This is the type of thing I expected from the ex-researcher. See, now he dug a hole for himself. I'm glad to know UM was aware and let the community test it.Early this year during CanJam NYC, UM actually presented a prototype of Mest MK3 with a switch to disable/enable its BCD driver. I spent some time in a quiet corner testing and was able to hear the difference.
Seems like the piezoelectric driver tech by UM is not traditional bone conduction from his vid, but still has contributions to sound that he can't understand. It might be bone conduction or another effect, but it's not a cash grab as he said.
Having said that, UM's marketing descriptions can be improved
