These Sony headphones are totally amazing, from the low bass to the high treble they are superb, crystal clear sound as promised, does what it says on the box "3D SOUND". Don't hesitate, go and buy these headphones NOW!, very comfortable to wear over long periods. To get a even better sound upgrade the supplied optical cable, the reward will be an even better sound that i did'nt think was even possible but it is. A true bargin at PLAY.COM, my local hi-fi store sells these headphones for over 200 pounds!!, go on guys - treat yourselves!!!
