.

I really do love the sound bag. What a great idea, and I use it alot, that is until about a week ago. It started distorting all the songs. Even when I had the volumne of my MP3 on 1, it still distorted the song. I did email Cluthfield, but never heard anything back. What can I do to remedy this? I feel that it should have lasted longer for the money. And, no, it was never dropped. I keep it clipped to the side of my purse.Please, advise me what to do. I do want the bag, but I think I should receive a new one.Thank you, Debbie Kelly750 Washington AvenueNiles, Ohio 44446Let me know how to return this for another.Thank you.
