Review on Upgrade Your Studio Gear with Audio-Technica ATH-M40x Professional Studio Monitor Headphones: 90-Degree Swiveling Earcups, Pro-Grade Earpads/Headband, and Detachable Cables by Chong Eun Moon ᠌

Different pros: Detailed sound. I can hear the inferiority of Mp3 files. Long, detachable cables (They "wrap" to the headphones and cannot be torn off). Very good build. No jambs, no backlash, strong. Has cons: Ear cushions: You need to get used to them, but on the whole they are comfortable, and after six months of use they were worn out in places, because. leatherette Pressure on the head: The headphones put a lot of pressure on the head. After a few weeks you get used to it, but sometimes you really want to take them off. (some people wear them over something wide to fix this). They themselves do not "break in" (plus assembly). Some may not like the bass.
