Soundstage and detail retrieval can't be beat. Most comfortable headphone I've ever used. The sound signature is a bit bright with less bass impact than I would like, but I've found them to be very responsive to EQ. Those who dislike the default balance of these cans really owe it to themselves to listen again the help of some EQ, anaxilus mods, or careful component matching because when you get the tonal balance right you're left with a technological marvel. The biggest downside is the sheer amount of poorly recorded music that is borderline unlistenable under the HD-800's microscopic gaze.
I don't think many will argue that the LCD-3's have the best bass performance you can get in heaphones. You could describe the LCD-3's as smooth yet visceral. Slightly uncomfortable for me, but they are getting easier to wear as I adapt to them. They're more forgiving than the HD-800's, and easily the best cans for electronic music or the 'harsher' genres. I think the LCD-3s fall behind the HD-800s when it comes to the very best recordings though. When I switch from the LCD-3 to the HD-800, I find myself missing the low end performance and impact, but the increased detail and soundstage is more engrossing to me and I miss that more when I go back to the LCD-3. I enjoy the LCD-3 a lot more when I'm not comparing it against the HD-800. The reverse is also true to but to a far lesser extent. If only I could have it all!
The D7000 can make even the worst recordings sound good, very, very "fun." Technically soundstage isn't as good as most fully open cans, but is interesting to listen to thanks to the semi-open design. The HD-800 outshines everything else completely in this regard, but the D7000 is actually my second favorite in soundstage -- and that's just down to the fact that it's so much different than anything else. The fact that they kind of isolate is an added bonus. Despite all of this, the Denon's can't possibly hope to beat the above two cans working with good quality material, and that puts it squarely in third place. The worst thing about the D7000 is the fear you get whenever you pick them that they will fall apart in your hands (had someone else's D2000 fall apart on me during a meet, not a pleasant sensation)
Basically a subset of the HD-800. Good, but everything the K-702 does the HD-800 does better. Despite that, this is probably the best headphone in the world for competitive gaming thanks to it's imaging. Imagine a straight line through your head from ear to ear, extended just as far as the HD-800, but with very little in the front. Makes for an unnatural musical presentation, and despite it's width I'd actually rank the K-702's as second last for soundstage. For gaming it just works, and that's what I use the K-702 for.
Easy to listen to, non-fatiguing, and the shape makes it very easy to wear while lying in bed. That being said, if I'm not lying in bed I'm probably going to listen with something else. Soundstage is good, and despite the fact that treble is rolled off there is still sparkle and very little sibilance. The high frequency presentation means you aren't engulfed by detail at every moment but you appreciate it more when you find it, if that makes sense. The real bummer for me is the bass -- a little bit too muddy, a little bit too "one-tone," and that's what keeps me from really falling for these cans.
6.) HF-1 (headphile mods, woodied, C-pads)
Colored and unnatural for sure (big bumps in mid-bass and mid-treble to my ears), but on some music it just works. Worse than the HD-650 and K-702 in practically every techincal way, but a much better foil against the top three and thus gets more head time. These are my "The Police" headphones. Is it a bad sign when you have headphones for individual bands?
Easily the worst of the bunch. Sometimes you just need isolation though, especially when you're a musician, and these isolate exceptionally well. When I'm jamming on my TD-20, I use these. They aren't bad, but are clearly outclassed by everything else. I wouldn't call them "fart cannons", but things are leaning in that direction. Bass is big and somewhat muddy, highs represented well enough but feel spartan -- there is never any sparkle to them. Mid range is decent, but not creamy or lush, and the bass is intruding and polluting the region. Soundstage is nothing at all to write home about. A dependable workhorse, but nothing I'd use if I wanted to enjoy listening to music.
