An industry-first universal fit with adjustable tips for extreme comfort.

Clear communication and environmental awareness are an absolute necessity on the range. At TETRA, we’ve analyzed the most critical sounds for the competitive and recreational shooter and programmed those into each device. Using our proprietary Specialized Target Optimization™ technology, range commands, instructors, students, and voices of shooting partners are clear. Surrounding environmental sounds are natural, while maintaining appropriate hearing protection for the shooter.

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.

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 environment. With our AlphaShield Range products, STO provides clear voices for your shooting partners and range officers, while maintaining natural levels of sounds for the environment around you.

All of our products use advanced digital processing to instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer protection based on the fit of the device. 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 talking with shooting 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.

For Coaches, Trappers, and Parents

In just one weekend of shooting, your ears – and your shooter’s – will be exposed to thousands of dangerous gun blasts. That’s more than the average person experiences in a lifetime.

As a coach or parent, you need to communicate effectively with your shooter before he/she steps into the box. As a trapper, you need to hear when the shooter signals “pull,” and be able to communicate important course rules and regulations. And most importantly, you need to protect your hearing.

Until now, spending the entire day hearing naturally, communicating efficiently and protecting the ear with a device that fits comfortably in the ear simply was not possible. At TETRA, we’ve perfected both protection and hearing for the ultimate sound experience for the shooting sports.

If you’re concerned that you or your shooter may have hearing damage, please take our ONLINE HEARING TEST, and we’ll connect you to one of our co-founders. They are professional audiologists, and want nothing more than to see you and your shooter live a long, healthy life with the best hearing possible.

“TETRA gives me a needed choice that I’ve never had before. As a shooter, in some situations complete silence is preferred. However, in other situations, I prefer enhanced hearing that will provide an advantage over my competition. TETRA gives me the ability to choose what I want to hear. The versatility of these earplugs exceeded my expectations. I can hardly wait to use these in competition.”


“Parental communication has been a challenge up until now. TETRA provides the protection that I need while allowing me to hear what I need to hear. I don’t even have to think about it. I can easily communicate with my child without removing ear protection. TETRA’s hearing devices have allowed the world around me to come alive while at the same time, given me confidence that I’m protecting my hearing with the best. Protecting my hearing and being able to communicate doesn’t have to be frustrating anymore.”
