Well, he was DJ'ing pretty heavily with his, so it doesn't surprise me that he had more trouble. Unless you need the wacky pivoting ear-pieces for DJing I think the 7506 model is probably a good bet. Bay-Bloor Radio also has a huge wall of headphones all running through a single cd-player.. so you can pop in a cd and then compare various brands/models. It's pretty sweet. Personally I found most of the Sennheisers/Grados/etc pretty uncomfortable, physically... The Sony's were quite comfy though, and also sounded pretty good to my somewhat destroyed eardrums.
