ASUS TUF Gaming K4 Magnetic packs Hall-effect controls into a compact 75% wired board. Japan gets black and white versions at ¥16,980, roughly $108. Each magnetic key can trigger anywhere from 0.1mm through 3.3mm, with 0.01mm adjustment steps.
Rapid Trigger resets inputs during key return, while Speed Tap favors whichever opposing direction was pressed last. A hardware control can enable Rapid Trigger without software. USB polling reaches 8,000Hz, and ASUS claims response as low as 0.125ms, though that figure covers keyboard polling rather than full game delay.
Arrow keys, basic navigation buttons, and a volume dial stay on board. Double-shot PBT caps sit above per-key Aura Sync RGB. Inside, a gasket design uses five damping layers with PORON and silicone.
The case measures 324 × 156 × 40mm and weighs 1,090g. A braided USB-A to USB-C lead detaches. Switches can be swapped, although magnetic replacements need compatibility checks before purchase.
