Hear Conversations
More Clearly.
ClearTone transforms standard Bluetooth earbuds into a high-performance personal sound amplifier using on-device neural AI. Built for seniors and adults who deserve clear conversations without expensive hardware.
The ClearVoice Chain
Every stage runs on your phone. No cloud. No recordings. No privacy compromise.
Core Capabilities
Engineered with advanced acoustic algorithms and on-device neural inferencing.
ClearVoice AI Engine
An on-device neural noise-reduction engine, adjustable from 0 to 100%, cuts steady background noise such as fans and air-conditioning in real time — and automatically deepens noise reduction when the speaker is farther away.
Smart Loudness Balancing
Soft voices are automatically lifted and loud sounds kept comfortable — hearing-industry dynamic compression, tuned for real conversations and safe listening.
Real-Time Native Engine
The entire voice chain runs in a native real-time audio pipeline on your phone. Bluetooth earbuds add about 0.4 seconds of delay of their own, so it suits TV and conversations best.
Universal Bluetooth
Works with any standard Bluetooth earbuds or headphones. No proprietary hardware required — accessibility for everyone.
Built for Clarity
Large type, high contrast and a single one-tap start button — available in English and Chinese, designed so seniors can use it without help.
Privacy-First Architecture
All audio processing runs on your phone. Your conversations are never recorded or uploaded.

Frequently Asked Questions
Can regular Bluetooth earbuds really work as a hearing amplifier?
Yes. ClearTone uses your phone's microphone and on-device noise reduction to make speech louder and steady background noise quieter, and streams the audio to any standard Bluetooth earbuds — no special hardware is required.
Is ClearTone a hearing aid?
No. ClearTone is a Personal Sound Amplification Product (PSAP) for everyday conversational assistance. It is not a regulated medical device. If you suspect significant hearing loss, please consult a licensed audiologist.
How much does ClearTone cost compared to hearing aids?
Traditional prescription hearing aids typically cost $3,000–$8,000. ClearTone is a free download on Google Play and the App Store with a 7-day free trial, then a subscription or one-time purchase, and works with the Bluetooth earbuds you already own.
Does ClearTone record or upload my conversations?
No. All audio processing runs on your phone, and your conversations are never recorded, stored or uploaded. The app only sends a device ID for trial and licence checks, plus standard usage statistics on Android.
Is ClearTone easy for an older person to use?
Yes. The main screen is one large start button, with big high-contrast type that respects your phone's font-size setting. The app is available in English and Chinese.
What do I need to get started?
Just an Android phone and any pair of Bluetooth earbuds. Install ClearTone from Google Play, connect your earbuds, and press Start.
