I had a pair of Sennheiser CX200's, and I loved them dearly. I got them on sale for $15 or so from Newegg, and they're easily the best in-ear headphones I've owned. One of the lines died on mine a few months ago, though, so I threw them away. They're on sale again on Newegg for $20, and I'm tempted to buy them, but I don't want another pair that dies (from research and experience the CX200's seem to have a nasty reputation for lasting less than 6 months before dying).
So my question is, are there any alternatives that sound similar or better for around the same price range? I'd like to keep it under 30 USD.
