Surefire makes some that look like hearing aids and can be had for about 15 bucks. I have some and they are the best ear pro I have ever used, they stay in place and are very comfortable. If you would like to spend more you can purchase their electronic ones that are somewhere around 1000 bucks. That's a little out of my price range for ear pro.
