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 simply 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.

Our custom products provide the most personalized fit and protection available.

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.

Custom Shield

Earplugs do what they need to do. I can hear fairly naturally while getting maximum protection when a shot goes off. Only negative I have noticed is that certain noises seam to be amplified too much. For example when hunting our blind on windy days our grass on the blind makes noise as it moves in the wind. This noise seems to be artificially increased to where I have trouble hearing guys on the far end talking.

I bought these for my husband and he loves them! He says they work great and he is very pleased! Tetra customer service is fantastic as well!

The left one never worked so called & then immediately sent it back. We have never heard a word back and it’s been over two weeks since we sent it in. Hunting season here ends tomorrow so we are more than disappointed after spending over $1000….

Customshield 90’s

Well I started out with the alphashield 90’s and they didn’t fit my ears well, I tried them out for week of hunting and sent them back and ordered the customshield 90’s. The fit of the customs are awesome and the sound is actually a lot better too, maybe because of how my ears are and the alpha just didn’t fit me well, also noticed the gun noise is muffled a lot better with the customs. In The end I’m glad I tried both and glad I have the customs. Only reason I put 4 stars instead of 5 is because really we should strive to make everything better and make the sounds of our calling and ducks flying to be just like having nothing in your ears. I am definitely happy with my purchase and Tetras customer service, keep up the good work guys!

This is a duplicate review as the one I posted about my multi-pursuit CustomShields, I bought my wife the Waterfowl CustomShields at the same time. I usually don't leave reviews, but I feel it's important for folks to know our experiences with Tetra. I bought a pair for myself and one for my wife. We both love them. Being able to communicate in the blind and still able to hear the birds all the while protecting our hearing is priceless. I was most worried about durability as we all know the abuse waterfowl gear is subjected to. I have dropped both my CustomShileds in the water at the blind, took them back to to the camp and let them dry on the windowsill, once the moisture was visibly gone, I put batteries back in them and they still worked! This was a year ago and they are still going strong with NO service required. I put a load of our hunting clothes thru the washer and dryer. When I pulled my wife's pants out of the dryer, I felt her CustomShields in the pocket. I just knew they were ruined. I changed the batteries out and they both still worked! This was 3 months ago and they still work the same as the day we got them. I recommend Tetra to all of my hunting buddies.
