Redbean Launches the Innovative A39R Quantum Mouse on Makuake

The Redbean Quantum Scroll Portable Mouse: A39R Launching Soon

Redbean, a South Korean gadget brand established in June 2017, is set to launch its next-generation wireless mouse, the A39R, on Makuake starting October 15, 2025. Despite being a small team, Redbean is fueled by a passion for gadget development, and it has consistently garnered attention in South Korea’s crowdfunding scene, thanks to the support from numerous users.

What Makes the A39R Unique?

The A39R, known as the Redbean Quantum Scroll Portable Mouse, boasts several cutting-edge features designed to elevate user experience. It's equipped with ultra-fast and precise Quantum Scroll technology, a versatile tilt wheel for horizontal movement, and dedicated buttons for forward and backward navigation. The mouse is powered by a USB-C rechargeable battery, eliminating the need for disposable batteries, and it offers an eco-friendly, lightweight design that allows for prolonged use of up to three months on a single charge.

Product Features

1. Infinite Scrolling and Precision Control
The A39R includes Redbean's proprietary Quantum Scroll technology, allowing users to scroll through pages at lightning speed. The mouse also supports pixel-perfect precision, striking a perfect balance between speed and accuracy.

2. Tilt Wheel and Navigation Buttons
With the tilt wheel, users can effortlessly scroll both vertically and horizontally, making it especially efficient for tasks like Excel spreadsheets, design work, and web browsing, where moving backward and forward is just a click away.

3. Quiet Clicking
Every click with the A39R is designed to be silent. The main and side buttons are engineered to avoid disturbing others in quiet places like cafes and libraries, allowing for a more focused working environment.

4. USB-C Rechargeable and Sustainable
The mouse does away with the need for batteries, using a USB-C charging method instead. This not only reduces weight for easier portability but also consciously minimizes battery waste, with up to three months of continuous use available from one charge.

5. Multi-Device Compatibility
The A39R can connect to up to three devices simultaneously, with Bluetooth support for two devices and one for a USB receiver. Its automatic recognition of both Mac and Windows operating systems means users can switch seamlessly without complicated setup procedures.

Background of Development

Since its inception in 2017, Redbean has been dedicated to discovering the “familiar inconveniences” in daily life and resolving them smartly. The brand’s mantra, “No Extras, Just Re'd,” encapsulates this philosophy. They believe that by focusing solely on what is necessary, one can achieve a more comfortable and efficient daily routine.
The product philosophy embodied by the A39R reflects the process of Rediscovering, Redefining, and Redesigning everyday convenience. Redbean’s aim is to not just create ordinary peripherals but to develop products that enrich the work experience, striving towards transforming desks into spaces of functionality and aesthetic appeal, or what they call “desk-teria.”

Future Prospects

Following the crowdfunding phase, the A39R will also be available through domestic e-commerce platforms and retail stores, with potential international offerings on the horizon. The company is committed to incorporating user feedback to continue developing devices that improve the workspace.
