I have one thats about the size of a back of cigs. The microphone is covered with foam so I don't get alot of wind noise. I made an elastic "pocket" for it on my boonie, run the head phone wire down the back and only use one of the two ear pieces. Wow I can hear the wing beats of the waterfowl as they fly over my archery stand BUT with both ear pieces in my ears I can't tell what direction the deer/squirrel is coming from. The problem is somewhat better with just one ear piece. It seemed that sometimes Scotty just beams those deer in front of me, never heard them coming. Not now

I may not know exactly where they are coming from but I do HEAR em.
