Query: Perfect, but they've got one flaw

These headphones are insanely durable and have held up great. I've owned them for a year and I've gotten more then my moneys worth. The sound quality is great and sometimes I prefer them over my speakers.The only problem is that the rubber padding starts to wear if you use them a lot over the period of a year. Mine started as a small break in the rubber and has turned into a big chunk dissapearing. But I have really used these a lot and beaten them up quite a bit. So I'm only taking a star off, you can't beat the price and quality.
