Product Overview
China's self-programmable hearing solution designed for clinicians and advanced users who require a programmable, hygienic device with high ingress protection and advanced noise management.

Core Features

• Professional Programmable DSP: 16-channel WDRC with 4 listening programs (Standard, Restaurant, Outdoor, Music) for a configurable hearing profile.
• UV Sanitation Charging Case: Integrated UV-C technology eliminates up to 95.0% of bacteria including E. coli and Staphylococcus aureus.
• IP68 Waterproof & Dustproof: Highest ingress protection for use in varied clinical and field environments.
• AI-Powered Noise Reduction: Intelligent noise management that enhances speech clarity while reducing background noise; AI cancellation up to 21 dB.
• Bluetooth Connectivity & App Control: Bluetooth 5.0 for direct connection to iOS and Android devices with a dedicated control app.
• Fast Charging & Extended Battery: 15-minute quick charge provides approximately 8 hours of use; portable charging case extends total usage up to 72 hours.
• Smart Feedback Cancellation: Advanced feedback suppression algorithm reduces whistling and improves comfort.
• Self-Programmable Interface: User-accessible programming allows personalized adjustments without immediate clinician reprogramming.

Technology Details & Advantages

• Multidimensional Adaptive Directionality: Fixed cardioid and adaptive hypercardioid modes focus on speech signals; fixed cardioid yields ~10 dB stronger front signal capture versus rear.
• AI-Powered Noise Reduction System: Detects speech presence and preserves speech energy while attenuating non-speech noise; in absence of speech, enters deeper noise reduction to lower ambient noise without causing unstable volume shifts.
• Smart Feedback Cancellation Technology: Real-time monitoring of feedback-prone frequencies with intelligent reverse-wave generation to cancel feedback proactively, benefiting first-time users and those with well-sealed ear canals.
• Professional-Grade Hardware & Reliability: Uses Knowles receivers with validated durability (5,000 swing cycles, ≥15 N pull tests). Supplied with multiple earbud types (closed, open, power) and Sport Lock earbud locks for stable retention.

Experimental Data & Validation

• Verified Acoustic Performance: Fixed cardioid mode demonstrates a 10 dB front-to-rear difference, exceeding common industry baselines; adaptive hypercardioid maintains consistent 70 dB perception across complex source configurations.
• AI Noise Cancellation: Laboratory tests show up to 21 dB noise reduction, improving intelligibility in noisy environments.
• UV Sanitation Efficacy: Independent testing verifies up to 95.0% elimination rate against test microorganisms including Escherichia coli and Staphylococcus aureus using the integrated UV sterilization case.
