Grado makes some rather interesting headphones, and I heavily have a soft spot for them. They treat your ears to an open clean window along with a prominent midrange. This makes well recorded music sound alive and damned communicative.
Steve's video is interesting. Must say I do agree with him.
Don't worry chaps I'm not bloody shilling for the brand!
