This seems promising if the physical button on the muff can activate a walkie-talkie phone app like Zello. A phone is required for it to work at all, but I think Zello can work over bluetooth between phones without a cell signal. Zello has a lot of info on their site about compatibility with third party headset hardware and would probably test it.
Anyway, key points of concern:
-dont think that mic swivels
-one sided audio in muffs
-requires the 3m Peltor muffs
-95F is Max storage temperature, but operates fine at higher temps (?)
-cant tell if battery and ear cushion are replaceable (emailed 3M about these two points and using with an app)
-unsure about noise cancelling, overall quality. I think YouTube reviews (non arborist application) weren't quite glowing. Wouldn't be surprised if you can't be heard while running a saw wide open or standing behind a chipper.
For what is worth I'm not a huge fan of the pads on my 3M Peltor muffs, I prefer to have plugs under them if I'm around the chipper or am running a med or lg saw. I think clamping them on the helmet in storage wears the foam out, which is replaceable.
