Query: Good sound, poor durability

I purchased these in August 2007, and was initially pleased with them. Reasonably good sound and comfort. However, one side completely dropped out after a few months. Ultimate Ears replaced the earbuds, and the replacement pair just failed today - they lasted about a year. Bottom line: good sound, good comfort, good customer service, lousy durability. I don't think I'll venture down this road again.
