Following the recent launch of the Keychron K4 Ultra and K10 Ultra, the accessory maker has officially launched the new K5 Ultra 8K, a low-profile wireless mechanical keyboard with a full 100% layout and sleek cherry wood accents. The K5 Ultra is the latest version of the low-profile K Ultra-series, which means it uses the same ZMK firmware and has the same 2.4 GHz and Bluetooth 5.2 wireless connectivity as the previously announced K3 Ultra had. The K5 Ultra has launched with an MSRP of $114.99, and is available in black on the Keychron online store or on Amazon . The K5 Ultra is also capable of refresh rates of up to 8 kHz over both the wired USB Type-C connection and the 2.4 GHz connection. Wireless connectivity is powered by a 2,400 mAh battery, and Keychron cites 370 hours of use from a single charge with the backlighting disabled and the keyboard running at an 8 kHz polling rate.

The Keychron K5 Ultra uses a proper full-size layout and includes both a programmable knob above the backspace key and a macro row above the num pad. The K5 Ultra is available with Keychron's relatively new Milk POM low-profile switches—which follow the Gateron Low-Profile 2.0 pin layout—in three switch flavors. Milk POM Reds are linear with a 45 gf actuation force, while the Milk POM Browns are tactile with a 50 gf actuation force, and the Milk POM Banana switches are a strong tactile switch with 57 gf actuation force. All three switches have 3.1 mm of total travel, but the Reds have 1.3 mm of pre-travel, while the two tactile varieties have 1.7 mm pre-travel. The K5 Ultra measures in at 436.6 x 128.29 mm and has a 15.55 mm front height. It also features two-stage flip-out feet for different typing angles.
