These things are amazing. The sound is absolutely mind blowing. Playing games wearing these really put you in the game. Music is crisp and clear and base can be felt in your bones. One of my favorite things about them though is that you really have no bleed out from the headphones. If you keep them at a moderate volume no one else can hear what you are listening to. They are very durable and I now own three pairs for various locations. The cord can be a bit long but if you play guitar (or other instrument) you can sling it around your back and run it past the back of the equipment to keep the cable out of the way. 

Question: How is the quality on the audio?
