I agree about the w4 but really once you have them for a while you start to really love them,, specially when you put something else in your ears after ,, it's kinda like ,, ewwww lol just my opinion. And toe the ie80 is fantastic I drive them with my continetal v3 and they really shine even more. They are kinda layed back but with a lot of dynamics. Hope that makes sence. Lol which ones would I sell first my ie80 or my w4r's?? I'd still have to say how good they are ,, my w4r's. don't think I'd ever get rid of my senns
