I remember seeing it, but then I forgot about it since I concluded that I don’t like how starkey HAs work or something. Forgot what turned me away 
And there’s no topics about it so I’m not sure how many people know about itm
This video reminded me of that mic
From video and specs as I remember, it looks like providing same stuff as roger select.
Different is that starkey TM is working only for their HAs (maybe even only for newest, didn’t check that).
And price is, in comparison to select, a bargain.
Especially if you’d like to use select on starkey HAs.
Also, I don’t know if you can create a network of them (altough, selects in network aren’t IMO that cool, since they’re not network of table mics but network of mics hanged on someone)
But, yesterday I said that I’m surprised that no one else went through the ordeal of inventing better mics, since I forgot this one.
So, here’s a bit of publicity for it. I think it’s definitely worth looking into it.
