Keychron Updates Wireless Low-Profile Keyboard Line-Up With New Round Keycap Design

Keychron has been busy lately, releasing a flurry of mechanical, Hall effect, and scissor switch keyboards for everyone from office workers to gamers. The latest announcement from the peripherals company, however, includes three ultraslim wireless keyboards—the B3 Pro, B4 Pro, and B5 Pro—seemingly designed to appeal to the Apple crowd. The updated B Pro series keyboards are available from Keychron's site, with the B3 Pro coming in at $34.99, while the B4 Pro and B5 Pro are $39.99, owing to their larger size. While they don't necessarily have the allure of Keychron's hot-swappable mechanical and Hall effect keyboards, all three keyboards use ZMK firmware, which offers compatibility with Keychron's Launcher web app for customization, macros, and remapping, and impressive battery life, despite the mere 800 mAh batteries inside.
All three keyboards feature round keycaps—a new look for Keychron's low-profile keyboards, and boast wireless connectivity, with 2.4 GHz and Bluetooth 5.2, to support a wide range of devices. They also have built-in switches to select OS and connectivity modes. Keychron claims that the B Pro series keyboards are capable of delivering up to 300 hours of battery life on a single charge, owing to the efficient ZMK firmware. The keyboards themselves are made of ABS plastic and are available in Space Gray or Ivory White, with the round keycaps being made of ABS with a UV printed legend. The B Pro keyboards offer a 9.2 mm front height and a 2.8° typing angle, which should prove to be beneficial from an ergonomics standpoint. The biggest drawbacks of these new keyboards is that they don't offer N-key roll-over—meaning that no more than six keys can be registered at a single time—and that they lack backlighting, so they will not be ideal for those who cannot touch type and often work in dimly lit environments. The only major difference between the three keyboards is the layout. The B3 Pro is a traditional compact 75% layout, while the B4 Pro is a compact 96% keyboard, and the B5 Pro is a full-size board with a row of extra shortcut or macro keys above the num pad.
