I personally have had the same experience as EndlessWaves, many of my headsets have broken down. My friend also had two of the Razer headsets destroy themselves internally, and they are like £70 each or something crazy.
Maybe they don't like my crazyness then, I spent £70 on the zalman theatre 6 headset when it came out, and it lasted about six months before the connection to the headset came loose so I got it replaced and the replacement lasted about seven more months. I then got a set of the original medusas for about the same price. Nice headset but I had the headband on them snap completely after the best part of a year. Then I decided to go for a pair of icemat audio siberias, I think they were about £50. After about a year, year and a half, the volume control unit went all crackly. It looked to be sealed but it was detatchable so I replaced it with an extension cable and then recently the headband came off and the sound quality has degraded noticibly.
I think my next set will be some Audio-technica ATH-AD700s for around £90, unless anyone can recommend some durable headphones. Although I am tempted to get these as a stopgap measure since they're cheap and hopefully better than the broken siberias (has anyone compared them to a set of siberias?)
