This just arrived at my office:
First general impression - everything from the pack to the earphones shows quality.
Good selection of silicon and foam ear tips, changeable filters carry box that feels that it could survive tank driving over it.
The key reason to buy them (except for high expectations towards the sound), was a slightly more compact shape size.
I have Fiio H5 and had few similar shape models before, and all of them create a pressure point in one of my ears. I can already feel it will not be a problem here.
Too early to say anything about the sound (and I'm not audiophile enough to really review them) but initial impression is definitely positive.
Their jack design is a bit thicker than my phone but it should not be a problem when I ger Hiby R3 (and probably change to balanced cable anyway).
