Our free online hearing test is designed to provide a highly accurate profile of your hearing levels across the key frequencies needed for hunting. While it does not replace a medical diagnosis from an audiologist, it allows us to fully customize your TETRA devices to your unique hearing needs. For the most accurate results, we recommend taking the test with high-quality headphones in a completely silent room.

TETRA devices are primarily sold and intended to be used as a pair. This is because our technology is designed to provide balanced, 360-degree situational awareness and total protection for both ears. If you have a specific medical need or unique hearing profile, please contact our TETRA Care team to discuss custom options.

5. Submit your results at the end to generate your hearing profile.

If your hearing levels change over time, you can send your devices back to us to be updated with your new hearing profile. We also offer a 30-Day Worry-Free Guarantee that allows for programming adjustments within the first month of ownership to ensure you are completely satisfied with the sound.
