So, I just received this set from Amazon about an hour ago. These were never on my radar, and it was an impulsive buy after noticing the reasonable asking price of $650. And while waiting for delivery, I sifted through 223 pages of this thread, and oh my the first impressions are all over the map. It was kind of extreme, but I guess it shows how different we hear things.
Starting with fit and finish, it's more aesthetically pleasing in person than what i'd expected from viewing pictures. Simple packaging with a nice carrying case. It feels lighter than 360g on my head and although the underside of the headband has plenty of padding, I wish it was a bit wider. I got the black ninja edition, and I'm liking the subdued and mature look. The earpads are on the smaller side though. They don't fully cover my ears, and the top and bottom of my ears are pushed down slightly. The upside is, they are still fairly comfortable.
Moving to the sound, my initial impression is that I find them overall a bit incoherent. I don't feel they are well balanced across the FR.
But first, I want to say this HP is very amp dependent. And I'm not just talking about power requirement. I was surprised how the overall sound/tonality changed quite a bit from amp to amp. On my Topping A/D 90 stack, it had lot more air and overall had a lighter weight to the sound. On my Focal Arche, it was much fuller and felt more balanced. The Schiit stack was a bit different too. I'm curious to see how it'll sound on the tubes. I'll test that once I receive my ZMF Pendant, hopefully next week. So I think this contributes to inconsistent first impressions on this forum.
I don't find the treble 'hot' or harsh, but on some occasion, I do feel its emphasized in an unnatural way, particularly with less than ideal recordings. I feel like Beyer wanted to put strong emphasis on clarity and air, they forcefully achieved this in an unnatural way. I don't consider these a bright set, but the tonality is on the lighter side and I find very little weight to the overall sound.
The mids are quite difficult to put it in words. I can't quite place it. Sometimes the vocals seem way recessed but other times, feels quite forward. Gonna have to put some more hours into it with tracks that i'm more familiar with.
The lows are nothing to right home about. I don't find the quantity lacking, but wish they were a bit tighter all around.
I'm also detecting a slight channel imbalance (left bias), but will need to test more to be sure.
Soundstage is what surprised me the most. I've read lots of comments comparing these to HD800s, but to me they sounded way boxed-in, even compared to the HD650s. It was way too intimate and felt more like a closed-back than its semi-open design.
On the other hand, Imaging and instrument separation is quite good.
Overall, I've heard better HPs in this price range, and although the amount I paid ($650) is fine for what it does, I just don't feel like it's a flagship quality.
It sounds like a good headphone from 10 years ago. Gotta say I'm a bit disappointed, but I'm not gonna give up yet. I'll put some more hours in and report back with any new findings.
And of course as always, YMMV.
EDIT: These are exceptionally good for gaming, particularly for competitive FPS. And I kinda bought it for that reason, so in that regard, I'm extremely happy. I just wish it was the same for music.
