Duck Hunting Ear Protection Waterfowl AlphaShield
$699.00 / Pair Why the price?
TETRA devices use a similar chip and digital noise reduction that you would pay $5,000 for in hearing aids. TETRA devices give you a premium hearing experience, but feel like wearing nothing at all.
Advanced hearing enhancement devices optimized for the most prominent and important sounds for the duck hunter (calls, wings, voices) while providing hearing protection from loud calling and gunshots.
Waterfowl programming also available on Multi-Pursuit AlphaShield.
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 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.

So far they have performed very well I haven’t Duck hunted with them yet I have dove hunted and they worked well
I purchased Tetras to help me hear more while turkey hunting and to help me protect what little hearing I have left. I definitely heard more gobbling with them than without them. It takes a fair amount of time to relearn sounds with Tetras. For instance, the yelp of a hen sounds very different and takes time to recognize with the Tetras.
The representative claimed you could hear normal conversation in the blind, I found the voices to be muffled. When contacting the company by email they failed to reply to my concerns......that said I returned them
These are what I’ve been looking for. Reasonably priced inside the ear hearing protection. I bird hunt a lot. Shooting 2+ cases of shells a year my exposure to shotgun fire is extensive. I had been wearing electronic muffs and just never could get comfortable with them. These are next to ***** and won’t come out of your ears if you tried. There is no clap when they cut off from gunfire. You can hardly tell when they cancel instead of enhance. I do not like that you cannot attach a lanyard and I do not like that there is no on/off switch. You leave the battery door ajar to turn them off which seems cheap even though it works. Good product.
Overall, the alpha shield work well. Normal conversation and having the ability to hear waterfowl works well with these devices. All loud sounds are immediately blocked. A couple of improvements could be made to these devices. 1) The silicon tips slide off very easily and can lodge in your ear when removing the device. Some type of rim on the device might help hold the tip in place better. 2) Also, in order to turn off the device, one has to open the battery compartment door and then store in case. In the open position, the battery doors can easily snag on the mesh inside the storage box. Being able to turn the aid on and off with the Volume/Program Selection button would be very beneficial. Great product overall. Highly recommend
