If the picture is the actual product then these are the full blown '25s as the cut down version lacks the single sided cabling, which is designed to make them more dj friendly (although the single cable is on the right side which is actually the wrong side for many mixers which have the headphone output on the left).
Whether mk1 or mk2 the price is fantastic for industry standard cans, you will see these used by soundmen, tv reporters etc the world over and for very good reason. The sound is incredibly clear, neutral and balanced, they also go much louder than consumer grade cans would dare and do not lose any of the finer reproductive qualities when pushed. The silence when putting these on is uncanny and they are very comfortable to wear for long periods and despite their monitor design are very enjoyable to listen to, but will ruthlessly show up any deficiencies in the source or playback device. They are not really mp3 player fones but my Zen can drive them to listenable levels (just) which it can't with my AKG 181's, to be frank though these would be wasted listening to mp3 and when doing so it is easy to hear the limitations of the compression, even at 320kb CBR. Recommended to anyone who takes their music seriously and doesn't want to have to upgrade, ever! To really hear what these can do I would suggest listening to a dvd through them and if you have PowerDVD and a half decent soundcard then try the Dolby Headphone setting, it will blow you away. I first experienced this with Channel 4's Green Wing and had to keep checking that I hadn't left my surround system on.. :D
