Just a small first impression from my brief demo today at KLIAV Malaysia, only comparison I have in similar price point is the TFZ Exclusive 5:
Tuning seems to be quite balanced, with a more prominent upper mid compared to Ex5, with much less bass quantity (might be due to tips not sealing). Very comfortable and compact housing, slight less than average isolation, inline controls all working with my Xperia ZR, and quite a lovely matte surface design. Can't feel whether it's plastic or metal for the short time I have it though. Overall it's quite on par with the $99 price point, though I haven't tried the other acclaimed sub-$100 budget kings like the Magaosi/ Audbos K3 Pro and the Kinera H3, so can't give much comparison except my Ex5...
