OTC Receiver-in-Canal Hearing Aids

Empower your hearing with the help of “machine learning” technology: Sontro’s intelligent hearing aids adjust for direction and volume for exceptional sound quality.

For Your Active Lifestyle

Sontro over-the-counter (OTC) hearing aids need no prescription, yet they give you advanced controls to provide a comfortable and effective hearing experience. Fitting snugly and discreetly behind your ears, these small devices are sturdy, sweat-resistant and comfortable to wear in every setting.

You’re In Control

With Sontro’s easy-to-use app, you can customize your personal settings and make changes when you need to. Just by touching the controls on your mobile phone, you can quickly raise and lower different frequencies — to better hear higher-pitched voices or enjoy stronger base tones in music.

Follow the

When you’re with a group of people, the sound of speech may come from all directions. Sontro OTC hearing aids use directional microphones and advanced signal processing to manage sound coming from different directions.

Called Adaptive Directionality, this powerful feature allows you to follow conversations more easily in every situation.

Hear What
Matters Most

Sontro OTC hearing aids process sound using a sophisticated technology called Wide Dynamic Range Compression. This helps expand your hearing range across 16 channels. It makes soft sounds louder and loud sounds more comfortable, giving you easier listening and finer sound quality.

Adapt to Every Environment

Whether you’re in a crowded restaurant or on a windy beach, Sontro OTC hearing aids intelligently monitor your environment and automatically select the most appropriate sound mode. This helps you hear your best, adapting seamlessly as you move from quiet to noisy listening situations.
