About a year and a half ago I bought a pair of Sennheiser HD 202 Headphones  for a cool $20 that I could wear at work to listen to music. Overall, the sound quality was good and I was satisfied with its performance until a month or so ago when one of the ear’s stopped producing. Now, I’m pretty sure it was just the wire coming loose but I didn’t really want to break open the ear piece and try to sodder it back on. Since the Sennheiser HD 202 Headphones come with a two year warranty, I just printed out a letter, the invoice, and sent them back at a cost of like $4.00.
One week later, Sennheiser had sent me a brand new pair of my el cheapo $20 headphones no questions asked. I doubt they even checked that the originals were busted in the first place. I give them a thumbs up for customer service!
