Flysound Launches B02 Open-Fit AI Hearing Aid in U.S. Market

The B02 arrives stateside following a successful crowdfunding campaign in Japan that exceeded $3 million. Founder Jory Peng notes that roughly 15% to 20% of individuals with hearing loss cannot utilize standard in-ear models due to medical conditions, while others report issues with moisture buildup and the sensation of ear blockage. By shifting to an open-fit architecture, the device aims to improve long-term wearability for users who typically keep their hearing aids active for over ten hours daily.

Engineers at Flysound utilized a 12nm AI chip to solve the feedback whistling common in open-fit designs. This architecture allows for gains of up to 50 dB by identifying and suppressing potential feedback loops in real time. The device further manages acoustic clarity through internal noise reduction algorithms and impulse noise suppression, keeping internal noise levels below 10 dB. Users can calibrate the device via the Flysound App, which conducts a pure-tone hearing test to generate personalized settings across 16 adjustable channels. For those requiring professional assistance, the platform offers remote fine-tuning sessions covering the 125 Hz to 7,500 Hz range critical for speech recognition.

Beyond core audio performance, the B02 includes an IP55 water-resistance rating and integrated Bluetooth for streaming. The hardware features a dual anti-loss system, incorporating a retention cord and app-based location tracking. Currently available for purchase, the device offers a 50-day trial period and is produced under an ISO 13485-certified quality management system.
