Design and build quality
The K1 Ultra 8K stands out with its refined visual appeal, incorporating real rosewood accent panels on the sides. While the main chassis is constructed from ABS plastic, the keyboard is reinforced with aluminum rails along the front and back edges, providing a sturdy feel. The TKL layout is a popular choice for those who want to save desk space without sacrificing essential navigation keys. Additionally, the board includes a small, programmable knob in the F13 position, which serves as a convenient volume control by default.
Performance and wireless connectivity
Designed for speed and reliability, the K1 Ultra 8K supports an impressive 8 kHz polling rate when used in 2.4 GHz mode. The keyboard utilizes ZMK firmware, which is highly regarded for its power efficiency. Keychron claims that users can achieve up to 490 hours of battery life from the 2,600 mAh battery when using the 2.4 GHz connection with backlighting disabled. For added versatility, the device supports both Bluetooth and 2.4 GHz wireless connections, allowing users to switch between multiple devices seamlessly.
Customization and typing feel
Typing comfort is a priority for the K1 Ultra 8K, which features four layers of internal sound-damping material to minimize noise. Users can choose from three distinct switch types: Keychron Milk POM Red (linear), Brown (tactile), and Banana (fast tactile). The keyboard is fully compatible with the Keychron Launcher software, enabling users to remap keys, create complex macros, and customize the north-facing RGB backlighting to suit their personal style.
