Are these moments familiar to you?
Let‘s walk through a few common scenes — and how we can change them together.
- Family Life
- Social Dining
- Discretion & Comfort
- User Experience
We know that hearing loss isn't just about missing sounds—it's about missing connections with the people and life you love. These common scenes are here to show you: We understand your frustrations, and that's exactly why Waterfall was created.
A Muffled World, Devoid of Detail
Loss of high-frequency sounds and subtle ambient cues results in hearing sound but missing meaning, as if the world's "resolution" has been turned down.
High-Definition Speech Band Remastering
Utilizes sophisticated algorithms to apply intelligent, non-linear compensation and reshaping specifically to the mid-to-high frequencies (1.6kHz - 4kHz) critical for speech clarity, rather than simple amplification, significantly improving speech intelligibility and natural sound quality.
Conversations Lost Behind a Wall of Noise
In bustling environments like restaurants, streets, or gatherings, background noise (chatter, clatter, traffic) creates an intangible "sound wall," isolating you from important conversations and making communication exhausting.
AI Scene-Adaptive Noise Cancellation System
Our proprietary AI chip analyzes the soundscape tens of thousands of times per second, intelligently identifying and suppressing both steady-state and transient non-speech noise (like fan hum or door slams) in real-time, while dynamically protecting and enhancing the human voice frequency band.
The Psychological Burden of a Visible Device
Anxiety about being labeled by wearing a traditional hearing aid leads to social stigma, often causing individuals to choose isolation over using the device in important situations.
Discreet, Fashion-Forward Design
Inspired by stylish neckband headphones, it boasts a sleek, streamlined profile in low-saturation colors (Deep Space Gray, Warm Moon White). The design is indistinguishable from premium wireless earbuds, eliminating psychological barriers to use.
The Hassle of Manual Multi-Scene Adjustments
Manually switching device modes for different environments (quiet, noisy, music, call) is cumbersome. It's difficult to know when to switch, and incorrect settings frequently degrade the experience.
Fully Automatic Smart Ecosystem
Integrated environmental sensors and AI enable automatic detection and adaptation across various scenes from quiet to loud, for true “set-and-forget” operation. Bluetooth 5.3 ensures stable, swift connectivity—automatically linking to your phone when the case opens, with easy multi-device management.
