One of the reason why the senns are so popular is because they are sturdy and have a clean and accurate sound.
From what I know dj's need:
durability (because they travel and headphones breaking and being replaced become expensive as well as using them a lot( moving the earcups around for mixing and such))
Isolation (so that the sound coming from the speakers or house doesn't interfere with their mixing and cueing the next song)
Comfort for long hours of use
Low distortion at high volumes.
Bass for cut through rhythm detection.
dj functional( able to have an earcup move)
What I have personally heard and have had:
Pioneer hdj 2000
scores well in all of those categories except bass extension. The bass is hard but doesnt reach low. It also needs and amp to be driven loudly but good out of dj equipment and also sound decent from an ipod etc . The durability s decent. Mine didnt break but I'm not a dj and havent used them for rigorous applications. I have heard the hinges can break but durability loses to the german maestro or the senns hd. I really love the look and sound of minus the very low bass. The sound is kinda dark but still detail and clear. More dark than the german maestro wich is slighty dark.
The headphone swivel on these headphones have proven to be almost useless for the dj
The isolation on these are also fair but nothing to really talk about. They do beat some in isolation but the leak a little and you can hear a little.
They were very comfortable
German maestro 8.35d
The bass extends really low but is not super strong or anything. The have a balanced sound but are very full sounding and slightly dar.k. The mids are kinda forward.
They are super durable and I would say that I have not seen a hp more durable than these period. They are not made for dj'ing but tick a lot of the boxes necessary for dj hp's. They isolate better than just about any hp as well. They dont let sound in or out. They also like the pioneers can go high volumes without much distortion but I would say the pioneers are stronger in that area. They are also more sibilant than the pioneers.
The headphones do not swivel but most djs dont really need that. They pull the earcup back. I would say that the sennheiser hd 25 II are better in that area because though they dont swivel the thin headband is more flexible.
They are pretty comfortable but can get sweaty and warm quicker than the hdj 2000's.
What I have researched.
The v moda leaks a bit but isolates fairly well. The bass is deep and stronger than all of these headphones mentioned. graphs show this. These are becoming popular for dj's but appear to me more for the consumer than the professional though it seems to tick the boxes.
The ultrasones i havent heard or researched that much but know that the bass is actually condemned in general by bassheads or praised by those who are tired of too much bass. So I dont see how those are practical for djs.
All I can say is that If I was a professional dj I would have two headphones. One for functionality and dependability (senns or germans) and one for looks and enjoyment that can also do the job. After all presentation shows you are serious about your craft and that would go to the Pioneer hdj 2000's(black) or Vmoda's. All four of them sound really good. My two would be germans and vmoda.
Sorry if i put too much here.
