For years, manufacturers have expected hunters to take a “one-device-fits-all” approach to hearing protection and enhancement. As hunters ourselves, we know that doesn’t work. The sounds we need to hear on the range or in a duck blind are completely different from those in the turkey woods or deer stand. No two hunts are alike, and your hearing protection shouldn’t be, either. Whether your passion is calling in mallards, flushing upland birds, smashing clay targets, running and gunning a big ‘ol tom, or waiting patiently for a trophy buck, TETRA is dedicated to protecting your hearing, while helping you “Hear The Hunt.” 

At TETRA, we used our patent-pending Specialized Target Optimization™ (STO) to isolate and enhance the exact frequencies hunters need to hear for a variety of pursuits: deer, elk, turkey, waterfowl, range, and upland. We took those frequencies and created custom programs to enhance the sounds you most need/want to hear - like duck calls, gobbles, and voices - and protect you from those you don’t. Now, with our multi-pursuit device, you can get all the custom programming in one convenient device, and changing between programs is as easy as one simple tap.

TETRA isn’t just hearing protection, it’s hearing perfection.

Our Technology

Specialized Target Optimization

Our hearing devices feature patent-pending Specialized Target Optimization™ (STO). STO is the world’s first hearing technology that isolates and enhances the exact frequencies needed to improve hearing for your specific hunting environment. With STO, voices are clear, calling sounds natural, and the sounds of the game you are pursuing are all easily audible.

Tetra AlphaShield Multi-Pursuit

6 Pursuit-based programs in one device

  • Waterfowl Boost
  • Turkey Boost
  • Upland Boost
  • Deer Boost
  • Elk Boost
  • Clearcomm

TETRA products instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer full protection at the very moment it’s needed. For more sustained loud inputs, like loud calling, AlphaShield Compression™ limits the overall output to a safe level, then returns to normal amplification once the loud input has stopped. Never miss a sound you want to hear, and protect your hearing for life.

ClearComm™  is our proprietary algorithm that accentuates human speech while minimizing noises and distractions that occur outside of the frequency range of human voices. ClearComm is useful for better understanding speech and whispers of hunting partners, hearing speech on the range, as well as in other daily activities that require better hearing.

Hearing and the Brain

Research at Johns Hopkins University suggests that more hearing loss increases the risk of dementia. In one study, people with hearing loss were 24% more likely to have Alzheimer’s.* 

With hearing loss, our brains have to work much harder to make sense of what is being said, and even harder to filter out speech from unwanted background noise. Simply trying to understand conversations requires more mental energy and concentration. 

If basic conversations take up most of our mental energy, there is less opportunity for our brains to sort out and store other information. 

At TETRA, our goal is to minimize hearing loss for hunters and shooters, because research shows if we reduce hearing loss, we can also reduce the chance of getting dementia and Alzheimer’s.

Exchanged single pursuit no protection to multi- pursuit hearing protection and exceeded my expectations.

First Day

Received them today and tried them out squirrel hunting. I didn’t fire a shot, but I used the upland program. I watched a deer cross a creek about 80 yards away and could clearly hear the footsteps in the water. That was pretty cool. It also muffled the sound of shutting the truck doors. Fit was good but I wish they came with a lanyard just for peace of mind. Excited to use them goose hunting in a month

I have hearing loss, tried several different brands, this was my last hope. Received in the mail, was not programed correctly, had to send it back for reprogramming, running out of the 30 days money back. It seems that they delay the reprogramming and return to run out of time. I've had this problem with other companies. Disappointed because I really thought that the multi pursuit was a good product, considering the awards and reviews. I would like and appreciate some one to reach out to me, please.

Multi-Pursuit AlphaShield

The product seems to work very well, but I think I erred in using a cheap set of earplugs (should have used my Bose earphones) for the hearing evaluation to set its volume, as the unit amplifies sounds higher than I need; can the sound level be adjusted by me or do they have to be sent back in for proper calibration?

Customer Service Outage

The product is very good but customer service leaves a lot to be desired. Prior to actually purchasing the product I received numerous responses and phone calls about the product. Since purchasing I have left four messages and emailed questions with no response!
