Curious what people are using for hearing protection when in the blind ? I don't want to wear foam plugs or muffs. The muffs would be uncomfortable with sunglasses and if I had to wear them over a beanie and I don't want to hassle with taking them on/off when birds are coming. I have been using the SureFire in-ear units from Cabelas but I cannot hear the birds working(wings/quacks) nor can I hear other hunters very well. So, I am looking for suggestions on an in-ear amplified unit that isn't too expensive. Walkers Silencers look good but I have read many mixed reviews. Thoughts ?
