K3 HE focuses on magnetic actuation and customizable keystroke behavior, while K3 Ultra 8K targets ultra-low-latency wireless performance and long battery life.
HONG KONG, Feb. 17, 2026 /PRNewswire-PRWeb/ -- Today, Keychron, a leading manufacturer of peripherals compatible with Mac, Windows, and Android, launched a crowdfunding campaign for K3 HE and K3 Ultra 8K, two low-profile custom keyboards designed to balance portability, performance, and control. Built around a slim, 75% layout, travel-ready form factor, both keyboards feature a minimalist industrial design with a metal chassis and natural rosewood frame. Early backers can support the campaign starting at $109.99 USD via Kickstarter.
Why Low-Profile Performance Is Evolving
Low-profile keyboards are increasingly expected to deliver the same responsiveness, customization, and acoustic refinement as full-height designs, without sacrificing portability. Keychron developed these two models to address different user needs within a shared slim platform, combining advanced input technology, and wireless performance.
Across both models, Keychron applies a multi-layer acoustic design engineered specifically for low-profile form factors, using a stacked internal structure of keycap, switch, plate, and sound-absorbing foam to improve typing acoustics without increasing thickness. Both keyboards use LSA low-profile double-shot PBT keycaps, support 2.4 GHz wireless, Bluetooth, and wired connectivity, and can connect to up to three devices across Mac and Windows systems. Core functionality includes hot-swappable switches, dynamic backlit control, and programmable layouts via Keychron Launcher.
"Our goal with these releases is to reduce friction between intent and action," said Paul Tan, Co-founder at Keychron. "Input can be tuned for precision or respond with ultra-low latency during extended wireless use, depending on how the keyboard is configured."
K3 HE - First K3 magnetic-switch keyboard
Designed for competitive and enthusiast gamers, programmers, and power users, this model enables fine-grained control over how each keystroke behaves.
Key capabilities include:
- Hall Effect magnetic sensing with contactless actuation for distance-based trigger and reset
- Adjustable actuation depth and Rapid Trigger for instant key reset
- Last Key Priority (LKP) and Snap Click input modes for resolving simultaneous key presses based on press order or depth
- One key, multiple commands, with gamepad-style analog input support
- Keychron Ultra-fast Lime low-profile magnetic switches
- 2.4 GHz wireless connectivity for responsive, low-latency use
- Programmable via open-source QMK firmware and the Keychron Launcher web app
K3 Ultra 8K - Keychron's top-tier low-profile wireless model with 8000 Hz polling.
Built for users sensitive to latency and responsiveness, this model delivers extreme responsiveness and endurance across gaming, work, and multi-device workflows.
Key capabilities include:
- 8,000 Hz wireless polling rate with ultra-low latency input response as low as 0.125 milliseconds
- Up to 550 hours of battery life in 2.4 GHz wireless mode using efficient ZMK firmware
- Keychron low-profile Milk POM mechanical switches, pre-lubed for consistency and durability
- Programmable via the Keychron Launcher web app for remapping, macros, and shortcuts
"Low-profile no longer has to mean limited," continued Tan. "With these K3 models, users can choose between magnetic precision or high-performance wireless input while keeping the same slim form factor and build quality."
