ENNO is a professional manufacturer specializing in the research, development, and production of hearing aids. Our core team has over a decade of industry experience. We operate our own production facilities and standardized workshops, and thanks to our solid R&D and manufacturing capabilities, we have earned numerous authoritative certifications, including National High-Tech Enterprise and "Specialized, Refined, and Innovative" SME status in China, as well as international certifications such as ISO13485, FDA, and CE. From R&D through to production, we maintain strict control over the entire process, ensuring consistent product quality and compliance.
Through in-depth market research, we have identified two major pain points commonly experienced by users: first, feedback during wear often causes "howling," which severely interferes with listening clarity; second, traditional in-ear designs can lead to a sense of stuffiness and pressure, making users feel self-conscious in social situations.
To address these challenges, our R&D team conducted targeted research and introduced innovative solutions. For feedback howling, we distinguish between "internal feedback" and "external feedback." Internal feedback is blocked at the source through physical isolation technology, while external feedback is managed using a "physical seal + hardware-software collaboration" approach, combined with our self-developed algorithm for real-time suppression, ensuring clear and pure sound output.
In terms of wearing comfort, we have independently designed an ergonomic earpiece that conforms to the natural curve of the ear canal, significantly reducing feelings of stuffiness and pressure and ensuring comfort even during extended wear.
We especially recommend our patented product—the "No-Block, No-Howl" Earbud. This product has been granted a patent certificate by the China National Intellectual Property Administration. Compared to traditional in-ear earbuds, its design is more minimalist and discreet, effectively alleviating social concerns and boosting wearer confidence. It excels in both "no howling" and "high comfort," earning widespread recognition not only in the Chinese market but also maintaining strong sales in Japan, where it has received a great deal of positive user feedback.
Looking ahead, ENNO will continue to focus on our users, constantly refining our products and services. We sincerely look forward to collaborating with you to create mutual value!
