Technics RP-DJ1210 Professional Headphones

I was told to purchase these at the DJ/Music Production class I am attending in Farringdon. The teacher said that they where the best on the market for DJing. I recieved a pair from an ebay shop for £90 delivered. As I can not compare them to anything else as these are the first pair of decent headphones I have bought but I can say they have a real good sound and compared to the cheap sony MDR 100's they produce much more sound from my walkman and much better. The bass is very good and the full range in fact seems very nice. Using it with my DJ equipment I can really pump out a loud sound on these heaqdphones without damaging them. They also have a good cushioning system which gets a bit hot around the ears but really stops a lot of back ground noise entering.
Like I said i have nothing decent to compare them to but compared to my cheap headphones it is truely in a league of its own. Oh plus they have swivel arms so you can place one or both the heads above your ears which is useful for DJing.
