Headset
Just thinking out loud…
Everyone has a cell phone. New AirPods (and likely others) have great noise cancellation, some even carry certification as hearing aids. In decent shape, the battery life is good enough for a whole match and more. And you can use only one at a time, while the other one charges in the case. 3-way calling is also a thing. And with an internet connection, I’m sure there are apps for decent conferencing and such.
So…why not use it as a ref headset?
