harold knight blowing a call with hearing amplification from TETRA Harold Knight blowing a duck call with hearing protection from TETRA

“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."
