Ultrasone Pro 900 Balanced - Page 2

Sorry for the bump.

But I was doing some searching on the interwebs about headphones and what not, and so I came across these bad-ass headphones on iHeadphones.

http://www.iheadphones.co.uk/ultrasone-pro-900-balanced.html

Now this was the first time I saw the PRO 900's with this type of modification and I gotta say, it looks quite impressive. They are now going for 350 pounds aswell, which aint that expensive at all so they look fairly interesting to me.

But I don't realy know what to expect from this? I'm not realy an audio expert so could any1 perhaps tell me what exactly the difference is between regular headphone cabeling and balanced? How great will the difference be in the sound quality?

Is there any1 here that has these or has had experience with these or other balanced headphones?

edit: Also just noticed that the cabels are detacheble and that they come with stereo plugged cables... which make 'em even more interesting.

What's the difference between the balanced and the (stock?) PRO 900?
