Query: GREAT and their warranty service is great !

Well- economical earphones like this.. what can we expect? It's a decent product but only lasted 4 to five months -- But they have this one year warranty service and they've sent me the new products twice when mine broke or started not working. It's easy - just register your product in their website and claim warranty for the product registered. They send you the exactly same, new one as you purchased.
