ANC Hearing Test
Take control of your hearing health with clinically validated, app-based test—anytime, anywhere, right from your smartphone.
Rehear’s app-based hearing test puts you in control of your hearing health—anytime, anywhere. Clinically validated and smartphone-ready, it delivers accurate, personalized results without the need for specialized equipment or a sound booth.
Whether you're at home, at work, or on the move, our intuitive interface guides you step by step, making it easy for anyone—even first-time users—to complete a hearing test with confidence.
Designed for real-world environments and real people, Rehear brings clinical precision to the palm of your hand—so you can take the first step toward better hearing, on your terms.
ANC-Driven Accuracy in Audiometric Testing
Our ANC technology intelligently boosts noise reduction performance, dramatically improving the signal-to-noise ratio for pure tone detection. With ANC activated, users can enjoy a quiet testing environment comparable to that of a professional soundproof booth.
AI Hearing Compensation・Personalized Audio Adjustment
Powered by advanced AI algorithms, our solution replaces traditional frequency-based adjustments with dynamic, data-driven compensation—dramatically improving audio fidelity.
Once a user’s individual hearing profile is obtained, real-time compensation is applied within just 150 milliseconds, ensuring an immediate and seamless listening experience.
Even during complex multi-channel adjustments, the system maintains zero distortion, preserving every nuance for the most natural and authentic sound.
RehearFit™ (AI Auto-REM)
AI-Powered Real-Ear Measurement for Truly Personalized Hearing
RehearFit™ leverages advanced AI-based parameter calibration to deliver precise, individualized hearing compensation—anytime, anywhere. In just 13 seconds, the mobile AI algorithm analyzes each user’s unique ear canal acoustics, automatically adjusting gain to optimize sound reception at the eardrum.
By replicating measurements equivalent to those taken 26–28 mm deep inside the ear canal using traditional professional equipment, RehearFit™ achieves clinical-grade precision—without the need for probe tubes or audiologist intervention.
The result? A fast, effortless, and highly personalized calibration process that ensures clearer, more accurate sound tailored to each individual.
Superior Noise Reduction for Music and Calls
Powerful Noise Cancellation Without the Pressure — A More Comfortable Way to Listen
Rehear’s AI-adaptive noise reduction technology actively cancels up to 40 dB of ambient noise, delivering strong hearing protection without sacrificing comfort. Unlike traditional earbuds that create a “plugged-up” or stuffy sensation, Rehear overcomes the occlusion effect, preserving natural sound transparency.
Even in noise-cancelling mode, environmental sounds and speech remain clear—so whether you're having a conversation, taking a call, or simply enjoying your surroundings, you'll experience effective noise reduction with effortless comfort and natural awareness.
Smart Scene Switching for Clearer Music and Calls
Whether you're commuting, working, or on a call, Rehear intelligently adapts to your surroundings, automatically selecting the optimal noise reduction mode to deliver clearer audio and a better listening experience across all scenarios.
