Never having spent more than $30 on earphone before, in May of 2010 I bought a pair of $70 Sennheiser earbuds. Up until this week I had absolutely no problems with them, but for whatever reason one of the sides blew. I called the store to see if by some miracle they had an in-store warranty and if I could replace them or repair them, and they did! Since they took my contact info when I bought them, I was able to exchange them for a new pair without a receipt, no questions (beyond "whats wrong with them?") asked.
