I wanted to like these, but really I'm not impressed. Their ad was almost indecipherable. Poor audio on all the people speaking. Ranging from hollow sounding voices to tinny to muffled, to microphones set to very low gain.
The poor quality audio in this ad makes me question if they really know audio at all. Unless they're completely parting out the design, manufacturing, assembly, and testing of the product to an outsourcer. In that case, a good outsourcer could possibly still put out a decent product regardless of the advert.
I'm with you on the generally very poor audio quality of comments by the "person-on-the-street" earphone testers, but I also thought it quite odd that the voice-over narration in a couple of the videos is a computer generated voice!?
