I guess this the place to share experiences with the DT-1990. I've had these for over a month now, I'm running them from a modest FiiO X3 II + Fiio K5 combo. They sound really good, accurate, nice bass. I'm constantly switching back and forth with my DT-770 to see if 4 times the price is 4 times the sound. Aaaannnd, the DT-770 are no slouch, the DT-1990 wins on the clarity, they sound more natural compared to the DT-770, the DT-770 sounds...I don't know "metallic," really distinct differences on the the treble. The bass, on the DT-1990 extends really nice, with some sub bass; however, compared with the DT-770 the later has a really nice rumble, a subtle growl that it's really nice, the DT-1990 does not have that growl, but its bass is really good, articulate is the word they drop all the time when it comes to the DT-1990 and I'll just borrow that word. All these impressions come from using the balanced pads. I tried the analytical ones, and they're not my cup of coffee, I like some more bass on my cans.
Regarding that quest for clarity with great lows, I went ahead and bought three pair of pads:
- Dekoni Elite Fenestrated Sheepskin.
- Dekoni Elite Velour
- Brainwavz Velour pads.
So far only the Dekoni pads have arrived, so I'll share my experiences with them:
Fenestrated Sheepskin: The quality is nice, I would expect better stitching given what they cost, but it will do. Sound wise, these are weird, they do something odd to the sound signature. They give a wider sound stage, really noticeable, no golden ears needed to hear it. And really flatten out the headphone, everything is taken to almost the same level, lows, mids and highs, with a tiny emphasis on the mids, they do a nice job of taming some screeching highs on some songs. But it's really cool, the best way I can describe them is: they are a better pair of analytical pads. However the bass is also flattened out, but really nice quality, buttery smooth, punchy, fast. If people enjoy a flat signature you could try them out; and if you have some money to spare.
Elite velour: from the get go, this is not velour, or at least not the same as the stock pads velour or the velour on my Hybrid Brainwavz pads. I can't describe it quite well, it has ridges all over. I'll post some pictures if anyone grows interested enough, or check them out at Amazon. Getting over that...surprise, I find the build quality better than the one on the Fenestrated sheepskin. Now, these pads give that extra bass I wanted, not jaw braking but it's very noticeable over the stock balanced pads, it doesn't quite give me that "DT-770 rumble" but it certainly takes the bass up a few notches. The clarity does not suffer...much, it lowers the highs a bit, at first I thought it muffled them, I gently turned the volume up a bit and the highs are felt to what I was hearing on the stock balanced pads, with the added bass that I was looking for. I don't know if that's a good thing, having to listen to a higher volume with these pads, switching back and forth with the balanced pads, I'm not getting that extra bass with the stock balanced pads at higher volume, so I achieved what I wanted.
TLDR: Elite velour pads, "better" stock balanced pads, although I'm having to listen at a slightly higher volume.
I'll use the Elite Velour pads for a couple of days, then switch over to the stock balanced pads and the Fenestrated Sheepskin and feel how that goes.
Confort wise, over the stock pads, both of the Dekoni pads are softer, that's a given. The hole on the Dekoni pads is narrower compared with the stock pads, luckily I have small ears so that doesn't bother me. One other reason I felt compelled to change the stock pads, is that one the balanced pads had flattened out just after a month of use and my ear was touching the inside of the headphone, I find that...odd, but I'm not about to claim the warranty over that.
One last, irrelevant thing: It's been years since the last time I used a material other than velour on the earpads, so when I put on the sheepskin ear pads, they were cold. Silly thing I know, but that caught me off guard, they quickly warm up and become tacky against my skin, but I only notice it when I moved them. No, I don't hear any sound change after the sheepskin warms up.
