Why not touch bluetooth? Any cons?
Yes, they are complete and utter sh!te !
I fly to one airport that uses these and I can barely understand a word the pushback crew is saying. Totally garbled and distorted I always have to ask two or three times certain questions. I was so concerned I filed a safety report fearing misunderstandings would lead to an incident. Model in question was a bluetooth from Peltor I believe. Junk!
