I LOVE listening to music on these cans!  However, I can only do so when home alone it seems.  As with all open phones they can produce quite a bit of sound outside of your ear.  Music has a wonderful punch and brightness when heard through these, and they are very easy to drive without a headphone amp.  I would certainly purchase another pair of Grados in the future!

Overall I have been satisfied with these phones.  I would not recommend paying full price for them like I did.
