Hi all,
I bought HDJ-2000 a week ago and I would like to share a couple thoughs, maybe a review later on:
context:
- these are DJ headphones, the flagship product of a line of DJ gear where Pioneer very very very VERY BIG
- ... this means they did not really care how this would sound with classical music (duh!)
- .... but we should take them for what they are but not by their 'DJ' credentials, they are much more than boom boxes.
- bass is there but a bit 'hollow': doesn't "booom", more like "ummmm" (hope you get what I mean)
- no matter what you throw at them they will never hurt your ears (sound-wise) no matter how loud you play them with 'hot' or sibilant recordings, even from an ipod, I definitely get the feeling they are protecting my ears (regarding the bass I also never get the feeling they are trying to bomb my eardrums like some other headphones, remember, "ummm" not "booom").
- they were made to be played LOUD, so at low volumes they sound a little 'murky' like Tyll said on inner-fidelity
- overall sound is "smoothed" and not revealling, great for bad quality music or poor/portable sources on noisy environments, bad for critical listening or studio monitoring.
- build-wise I think they will last a lifetime!! top!
- huge benefit from amping (bass is deeper and more controled, mids come out a little more)
- they have 'groove' but feel laid-back, almost sennheiser-like (for which the the energy is in the high-mids, not in the bass like the Pioneers)
- what they don't have is 'zing' and bite for guitars for instance or delicacy for classical.
overall: if you are looking for sennheiser-like revealing mids, forget it - use TMA-1 from AIAIAI (mids are more revealing but is more like a tool, not pleasurable to listen to me at least). Use the Pioneers for what they are and you will be very happy - portable, top build quality, good isolation, protects your hearing at high volumes and sound good with no fatal flaw.
They don't anything exceptionally well.... except the fact that they don't do anything wrong! whitch is quite an achievement! For a portable alternative they're a fine choice, as a reference for home not really. However they are far far far better overall than their 'DJ' credentials would lead you to believe: although murky/laid-back sounding they are pretty balanced.
hope this helps, will make a more coherent text when I get the time
PS: I need to add that mine have little use yet, some of this may change over burn-in.
