I own the Grados, and while I was impressed at first, I find them them annoying now. The on ear design gets uncomfortable. The build quality feels poor. The sound is detailed, but a bit rough. I wouldn't say they are that bassy either. I think there are better headphones out there for the money. Good value in the US where it is a $100 headphone.
Keep in mind that the Grados are an open backed design (i.e. sound leaks, so others in the room will hear the music too and the headphones won't block out any external noise).
