ANC Hearing Test
Take control of your hearing health with clinically validated, app-based test—anytime, anywhere, right from your smartphone.
Rehear's app puts you in control of your hearing health. It is clinically validated and smartphone-ready, delivering accurate, personalized results without the need for specialized equipment or a sound booth.
Whether you're at home, at work, or on the go, our intuitive interface will guide you through the process step by step. It's so easy that even first-time users can complete a hearing test with confidence.
Designed for real-world environments and real people, Rehear brings clinical precision to your fingertips, so you can take the first step toward better hearing on your terms.
Accurate Audiometric Testing with ANC
Our ANC technology intelligently enhances noise reduction performance, significantly improving the signal-to-noise ratio for pure tone detection. With ANC activated, users can enjoy a quiet testing environment similar to a professional soundproof booth.
AI Hearing Compensation・Personalized Audio Adjustment
Our solution uses advanced AI algorithms to replace 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 in just 150 milliseconds, for an immediate and seamless listening experience.
The system maintains zero distortion even during complex multi-channel adjustments, preserving every nuance for the most natural and authentic sound.
RehearFit™ (AI Auto-REM)
AI-Powered Real-Ear Measurement for Truly Personalized Hearing
RehearFit™ uses advanced, AI-based parameter calibration to provide precise, personalized hearing compensation anytime, anywhere. In just 15 seconds, the mobile AI algorithm analyzes each user’s unique ear canal acoustics and automatically adjusts the gain to optimize sound reception at the eardrum.
RehearFit™ achieves clinical-grade precision by replicating measurements equivalent to those taken 26–28 mm deep inside the ear canal using traditional professional equipment—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 in 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, providing strong hearing protection without compromising comfort. Unlike traditional earbuds, which create a “plugged-up” or stuffy sensation, Rehear overcomes the occlusion effect, to preserve natural sound transparency.
Even in noise-canceling mode, environmental sounds and speech remain clear, so you'll experience effective noise reduction with effortless comfort and natural awareness, whether you're having a conversation, taking a call, or simply enjoying your surroundings.
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 in every scenario.
High-Fidelity Audio in Quiet Environments
Ultra-Low Latency. Ultra-High Resolution. Truly Immersive.
Rehear is engineered to preserve every detail of sound—even in the quietest settings.
Ultra-Low Latency — Just 0.2 ms
Even the slightest delay can disrupt speech perception. Rehear minimizes latency to an industry-leading 0.2 milliseconds, keeping speech and sound perfectly synchronized for a natural, lifelike experience.
Ultra-High Sampling Rate — 625 kHz
With a 625 kHz sampling rate, Rehear captures every nuance of voice and music, delivering vibrant, crystal-clear audio. The result is stunning sound fidelity with rich detail and precise rhythm—whether you're in conversation or immersed in your favorite song.
Enjoy high-resolution audio without compromise—anytime, anywhere.
Clearer Conversations in Noisy Environments
Low Latency. High Clarity. Smarter Noise Reduction.
Rehear ensures seamless communication—even in challenging acoustic settings.
Low Latency — Just 3 ms
With latency under 3 milliseconds for in-ear audio processing, Rehear minimizes lag and artifacts during real-time conversations, preserving voice clarity.
Smarter Noise Reduction with AI
Unlike traditional NAL-R processing, Rehear’s AI algorithm intelligently targets and suppresses low-frequency background noise. This allows face-to-face speech to emerge with striking clarity, even in noisy environments.
Stay focused on the conversation, not the noise.
