I have some Chris. They are absolutely fantastic, I panic if I lose one of them, as I did in France... I refused to leave the camp site until I had found it. I got them through an audiologist. Many on here will know that I'm partly deaf. If I didn't wear earplugs on the bike, my ears would ring for days afterwards, and I wear them to protect the hearing that I have left. They are so good that I forget that I have them in. Not cheap, mind. I'm sure they'd do them with a handsfree gizmo.
