If these ever drop again, maybe this review will help those interested. To my ears, they go head-to-head with the TFZ Exclusive King and Blue Ever Blue 1200EX, two of my favorite ~100 USD earphones.

Sorry if you feel I misled you. I just write what I hear and still stick by my complete thoughts on the low end:
"Bass on the D6 is elevated slightly over neutral with great texturing and decent extension. The balance between mid- and sub-bass is quite even, with neither taking on a larger presence. The D6’s bass doesn’t have a ton of slam or authority to it, going more for a detailed presentation than visceral. Not really my preference, but it works in conjunction with the way the mid-range and treble are presented. They’re certainly not a bassy earphone, but they’re got more umph down low than your typical BA only product, and some other single dynamic models like the Whizzer A15 Pro Haydn."
If you were expecting an EDM king based on that, not sure what to say, lol.

TheContraptionistHey, thanks for replying! Especially given how long ago you wrote that to begin with! No, if you truly hear that, then I don't fault you. I certainly wasn't expecting, nor would have been interested in, something with a huge level of bass. But the "elevated slightly over neutral" part led me to expect that I would be able to at least acknowledge it's presence, and be able to hear an upright bass or even the bass guitar in tracks with energetic basslines. Unfortunately, the bass is only close to neutral on tracks that don't have anything in the bass spectrum =p
I feel like I'm pretty sensitive to bass, and anything that's actually more than neutral gives me headaches, so these seemed like a safe bet. No headaches from the bass at least! I have a friend who only listens to instrumental who loved them when he tried them, so passed them on to him, so no harm done ultimately.

If anybody is expecting a balanced, neutral, or anything other than "obscenely bright" signature from these, please save yourself the trouble.
These are the brightest headphones I've ever heard. The pains I had to go through to even *hear* a bass response are obscene.
Maybe a (much) earlier run was better balanced. Crinnacle originally described it as a V-shaped signature on his list (it's not, and he's since updated it to bright...). I bought my pair two years ago, so it must have been a very early run indeed, if that's the case.
So just warning you off, because there are several surprisingly false claims in the reviews section here: If anybody claims these have rich, warm bass, or a good sub-bass extension, they're outright lying, which is a crappy thing to do. They'd be great if you just listen to classical, but even lower register woodwinds don't render well with them. Build quality is fantastic, the cable is great, and if you like a cold, clinical, bright sound, they'll be fantastic.

FulluphighI’ll have to wait to see if I agree. The pair I received were obvious returns and missing most of the parts. They are now on their way back to A&D for a new replacement.

I got my D6 earphones today. Right out of the gate they sounded pretty good. A bit bright but I'm letting them break in by playing a 'low dynamic' playlist on Tidal at low volume. Came back a few hours later and now they sound positively tinny... unplugged them and plugged in a pair of Sennheiser PX 100 - II and directly compared on a few songs. No comparison, the Senns are (so far) much better with a rich full sound. So... I'm really hoping that the D6s will improve.
Update: They sound much better after about 36 hours of breaking in with a much fuller sound. Inner details are lacking a bit, so I'm hoping they continue to improve. I'll give them another day or two and then do another comparison to the Sennheisers for a final evaluation.
Update II: Happily, all the prior negatives are gone ;-) These phones do have a breakin period and at 56 hours all doubt has been removed. They may even continue to improve but at this point they're entirely satisfying. Clean, neutral sound. A great budget set of earphones for those who like clear, transparent reproduction.
I did directly compare them again to the Sennheisers and now the Sennheisers boost in the midbass is obvious. That bass emphasis is very attractive even for someone who's not a basshead. The problem is that the Senn's bass emphasis masks the other frequencies and for instance on Paul Simon's "You can call me Al" especially @ the bass solo @ 3:44 the Senns make it sound a bit distant and slightly muffled. Whereas the D6s render it much more clearly. Thumbs up for me.

Just some thoughts on these IEMs after using them for a few hours. I like them. When I first put these in, I thought they sounded distant and shallow. After a few minutes, I realized that the sound is really clear and well defined, and not muffled or muddled. There don’t seem to be any gimmicks in the sound reproduction. Nothing seems artificially high or low. Highs, mediums and lows are distinct and really clear. I’m not saying that it’s some type of neutral reference sound image, but it’s really crisp and balanced. I can hear things in vocals and instrumentals that I typically don’t catch with earbuds. There isn’t a lot of bass, but what there is pops. If you’re looking for heavy bass, you won’t find it here.
The soundstage is good. There is good separation between left and right, especially on remastered tracks that I tested. It’s fairly open. They are a solid headphone, and a bit heavy. But they stay seated in the ear. I had a little fatigue after a couple of hours, but not too bad. The wire is a little funky, and I don’t know that it needed to be braided. The pouch is made of leather, and is one of the nicer cases I’ve seen for earbuds. So is the cord wrap, which I’m not sure is needed but is a nice touch.
I’m using the one set of foam tips that came with the earbuds, and they fit well. I can’t for the life of me figure out how to attach the earguides, and the A&D website is no help. But so far I don’t need them.
I don’t know that I’d use these in a gym, but I think you could. Overall, I’m pleased. I found myself wanting to listen to different tracks to hear how the headphones performed on all types of music. I think it’s a good sign when you keep telling yourself, “just one more”.
All in all, I find these to be excellent IEMs. If they come back for another drop I’ll probably get a second pair and some for my kids. I think they’re that good. Just my opinion, and your mileage may vary, as they say.

Has anyone found fit to be a problem? The housings are a touch big? And so noise isolation is difficult?

ConBrioHousing is definitely rather bulky. I don't have an issue with getting a good seal, but they get uncomfortable pretty quickly.

That's a D? I'm just gonna call them Hoss!
That being said, how are these compared to Tin T2s? I have the A&D D3 and was completely underwhelmed by them.
Can't argue with that build quality and warranty, tho...

Do the crescents have a hyper-bright signature? I was under the impression they were more neutral. These aren't neutral by any means.

Fantastic treble/mid focused IEMs! They have amazing clarity and soundstage for the price. I have IEMs that cost multiple times the price of these gems that do not have the clarity and soundstage of the D6. If you favor classical or acoustic music these are the earphones to beat in the sub-$200 range.

Relatively new to audiophile headphones, so I have this question. Will these be fully functional if used on a smartphone, specifically the Huawei Honor 7X? I've heard some of them need powerful amplifiers to work?

AkeebGT86The impedance is at 16 ohms and the sensitivity is 105db, so these should get pretty loud on your average phone. Most IEMs don't need much power to be driven because they usually have a low impedance and a high sensitivity.
