Yep, Doppler and Apple delaying product.

A friend has worn the simple noise cancelling version of the Hear One to a loud concert. She loves them.

Another friend has the Bragi Dash earbuds and was complaining of some Bluetooth drop-out.

IMO, would rather have a neck band sending out RF than something sitting inside my head. Maybe the new passive WiFi solves that concern at 1/10,000 the power?

IIRC, the new passive Wifi requires a reflector device in the room.

I think that's the problem; they have a good idea and an approach and developing partnerships, but product delivery seems.
