NOT SURE? TRY OUR Product Selector Tool

In case there is any confusion, let’s set the record straight: duck hunting with unprotected ears causes hearing loss. As hearing doctors at TETRA, we see what years of waterfowl hunting does to our patients. Recent studies show that people with hearing loss are more likely to develop dementia, Alzheimers and other chronic health problems.* Hearing loss impacts overall health and wellness, and ruins the hunting experience.

So why do 86% of hunters NOT use hearing protection? Previous products have distorted the sound of the call, either over-amplified everything or blocked out your surroundings, and just weren’t comfortable. We solved those problems with the TETRA Shield Series. Using our patent-pending Specialized Target Optimization (STO) voices and calling are clear and natural while AlphaShield Compression reduces loud sounds to safe levels.

AlphaShield is a small, extremely comfortable, one-size-fits-all solution. AlphaShield provides great comfort and great protection without the need for an ear impression.


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, wood duck squeals, whistling wings, and mallard drakes are all easily audible.

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.

Waterfowl Alpha Shield

William was a big help getting these squared away after I struggled with the online hearing test. I went to Costco and got a detailed hearing test, free to members, and I'm getting used to the devices. I was pleased with the customer service and recommend the getting these.

Game changing

I’m 36 years old and have been shooting guns competitively and recreationally since I could hold a long gun. I’ve tried several other brands and products. NOTHING even comes close to the comfort and performance of my alpha shields. I have some significant hearing loss in my left ear and I never realized how much the blast from a shotgun was effecting my hunting. Calling took a little getting used to but anyone who’s proficient with a call the adjustment is small. Thanks for making such a quality product!

Waterfowl AlphaShield has increased my hunting experience.

These are more than expected. Wind does not get picked up like my old “ Game Ears”. The loud noises are shut out completely but I can hear other things that are going on. Totally comfortable even after hunting all day. Also they don’t pull out accidentally when removing my head net. Batteries last longer than the other brand. Yes they are more expensive but worth the price for me. Thanks for making a superior product.

Alphashield 90

Absolutely love these, the best purchase I have ever made. The wind cancellation makes being out on big water with high winds is amazing. Can still hear calling, wings, buddies talking to you. They completely silence your shooting. The only thing I would change is a way to turn off the device, but overall a tremendous product.

Best ear pro I’ve had

Great experience so far. I’ve had several different products from other companies but these are superior. Only complaint is there isn’t an on/off function w out taking the batteries out. I hunted in a 50mph wind in South Dakota, and deer hunting in south Texas the ear pro was effective in the wind, comfortable and easy to use so I found my self using them more.
