A ton of treble, "fixed" with new pads, and comfier, too, afterward
I'm not really good at picking apart the fine details of sound, but darn these things have high treble.
After swapping the stock pads with some brainwavz oval hybrids I had kicking around, it brought it to a listenable level. And I mean that in earnest, I couldn't even use these things to listen to music before padswapping! Not trying to hate on the treble heavy sound signature, it just genuinely hurt my ears. Maybe I'm sensitive, I don't know, but that's my experience at the very least.
But hey, these pads bring it to a more neutral sound, even if it sound like it's muffling by just a tiny bit. More comfortable with different pads, too, regardless. Headband is nice and soft, clamping isn't bad at all (my head's pretty large, I've been told.)
The comfort rating with stock pads? I'd say 3/5.
But with the brainwavz oval hybrid pads, it's bumped up to a 4.5/5, really. Genuinely.
Sound quality is pretty good anyways, would recommend some kind of amplifier/power source to drive 'em, etc etc. I don't really have much more to say in that regard.
Build quality? I mean, I pretty much just got these, but they feel solid. Like, REALLY solid! Sort of rubbery texture on the outside grates, which I like. A lot of what I think is metal around on everything, too. Headband's quality is also on point as mentioned above. My only concern in this field is the adjusters. They don't really feel all too clicky/smooth, more... grindy, like there's not much of a groove for the adjuster to go into. Or something. Oh, it wobbles a bit too. Which is nice for earpad positioning, but feels kind of weak when I'm forcing the cups to go up or down with my hands.
Comparatively to my DT880 32 OHMs edition, the actual cord has a bit of rubberized texture to it, too, on the 990s in this review. The 880s have a slick, plastic feel to the cord, unlike these.
Don't think I have much else to say about these cans. Was a bit expensive, but they're pretty decent anyways. I like 'em, I like the look and feel of 'em. If you wanna put another $30/$60/whatever into them for actual listenable sound (again, just my opinion,) I'd say yeah. But if you're looking for a better initial product, I'd try the 880s.
Their sound signature is a lot more friendly than this one. And, hey, there's always parametric EQ!
Would recommend to a friend.
