The dedicated communication dongle between the PC and the headset sounds like a real game changer.

Right now getting fast enough and reliable wireless connection means either tweaking to death one's setup or spending car money on the entire setup. In particular normal people usually don't realize how crappy their wi-fi and assume it's all the same, which would end in blaming the poor perf on the headset.

Reminds me of Apple's AWDL, a similar workaround for crappy networks when the devices need a high speed low latency network. I do wonder if the headset here will do similar channel hoping tricks to join both the dongle's network and the normal wifi network.
