A compact, high-efficiency hearing aid that excels at isolating speech through its dedicated AI-driven neural processor.
ReSound Vivia 9 Review: Intelligent Focus Through Augmented Intelligence
The ReSound Vivia 9 is GN Group's flagship response to the AI revolution in hearing health. Released in early 2025, it differentiates itself from earlier platforms by incorporating a dedicated Deep Neural Network (DNN) chip. This processor has been trained on over 13.5 million spoken sentences, allowing the device to proactively identify and separate human speech from environmental noise with 17x greater efficiency than previous generations. Clinical evaluations show that the Vivia 9's 'Ensuite Directionality III' provides a comprehensive 360-degree soundscape, ensuring users aren't 'blinded' to sounds coming from behind or the sides. Despite the dual-chip architecture, ReSound has managed to maintain the 'microRIE' form factor, making it one of the most discreet premium devices on the market. It also leads the industry in connectivity, featuring native Bluetooth 5.4 with LE Audio and Auracast support.
