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.

Great fit and easy to wear. Sound reduction in the duck blind is excellent keeping my ability to hear woodies whistle. I think they are a little too loud. I would like to have the conversations not amplified. Range mode would be a good place to decrease the volume of conversation. Otherwise I wish these were available 15 years ago. I will buy some for my son once I think he is responsible enough to not lose them.

Great product

I hate wearing ear pro because it is either cancels normal noises, amplifies unwanted noises (clothes rubbing, etc.), or is bulky and uncomfortable. The Tetra products covers all the bases. I wear them all day while upland and waterfowl hunting. Looking forward to trying them big game hunting next fall after I forgot to slip on my foam plugs in a hurry while shooting my braked 28 Nosler at a buck. I figured I could spend the money now to save my hearing or spend it when I’m older and can’t hear.

Excellent Product

So far I’ve only used them for waterfowl hunting. But after a great day of goose hunting in 15 mph wind, I think it was a great test. I had zero issues with wind, or with the quality of sound while hunting.

OMG moment

This past September I got an email from my friends at Ducks Unlimited and in the articles that usually accompany the email was an article about hearing protection suitable for hunters and sport enthusiasts that was revolutionary. After reading the article and logging onto the Tetra web site for further information I actually had an OMG moment. For years I have been trying numerous electronic models which I returned for various reasons. After procrastinating for several months I stepped up and ordered them. I got an immediate response from customer service explaining their program for fitting the AlphaShield for maximum benefit. I have just finished a five day elk hunt in western Colorado wearing the AlphaShield for all the days in the field. While I did not fire a shot, (not my fault), I will attest to the comfort and acute awareness the earbuds provided. Important note to buyers is to try different ear buds before going out in the field. I did a lot of walking with the AlphaShields prior to leaving on trip.... They are a bit pricey but I don't think you can put a price on your hearing. As an avid motorcycle rider, I once stopped in to a motorcycle shop to buy a new helmet. When looking at the price of a new helmet I was reminded of how you cannot put a price on the value of your HEAD!
