These appear to be the TE-05 drivers in plastic housings? Feel free to correct me on that. MMCX connectors same as the TE-05/07.
Very pretty. The blue/teal-coloured ones look might nice in particular.

Saw some press releases that suggests they should be in the NA market soon.
The TE-05s I found pretty underwhelming. Perhaps the plastic housing will change things for the better (probably not). I'm mostly interested for the looks. If the price was a bit lower, they might have been fun as something to beat into submission with EQ.
