I have had them. They are a pain for a person that sweats a lot like me. Kelp them in the shop(not cheap to fix) half the time. The bad thing is when in a crowd of people you can not make out who is talking. They may be better now a days. They were very expensive(bell tone) back in the day when I bought mine back in the 80's. I just ask what did you say till I am able to hear them or read their lips now days. Good luck with yours.
