I' ve used the Walker Game Ear during bow season and have found it does enhance my ability to hear. It does give an ' windy' background sound though. Like putting your ear to a sea shell. That didnt bother me though, because it actually drowned out the ringing I have in my ear.

The problem for me though, is after I would take it out, my ear would ache for couple of days. Hence, I dont use it much anymore. This is just something that probably just affects me, but I thought I should mention it.

Its a shame too because it did help with my hearing and they arent cheap!
