Keychron has expanded its low-profile Ultra series with the Keychron K5 Ultra 8K, a full-size wireless mechanical keyboard that adds rose wood side panels to the familiar formula. Priced at $114.99 and available now in black through Keychron's store and Amazon, the K5 Ultra keeps the ZMK firmware foundation and dual 2.4 GHz/Bluetooth 5.2 connectivity introduced on the K3 Ultra, but stretches the layout to 100 percent with a programmable knob above backspace and a dedicated macro row above the numpad.

The headline feature is an 8 kHz polling rate that works over both wired USB-C and the 2.4 GHz dongle — a spec Keychron backs with a 2,400 mAh battery rated for 370 hours at that speed with backlighting off. Switch duties fall to the company's Milk POM low-profile line, offered in linear Red (45 gf), tactile Brown (50 gf), and heavy tactile Banana (57 gf) variants, all sharing 3.1 mm total travel on the Gateron Low-Profile 2.0 pin layout.

Build quality mixes ABS plastic with metal top and bottom rails, while LSA-profile double-shot PBT keycaps should resist shine. North-facing RGB and browser-based remapping via Keychron Launcher round out the package. At 15.55 mm front height with two-stage feet, the K5 Ultra targets users who want full-size functionality without the bulk of traditional mechanical boards, positioning wood accents as a differentiator in a segment dominated by plastic and aluminum.
