Not nearly as knowledgeable as @M0N, nor will I pretend to beā¦ Probably havenāt had nearly the time to listen to them either.
I apologize for the novel.
So, just as a rundown of my set up, I am using the DAC in my ZEN, RCA split (line out, not variable so āPower Matchā and āTrue Bassā wont effect the other amps) to the BasX A-100(I have removed the jumper mod for this) and xDuoo XD-05 (OG). Iām running through with my DT-990 Pro, K550 MKIII, Dekoni Blue (Swapped back to the stock hybrid pads), and the 5XX. I donāt have my 4XX on hand, so Iām gonna have to wait to compare.
Power: These are NOT the easiest thing to drive. Granted, the T50RP (Blues) are notorious for being power hungry, but the 5XX seems to want ever so slightly less then the 990 Pro. 2-3 oāclock on the Zen, and Noon on the XD-05, both on high gain with their bass boost. Hardest to drive? Not at all. But they do want some juice to get going.
Comfort: These feel a bit like the 990 Pro after the Beyerdynamic has been broken inā¦ With some cavoites. Of course, there is the larger pads, meaning less likely to touch your ears, or your ears the driverā¦ but the fabric they chose is a bit rough, as it isnāt velour. I can say that even with the deerskin comfort strap on the Dekoniās, with the stock pads, they are the least comfortable long term to me, given the much higher clamp force, with the AKG being the most comfortable.
Build: They really do feel kinda cheapā¦ by far the 550 and Blues have a better build. They have about the same movement as a 990 (with the way the cups angle forward and back). While the 990 is louder, the 5XX has a sound that reminds me of noisy shoes, if that makes sense to anyone. As a quick note, the headband on my unit smells fine. I can also say I disapprove of how difficult it is to remove the pads, and even more so that the pads are glued on. A pad swap could potentially help, if there are any that would fit.
The left and right indicators are in glossy lettering on the back of the plastic piece connecting the sliders to the headband, contrasting against the satin finish. Beyond that, the connectors are angled slightly to the front.

Bass: These are lacking a lot of sub bass, and some kinda bass boost can help, but wonāt get the job done. Otherwise, I can definately agree with M0N on his statement that itās round. Nice, full, clean. Just lacking that sub punch. Sadly, that kinda kills it on songs like Dare where itās supposed to be there.
Vocals: This really made me want to turn away from the BasX (which I typically prefer) in favor for the ZEN or XD-05(A bit more the former then the latter). They didnāt sound quite as natural on the A-100 as they do on the others. While it seems to have a slight favor to female vocals, itās fairly natural, though will bring out some of the characteristics of the mic being used. In āSomethinā Stupidā I could clearly hear more of Nancy more consistently. I can say that in āGlassy Skyā, I could tell more of the sibilance in the way she hits an āsā. Nothing unpleasant, but it does stand out a bit more.
Pianos are absolutely BEAUTIFUL. The K550 come up next in performing with piano, but particularly with RE:0, none of the others made me feel like I was listening to the instrument crying.
Drums. Nice. Quick. Snapy. Not sure what more to say. They sound good. Sadly, in some more aggressive metal, they become the star of the show.
Initially, I thought these sounded really flat with metal, and it was just bringing out the drums, but with time it has gotten better.
Sound leak: Even between the two open backsā¦ These leak ALOT more. Granted, Iām still the kinda ass who would absolutely take these out in public, and I have, but to each their own.
Space: This is aā¦ Strange point for me. On some songs I feel itās a bit exaderated, while on others, I feel like itās not quite as much as Iād like it to be. For example, āĪsŹį“sā and āĪsŹį“s ļ½RETURNS ~ā donāt sound quite as great and spacious, but I also donāt feel like the music is trying to reach for more like the others.
Overall, I like them. From what I remember (it has been over 6 months), I donāt like them as much as I liked my 4XX, but Iāll have to get them back in had to really compare the two. Yeah, theyāve got their problems, but so do most other things in the price range. I feel the pads could be better (they donāt exactly seal well around my ears, and I can feel it, though not as bad as the beyer pads).
Again, I appologize for the lengthy, and probably not too great descriptionā¦ And taking so long on this.
**Edit: I will admit I kneecapped the Blues, as those are not the best pads. Iāve personally been using the Dekoni Platinum Pleather pads, but I wanted to try giving a more āout of the boxā approach.
