hd 650 headphones-take a trip-and love forever

i thought i had to write a review on these headphones , just in case anyone is in 2 minds to purchase or not and concerned about the cost.
Firstly the build is superb , the headband is fully adjustable and the ear pads feel comfortable , they actually feel even more comfortable once worn for a while, and after about an hour you dont even realise you have them on.
The sound , well its just astounding , from the moment you put on any cd its like hearing it for the 1st time, the detail is astonishing, and the depth and quality of sound is hair standing on end quality on some cd,s.
Driven with a good system they are the best up-grade on any system, and you can purchase better cables for them from a company called Kimber at www.kimber.co.uk.
If you love your music through phones these are a must buy.
