For years, manufacturers have expected hunters to take a “one-device-fits-all” approach to hearing protection. 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. Changing between programs is as easy as one simple tap. Our CustomShield devices and custom molded for the most personalized fit possible, and have a rechargeable option.

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 CustomShield 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.

I have used them 5 or 6 times now. Some half-days some full-days in the field. The fit is great. Hardly notice them at all really. The lanyard gets caught up (wader straps, hood, etc.) occasionally but has not pulled them from my ears. Adjusting the volume on a windy day requires a little patience and tweaking to get it right. I've worn a hat & facemask over them and it only takes a small adjustment on the volume to eliminate the initial squeal. I am amazed at what I was missing in the blind. I now hear birds before I see them a lot of times. My hunting buds have noticed that I'm not asking, "What?" as much anymore either. The noise cancelling is awesome. I watched my buds shoot and I barely heard the report. Same for when I shot. Haven't had to change batteries yet after about 50 hours of use. After using them for an entire day, it does take a few minutes to adjust to them not being in my ear. (I have some significant hearing loss.) The other day, I took them out after we pulled the boat out of the water and I felt as though I had just gone deaf! I had gotten used to hearing everything around me with them in. I am very satisfied with them and highly recommend to anyone who is even thinking about them. Customer Service is very good and responsive. It did take about 3 weeks to get them but it was over the holidays so no sweat really. They are worth the wait.

Nebraska Hunt

I really enjoyed my Nebraska hunt this year. Thanks to the performance of the Multi-Pursuit Custom Shields I purchased ahead of time. We went Duck & Goose hunting the first day, out of a pit blind. Usually my ears would ring all night after a day of shooting & sitting next to my nephew blowing his duck & goose calls all day. Not this trip, the Multi-Pursuits did their job. Really a pleasant hunt. The next day was pheasant hunting, and the wind was blowing. I could hear & talk to fellow hunts as the Multi-Pursuits canceled out the wind & shotgun blasts. Another great day. Thanks, again for a great product. Steve

Halfway through duck season and loving my Tetras

I hunt three days every week during the 100 day duck season here in California. I wear my new Tetra multi-pursuit custom shield hearing protectors each day. They are very comfortable and really enhance my hunting experience. I no longer cover my ears when other hunters in my blind are calling birds. And of course the devices soften the sound of the guns being fired. The bonus is hearing the ducks. With my hearing loss I had forgotten what is was like to hear a flight of pintails whistling. So thankful that my wife purchased these for me after seeing the ads in the gun magazines.

Real life experience

Ok her goes. I have used these hearing protection for 3 -4 weeks now And at times I forget they are in They are easy to put in the battery really does last a long time Your shots are truly muted Changing from one mode to the another is as simple as pushing a button The only thing I have noticed which is REALLY nothing is the attached lanyard gets pulled while low crawling or turning your head. I was worried about the squealing and screeching using a face mask But I was worried for nothing ! All in all I am VERY PLEASED TOM
