Just got the Nuarl NT01AX....OMG, my mind is blown away by them at the moment. They look absolutely stunning and sound. They remind me of my of my ER4XR, it's hard to believe that they are wireless...tons of details, a realistic soundstage, and a bass slightly above pure neutral. Listening to live albums now to test them properly, and you can hear the reverb in the halls they are playing. Excellent separation between the singers and the instruments. Everything sounds beautiful and realistic.
That said, the box they came in can go to hell. They were fixed to thin cardboard, and I accidentally ripped them out, and I am being paranoid about damaging the nozzle cosmetically. I shouldn't worry about that, since it is not much worse than pulling off a tight eartip, is it?! The carrying box is also meh. It has a small button that opens a latch and feels kind of cheap. The button is super hard to push with long-ish nails too. that being said it is small. If you have any questions ask me. I will probably get a better review up after playing with for a while.
Edit: Can't stop listening...Nuarl motto is natural and neutral, HDSS is a certification that the sound has as little coloring as possible. That is my preffered sound sig, so keep that in mind, but based on first few hours I like the sound of these even more than the MW07s I demo-ed a few weeks ago...amazing high mids and highs, great bass when called for (Killshot bass drop sounded amazing), and very nice detailed mids. The interface is clunky so far (not used to it), but I love the sound coming out of this tiny driver!
