Turn your phone into a powerful hearing amplifier that captures surrounding audio through your microphone and delivers it clearly to your headphones — whether you're in the same room or need to hear from a distance. This sound booster and megaphone tool gives you instant, adjustable control over your audio environment, making every conversation clearer wherever you are.
🎚️ Precise sound control
Use the volume slider to dial in exactly the level of amplification you need. The live sound level indicator shows incoming audio in real time, so you always know what your microphone is capturing. A simple play button starts and stops your listening session instantly.
🔇 Noise reduction built in
Toggle the noise filter to reduce unwanted background sounds during amplification. Switch between mic sources to find the optimal input for your environment. This audio amplifier isolates voices and important sounds while cutting interference — a true ear speaker experience for any setting.
🎙️ Record and replay
Capture your amplified sessions with the built-in audio recorder. Every recording is saved with playback tiles so you can revisit conversations, lectures, or notes at any time. Start, pause, and stop recordings with full control — students, professionals, and game ear enthusiasts will find this invaluable.
🎧 Connect any headphones
Plug in wired earbuds or pair wirelessly for the clearest possible listening experience. This hearing booster works with the audio equipment you already own — no extra hardware required.
Use this ear amplifier anywhere you need to hear more clearly — crowded places, classrooms, outdoor events, or quiet conversations at a distance. The sound boost adapts to your listening needs with a fast, lightweight interface designed for instant activation.
