“I can’t tell you how important it is to be able to hear when hunting. I’ve blown calls and fired guns for 50 years, but until recently didn’t realize how much I had damaged my hearing. TETRA not only helps me hear game again, but also protects me from further damage.”

Average Customer Rating: 5

"TETRA hearing devices are much better than any other product I have tried out there. The sound of the call is not nearly as muffled as my old custom ones. I take the old ones out to talk in the blind. I leave these in and carry on a conversation just fine."
