Cearvol Co., Ltd. announced that total sales of its ear-hook and earbud-type sound amplifiers have exceeded 10,000 units on Amazon.co.jp, driven by high usability for seniors.

Cearvol Co., Ltd. is pleased to report the cumulative sales performance of its ear-hook and earbud-type sound amplifier series on Amazon.co.jp.

1. Sales Milestone (Since launch in June 2024) Total Sales: 10,000 units Channels: Amazon.co.jp and others Leveraging its technical expertise as a sound amplifier manufacturer, Cearvol has achieved an overwhelming cost-performance ratio with prices in the 30,000 to 40,000 yen range, compared to traditional hearing aids (100,000 to 300,000 yen). Despite the low price, the products have obtained US FDA medical device certification and offer high functionality, including individual volume adjustment, self-voice volume control, and feedback (howling) suppression.

2. Amazon Ranking Performance The products have achieved top rankings in the sound amplifier category on Amazon.

3. Customer Feedback (Excerpts from Amazon Reviews) One reviewer noted, "Peace of mind for seniors who struggle with smartphones; the dedicated case acts as a remote control for these high-quality sound amplifiers." While small amplifiers often require tiny buttons or smartphone apps, the biggest advantage of this device is that all volume and mode settings can be handled via large physical buttons on the outside of the storage case. This allows even those who struggle with fine manual tasks to adjust the sound intuitively, like using a TV remote. Furthermore, the design—identical to modern wireless earbuds—allows for everyday use outdoors without the negative stigma of a hearing aid.

4. Hygiene and Features The device features an automatic sterilization function when placed in the case, providing peace of mind for daily use.

5. Future Outlook Cearvol remains committed to improving product quality and expanding its lineup to bring the 'joy of hearing' to more people.
