A:Answer I tested a pair recently with good results. I live in NH and called my gf on the phone. She was at our home and I was wearing the OpenComm, with no helmet, and riding at about 35 mph. I do have a windshield on my bike, which likely helps with wind noise, but it does not eliminate it. I had really good results, in that we were able to have a normal conversation.
I'm hoping we can both wear one for normal riding, so I don't have to turn my head to speak with her (she doesn't speak very loudly lol)
