Bluetooth headbands

Has anybody tried one of the Bluetooth headbands yet? My wife bought one for listening to sleep aids in bed and I think it would work under a half helmet. In fact I tried hers on and it fits under my half helmet but it is way to cold to go for a ride today 10F +/- today.
Here is a link to the kind of product I am talking about.

I have a similar item, it is a beanie. It works for casual, background type listening. Not high quality, and doesn't get very loud. Just me, but I couldn't wear that fleece type headband in warm weather. Only you could judge if that would be loud enough over wind noise to be enjoyable.
