Keychron continues to impress in the crowded mechanical keyboard market with the K8 Ultra 8K, a versatile and robust option that builds upon the company's established formula of delivering high-value peripherals. This latest TKL (tenkeyless) model offers a sturdy aluminum top case, durable PBT keycaps, and flexible connectivity, all at a surprisingly affordable price.
The keyboard features a substantial aluminum top piece, though the underside is made of a doubleshot ABS portion. Despite this construction, the K8 Ultra 8K feels incredibly solid, weighing in at 1.299 kg, which contributes to its weapon-like sturdiness. The doubleshot PBT keycaps are durable and feature an OSA profile, offering a more spherical top edge that aids finger placement during typing. The TKL layout is a practical choice, maintaining essential keys while freeing up desk space, further enhanced by narrow bezels.
While some users might miss the dedicated rotary volume knob found on other Keychron models, volume control is accessible via Fn key combinations with F11 and F12. Connectivity options are plentiful, with a USB-C port for wired use and a switch for easily toggling between Bluetooth 5.2 and 2.4 GHz wireless. The keyboard pairs effortlessly with both Windows and macOS devices, demonstrating reliable performance across different connection methods.
A significant upgrade is the K8 Ultra 8K's battery life, reportedly up to 760 hours with no RGB lighting enabled, and 225 hours with the lighting at its lowest setting. This extended endurance is attributed to the new ZMK firmware, specifically designed for wireless connectivity, which offers a substantial improvement over older models that utilized the QMK standard. The keyboard also supports an 8000 Hz polling rate over both 2.4 GHz wireless and USB-C, a feature typically found in high-end gaming peripherals, though it lacks other advanced gaming features like rapid trigger.
Configuration is handled through Keychron's web-based Launcher software, a lightweight tool for customizing macros, remapping keys, and adjusting the 22 available RGB lighting presets. The keyboard utilizes Keychron's new Apex switches, featuring a box stem design aimed at reducing key wobble. Available in Red (linear, 45g actuation), Brown (soft tactile, 50g), and Banana (heavier soft tactile, 55g), the switches offer different typing experiences. The review sample's Brown switches were noted as being on the subtle side, with a preference expressed for a more pronounced tactile bump or a heavier actuation force, which the Banana switches might provide. Despite this, the internal sound dampening and factory-lubed switches contribute to a pleasing acoustic profile, though the metal case can cause some high-pitched resonance.
For those whose stock switches aren't to their liking, the K8 Ultra 8K is hot-swappable, supporting both 3- and 5-pin switches, and includes the necessary tools for easy replacement. This flexibility, combined with its robust build and excellent battery performance, makes the $120 price point particularly noteworthy. When compared to competitors like the Asus ROG Strix Scope II 96 Wireless, which is more expensive and offers a less optimal software experience, the Keychron K8 Ultra 8K presents a highly competitive package. It stands as a solid, dependable, and versatile mechanical keyboard that largely hits all the right notes for its price.
