Maybe Poly 2 will use USB-C and require an adapter to work with both mojos.Come on!
It was just a crude suggestion, saying it could have been done.
If you are really nitpicking , look closely, the ends of Toslink and coax inserts are tapered in, they could go into the bottom part of the new insets, no?
OK not 8mm, make it 10mm.
Old Mojo+Poly cases would not fit new Mojo2 anyways.
Little hex locking screws on the adaptor could fix it to Poly firmly - Poly-Mojo is not all that stable, the case or a sleeve takes care of that.
I‘m kidding of course. But that would have the same degree of elegance as Mojo 2 needing an adapter for Poly imho.
