I originally had a pair of DCs but found them uncomfortable (clamping force wise) after about 45 minutes. I sprung for a new pair, can't remember the model number but the ones with adjustable clamping force. Added a thirdparty ANR kit. They were marginally more comfortable, but not much. After a ten day several hours a day trip across the US and back under a pair of Bose-X I decided to spring for them. I think Bose-X stuff is hugely over priced (they have great marketing) and the quality of their music systems is low, but this is by far the best headset I've ever tried. It is super-comfortable, works well with my spectacles and the ANR works very well. If you can afford them I wouldn't worry about trying them out - you will like them.
