Sanwa Supply launches two new lightweight silent ergonomic mice, featuring Bluetooth and 2.4GHz wireless support, designed to reduce wrist strain and noise during prolonged use, with battery life lasting up to 250 days.
Sanwa Supply has introduced two new silent ergonomic mice aimed at users who want a lighter design for long sessions at a desk. The MA-EBBS536BL uses Bluetooth only, while the MA-EWBS536BL adds 2.4GHz wireless support. According to the company’s product information and related coverage, both models weigh 62g, which Sanwa says is about 40% less than its conventional ergonomic mice.
The design is built around a grip that rests the hand more naturally from the side rather than forcing a flatter, top-down hold. In practical terms, that should help reduce wrist twisting during extended use. Sanwa also says all buttons are quiet, making the mice better suited to office environments, late-night work or shared spaces where click noise can be distracting.
Connectivity is the main difference between the two versions. The MA-EBBS536BL supports Bluetooth 5.4, while the MA-EWBS536BL can switch between Bluetooth and 2.4GHz wireless, which may be more convenient for people who work across several devices. Both models charge over USB Type-C, can be used while charging and are rated for up to 250 days on a full charge, according to Sanwa.
The mice also include back and forward buttons positioned beneath the thumb, a layout intended to speed up browser navigation. Both models offer sensitivity adjustment up to 4,800 DPI, which should make them usable on larger or ultrawide displays. Sanwa says its Mouse Utility software can also remap the scroll wheel button and side buttons, giving users more control over how the device behaves.
