What's with the 500 exclamation marks in your thread title, OP ? THAT'S ALMOST AS ANNOYING AS SOMEONE SHOUTING AT ME WITH THE CAPS LOCK on. Please bear this in mind for future threads.
Grado make great cans in your price range, but I'm with the earlier poster - having owned the DJ1, they make more sense for electronic music and will give you (significantly) more isolation and bass impact. at the cost of the air and resolution of the Grados. If you can imagine listening to music while still being able to hear everything around you - traffic. conversation. crickets chirping - that will be your experience with Grado phones. Cranking them up is the last thing you want to do - that's where some models wait with an icepick of HF to stab you in the brain. The DJ1 is a colored phone, but I dont recall any icepicks.
