Beltone Promise hearing aids are designed to simulate the way ears naturally process sound. As you encounter different sound environments each day, your hearing aids actually communicate with each other to automatically self-adjust. Sound feels just right and good hearing seems second nature. Our proprietary micro-chip technology makes Beltone Promise hearing aids smarter, smaller and more intuitive than ever before. Simply put them on every morning and forget them. Beltone Promise comes in several popular styles from customized completely-in-the-canal models to behind-the-ear varieties and many more. Every style brings you the latest ways to hear crisp, clear sound, even in noisy places.
