This app transforms your smartphone into a powerful sound amplifier. It allows you to boost surrounding sounds, making conversations clearer, TV audio louder, or serving as a hearing aid. Sound is delivered directly to your connected headphones for an enhanced listening experience.
The app offers an 8x volume boost for significantly louder and clearer audio. It also features background sound amplification, allowing you to continue amplifying sound even while multitasking. The interface is designed to be simple and intuitive for effortless use.
The app is free to download. However, to access premium features and enjoy uninterrupted service, a subscription is required. Subscription details and renewal information are available within the app.
The app requires headphones to function, including Bluetooth headphones for wireless listening. It is designed to work with smartphones to amplify sound from their microphone.
To use the app as a hearing aid, connect your headphones, place your phone near the sound source (like a conversation), and tap the play button. The app will then amplify the sound, making it easier to hear.
