Update to the review is up - now including movie & game performance.

I wish I had them, I would love to do a comparison. Unfortunately I don't own anything that would make for a good A/B test. I mean, it's kind of pointless to put these up against HD800's or JH-16's. I'll definitely post my opinions when they arrive though
The problem is that even those objective things are still derived from a subjective perspective. Yes you can say that "headphone X is thinner than headphone Y", but then you can also say that "headphone X gives an accurate representation while headphone Y really colors the music". You're still perceiving and describing the same thing, but they've got two entirely different meanings. Most of the time you can decode everyone's combined opinions into what you'd actually hear with some sort of reasonable accuracy, but for these I just couldn't. Hell, even subjective opinions can be pretty objective around here. For example, "X is better than Y" can easily be considered objective if you're comparing UE8's to those free clip-ons airlines give you
.
Have you tried them out with movies or video games at all by the way?
Oh I agree - everything is relative. But I think my point was that certain qualities are measurable. When you say "X is better than Y', a lot of what defines "better" depends on your taste and preferences. Yes, UE8 trashes free clip-ons on airplanes in terms of sound quality - but I am sure plenty of non-audiophiles would be happy with the free clip-ons rather than go out to buy an UE8 - because to a lot of non-audiophile people, cheaper is better (in this case, FREE!)
However, when you say "X is warmer than Y', "X is sparklier than Y', or "X is thinner than Y", most of the time these things can be measured via instruments. You can tell if the mids are recessed just by looking at the frequency response graph, for example. Of course, this doesn't automatically translate into statements like "Is this headphone balanced" or "natural" - once again that treads into subjective territory.

Great review.
I saw you leading to this in other threads and am happy to see such a nice comparison. So in terms of sound quality alone, you prefer K550. Is this by a large margin? Do you have any impressions of how these headphones compare to SRH840 or D2000?
Hmm, technically I don't "prefer" the K550 in terms of sound quality - if the A900X were just a tad less bassy, I would prefer the A900X easily. It is just the much fuller, more engaging of the two for music listening. But like I said, it's on the bassy side and that is an issue for me on some recordings where I want to hear the vocal or instruments more, but can't because the bass keeps distracting me. Classical instruments like cello which has a good amount of bass & lower-mids tend to have its lower-mids drowned out due to an overabundance of bass, which is very unfortunate.
The K550 may be on the thin side, but it allows me to hear all the details while still maintaining a very laid back presentation. On genres that are
meant to be bassy, though, the A900X is the more ideal choice - K550 doesn't produce the kind of impact intended for trance and techno, for example. The K550 is also not ideal for fast-paced genres due to how relaxed the overall soundscape is (I agree with Headfonia's assessment in this regard)
So, it really is like comparing apples and oranges.
They are just such different cans! So do I prefer the K550 overall by a
large margin? No. Not at all. It's just more pleasant for long listening sessions.
As for comparison with the Shure or the Denon, I don't have experience with them so I can't say.
MalVeauX did say this in another thread (A900X vs Shure940):
"Having both I am confident that the a900x is the way to go. It does vocals just as well, has all the same great characteristics but has the one thing the shr940 lacks... Bass. The a900x is the shr940 with bass capability so it's just the better headphone. I feel the -900x completely replaces the shr940 in every way."
Not sure how similar the 940 and 840 are, I am sure you can get others to help you with that comparison though.

Good Review Bagheera!
Question is... will you stay with both headphones?
Haha, having now tested movies & game performance, I think I will. I like how music sounds on the AKG - it's different from the AT, but still pleasant and sufficiently engaging (my wife really didn't care for the AKG though - she did not feel engaged to the music at all on them. She loves the A900X a lot, though she agreed it's on the bassy side)

I honestly feel that the A900Xs are better for positioning sounds in an horizontal plane, and the K550s are a bit better regarding sounds from above and below. But I'm just assuming, I really need an unbiased comparison in that aspect, because it'll be the main deciding factor in which one I'll buy.
There's no such thing as "positioning from above and below" in headphones. You get two audio channels feeding two drivers, that's it. Any "vertical positioning" would have to be achieved via binaural recording or simulated binaural effects (such as Dolby Headphones). Some games that have good sound engines will simulate vertical positioning via virtual binaural output (the old Aureal 3D standard comes to mind... long dead now. Pretty sure EAX 3.0 to 5.0 supports this as well, but that is also falling out of use in modern games), most I don't think bothers with this feature.
In any case I am very certain the A900X has better sound positioning than the K550, period. If you feed binaural recording to both, the positioning will still be better on the A900X (including the "above and below" effect you spoke of).

I own the AD700 for positional accuracy on games, and was thinking on the 900x as my next gaming can. How much the upper bass peak affects positional accuracy?
I don't own any of the AD-series, so I can't really compare. The A900X positions
very well though - it has to do with how
focused the sounds are on the A900X, as opposed to the K550 which sounds kinda like things are just "floating out there".
I personally didn't find the bass boost intrusive for games and movies (sound positioning or enjoyment); I actually think it enhances them. But if you are coming from open cans like the AD-series, it may be on the bassy side for you.
