I was one of the guys Len hunted with this week. I have had other friends use hearing protection in the past while hunting on coyote stands or even while hunting big game. It usually causes a lot of issues. Most units really hamper one's ability to hear. I have become very frustrated, at times, while trying to communicate with partners wearing different forms of hearing protection. This is the first time there were zero issues with being able to communicate. The Sound Gear units impressed me quite a bit from the non-wearer's point of view. Anytime I had to whisper while on the stand Len did not have any trouble hearing me. The units were so small that most of the time I didn't even notice Len was wearing them. As I get older my hearing seems more and more important to me. I'm thinking I might just have to get a set of these Sound Gear hearing protection units for myself. On a side note, when Len comes out to hunt he usually has all kinds of different gear to test and use. This trip was no exception. On this hunt, aside from his wonderful 6.5-284 (which was an absolute joy to shoot), the Sound Gear product was the highlight, for me anyway. It's a cool little tiny product that makes a difference in a HUGE way!
