They makes good dynamic drivers, though. They makes good innovation, however, sometimes may screw-up with realization, for example, w500 ahmorph was one of the tunable IEM ever produced, that has 270 degree rotatably dial that change its sound signature for any type of tuning. But you have to set both left and right earphone dial to the exact position which is not easy to do, otherwise, you will end up with channel disbalance that effect negatively to the SQ.
They sound signature may vary from model to model, but they signature type of tuning is musical reference, slightly W-shaped sound that close to neutral, with good bass and slightly darker safe treble. They try to make a good balance for timbre between “analog” and “hi-fi”. They mostly oriented to musician and for audiphiles that likes music like Rock, Metal.
I highly doubt that AAW will be a good fit for U12t fans.

They have some really good looking iem. Really liked the colour of Pola. I know it doesnt matter but thats the first thing i noticed. I had to look them up, since your post made me curious. I love it when someone dares to do something different, and they did that with the iem you mentioned.
On paper that ash looks good. DD + 6 BA, and 4way crossover. Isnt heavily overpriced either. So is it their sound signature, or their marketing stopping them of being a bigger name in iem world? because they dont get mention here, nor on youtube?
