I've had these headphones for about 4 years now and they continue to be my go to headphones. Not only do they do a great job of isolation, they also have a great sound quality. They are perfect for drummers who want to hear a click track both live and while recording. I've had a ton of drummers use them in my studio and I have heard nothing but how much they love these. They are also great for anyone recording in a studio that wants to use a nice pair of headphones. I have a few other cheaper sets of headphones and looked into buying a more expensive set (Sonys, Sennheisers), but I kept coming back to these. A few things I don't like however is the framing for them - although mine is still intact, it seems they could break pretty easily. Also, if you wear them for a long amount of time they can become uncomfortable but that really happens with all headphones for me. For this price I think you get a great deal for a very nice pair of studio headphones.
