ListenOS: Hearing Aid App

ListenOS is a personal sound amplifier and hearing app designed to help you hear conversations, TV, and ambient sounds more clearly. Whether you are in a noisy restaurant or trying to follow a lecture, the app uses your headphones to boost the sounds you need to hear.

Tailored to Your Ears Everyone hears differently. ListenOS includes a quick, built-in hearing test you can take at home. Based on your results, the app automatically adjusts the audio settings for each ear independently to give you a balanced, natural sound profile. You can also save and track your hearing changes over time by syncing with Apple HealthKit.

Key Features

Sound Amplification: Boost ambient sounds by up to 11x, making quiet voices and distant sounds much easier to understand.

Built-in Equalizer: Fine-tune specific audio frequencies to your liking, allowing you to boost high-pitched speech or increase low-end warmth for maximum clarity.

Advanced Noise Reduction: Filter out distracting background noise, wind, and environmental clutter so you can focus entirely on human speech.

4 Preset Modes: Quickly switch between audio settings tailored for different everyday environments.

Bluetooth Support: Works seamlessly with your favorite wireless headphones, including AirPods.

Built-in Music Player: Listen to your music through the app with audio settings and equalizer profiles optimized for your hearing.

Unlimited Custom Profiles: Save and name your own tailored audio and equalizer setups for specific places like your office or a favorite cafe.

Tips for New Users Getting used to an audio amplifier takes time. At first, everyday sounds like footsteps, paper rustling, or a refrigerator humming might seem unusually loud or sharp. This is completely normal. We recommend starting in quiet environments, using the built-in noise reduction settings, and letting your ears adjust gradually over a few weeks using our guided 4-week adaptation course.

Please Note Due to standard hardware limitations, using wireless Bluetooth headphones may cause a slight audio delay or echo.

Disclaimer ListenOS is not a certified medical device or a hearing aid substitute. The built-in test is only used to configure the app's audio settings. If you have medical concerns about your hearing, please consult an audiologist or healthcare professional.
