I have been using these headphones for about 1 year now. I went into a music store looking to pick up another pair of Sennheiser HD's, but I saw a pair of these out on demo and took a listen. They sound Great! While you can never really get a true feel for the bass with any headphones, this pair comes a lot closer to the sensation. The whole frequency range seems very even and clear, and doesnt seem to break up at higher volumes.

Perhaps the best feature that these headphones offer is the comfort of wearing them. I sometimes have sessions where I have to wear headphones for 8 hours at a time, and every other pair I've used get seriously annoying and give me a headache. But these are so well padded that it's like wearing a pillow - even though your ears are still fully enclosed. There's very little ear fatigue, and you don't get the persistent feeling of pressure on the side of your head that you get with extended use of other headphones.

They also provide excellent isolation, so I like to give these to vocalists singing in a booth, since there's going to be very little bleed into the mic. The other benefit is obviously that just using these to listen to music is quite nice, because it cuts the background noise by a lot. It also comes with a 1/4" adapter which allows you to plug in to audio hardware, and a very long cord. The cord is not coiled, which I appreciate, as those tend to get all snagged up. They are somewhat pricey, but definitely worth the money.

The only downside that occurs to me is that they are rather bulky - but who cares when they sound this good and they're this comfortable. These are my favorite headphones. They sound better and are more comfortable than the competitors like Sony and Sennheiser. I would absolutely buy them again, and I plan on getting another pair.
