I have had a Walker game ear for over 12 yrs. I don't hunt w/out it. It was, I believe. one of the simple, original models. I shoot right handed, therefore I wear it in my left ear.
It breaks up the noise from the muzzle blast, yet helps in my hearing. As far as wind goes, it has to be pretty heavy to be a bother.
It fits nicely in my ear. Today they make all sorts of higher priced ($450) models.
