I have the TMA-1's, HD-25's and Pioneer HDJ-2000 2000's are easily the most comfortable around the ears, they are a bit heavy though. I leave these at home to use on the comp for music/gaming sessions. HD-25's are the easiest to carry around and are the lightest, they also provide very good isolation but sometimes can get a bit uncomfortable with the clamping force. The portability and durability of these cans make them the ones I bring to my gigs/sets. TMA-1's, a bit bigger/heavier/bulkier than the HD-25's but not as much as the 2000's. Easiest to drive and so I keep these in my work bag and use them on the train and at work. Sound wise, all 3 are pretty damn good. On a comp/mp3 player/mobile phone the TMA-1's sound the best (easiest to drive). Through a proper mixer, in a club environment the HD-25's provide the punchiest bass and handled louder volumes the best. Pioneer lacked bass the most and couldn't handle higher volumes as the other two, but it doesn't mean it's a bad headphone - just not up to par with the other two.
