EAROS x Hendrick Motorsports®

NRR stands for Noise Reduction Rating. It's a measurement used to assess the effectiveness of hearing protection devices.

The NRR of EAROS was determined through laboratory testing according to ANSI S3.19-1974, standards set by the American National Standards Institute (ANSI), using the experimenter-fit protocol.

Our results are available upon request by emailing us at support@earos.com.

Actual noise reduction the user expereinces may vary based on fit and individual ear anatomy. Please note it is important for the user to achieve a seal in order for the product to be effective. Always check the sound levels of your environment to ensure the appropriate NRR of your chosen hearing protection. See our page on how to wear EAROS for a better fit.

Our proprietary, patented sound bore replicates how the inner ear resonates while providing 17+ dB of noise reduction and preserving full audio fidelity.

We worked with top audiologists and vibration engineers from MIT to develop EAROS' patented technology.

1. Sound Quality: Foam earplugs muffle and distort sound. EAROS acoustic filters maintain sound quality, allowing you to enjoy music, communicate with those around you and stay immersed in the sound.
2. Protection: While foam earplugs often have a high NRR rating, they can be quite difficult to insert properly, resulting in less protection than advertised. EAROS has a unique “concha tab” that locks in place, ensuring proper depth of insertion so you can count on getting the seal you need for the product to be effective.
3. Comfort: Foam earplugs are difficult to insert and have a high “occlusion effect” (feeling like you’re underwater). EAROS have a left-right orientation and are contoured to fit the shape of your ears comfortably. We use a soft, silicone-like material for the ear tips to ensure there is no irritation even for extended uses.
4. Style: Foam earplugs stick out of your ears and are goofy-looking, compromising your personal style. EAROS is a sleek, discreet product that looks more like a high-tech wearable than traditional hearing protection so you can be proud to be seen wearing it.
5. Sustainability: Earplugs are a single-use, disposable product that damages the environment every time you buy another pair. In fact, billions are produced and thrown away each year. EAROS, on the other hand, is a high-quality, durable, and reusable product that comes with a carrying pouch so you can reuse it many times over and help the environment.

EAROS is designed to fit most ears and it comes with a set of small, large, and foam ear tips.
