Query: Not worth the trouble

I bought a pair of these in Sept. 0f '07 because Apple headphones suck and hurt my ears. I enjoyed these for the first few months, the sound quality was much better than my old ones and they were comfortable to wear for long periods of time. Then after about four months, the left ear stopped working unless I turned the cord a specific way and didn't move it at all, which was a pain. A few weeks later, the left ear stopped working altogether so I e-mailed the company for a replacement (they come with a 1 yr. warranty). Two months after I got the replacement, the left ear also died completely on that one. My FOURTH pair in under a year also just died and, despite the warranty being valid for a few more months, the company refuses to replace them anymore. These aren't worth the $20 they charge and there are others that are half the price with similar sound that last much longer. Don't waste your money or your time.
