These headphones retail at $970 on online stores. These pairs are mostly used for top of the line artist in studio recordings.
I have tried these on and listened to a few songs. These have to be the best headphones that I've ever used. The noise cancellation is amazing and the quality is stunning. The sound definition is so good that you wont feel controllable buying any other headphones. The bass is rich and able to remain the best in quality for any type of music.
Here are the tech features:
Equipped with detachable cable with locking mini-XLR connector
Soft genuine leather headband and cushy 3D velvet ear pads
Frequency range 10 to 39,800 Hz
Cable 3 m single-sided (99,9% oxygen-free)

I would recommend the AKG K702 Headphones to anyone who is looking to start recording their music. You can buy them here from amazon here: http://adfoc.us/126812014625
