They suppress sound - Safariland - TCI Liberator Hearing Protection with Adaptive Over-the-Head Suspension

They work. They suppress the sound of gun fire. The battery compartment is water resistant. So they have that. I'm just not all that impressed with the rest. There are two significant things that I miss from my old ear pro. First is that you can't turn the volume up very high. The highest volume is like, normal volume. My old ear pro I could turn it up enough to be able to hear what was happening in the next room. On these I have them turned up all the way, and it's normal talking volume. I'd like it more if they could be a louder. I like having the option of turning the volume up so that I can have super-hearing at the range, so I can hear everything going on around me. When I'm wearing these I feel so limited on what I can hear going on around me. I'd almost say you hear less than what you hear without them. I tried all three settings and I couldn't make any improvement. They do block the sound of the gun shot, so they do what they are supposed to, but I'd give another star if I could turn the volume up. The second thing that I don't like is that they don't fold up. My old ear pro could fold up nice and compact, easy to store in my range bag. These don't, I can't put them in my range bag because they take up too much space. I carry them separate. A solid three star.
