Comfort - 10 out of ten, working on a radio station I wear these headphones up to 8 hours a day, I dont event notice these.
Sound Quality, I have seen negative reviews about stereo fielding and bass response, It isnt amazing, but lets not forget theres are mid-range, the fielding is fantastic on the tracks I tested including an orchestral arrangement and drum solo. Bass response, it is there, if the song has bass! I checked this with both the prodigy and chase and status, and believe me if the bass is meant to be heard, you hear it! The audio output is crystal clear, speech is brilliant, drums play crystal clear. I have a recording of a led zep track, these cans are so clear you can hear a musician changing the page of their song book......beats by dre cant produce that sound!
Style - you will look like an space man but for the output, its worth it, if you want to look good in headphones, beats by dre - if you care about quality first and foremost...AKG
Extras - mini xlr connection so handy if like me you step on the cable a lot you wont pull it out, Screw jack converter - not noisy and secure. Auto-muting, a cool extra and so useful if you are recording or live on air and take your cans off you wont ruin anything. Choice of two cables, coiled or straight....all ways nice, choice of pads - felt or leatherette again nice to have the choice, i fin leatherette comfier. Self adjusting headband increases comfort to a high level.
I really recommend these headphones great all round quality for an unbeatable price!
