“Lowering the actuation depth improved my reaction time in competitive games. Analog mode in racing titles feels surprisingly natural. The mouse glide is smooth.”
“I thought the macro didn't have infinite repetitions, but there are no helpful images anywhere on the internet. I still haven't found the answer.”

Keychron K2 HE vs WOBKEY Rainy75 Pro: your questions
The WOBKEY Rainy75 Pro has a larger 7000mAh battery, which should provide longer wireless operating time compared to the Keychron K2 HE's 4000mAh battery. Vendor reviews for the Rainy75 Pro mention the battery lasting up to two weeks with lights on.
No, not interchangeably. The Keychron K2 HE is hot-swappable but only compatible with Gateron double-rail magnetic switches. The WOBKEY Rainy75 Pro has a standard hot-swap PCB that accepts common 3-pin and 5-pin mechanical switches.
The WOBKEY Rainy75 Pro is likely better suited for a quiet office. Its gasket mount design, FR4 plate, and multiple sound absorption layers (poron, EPDM, PET) are engineered to produce a dampened, pleasant typing sound right out of the box.
Yes, both the Keychron K2 HE and the WOBKEY Rainy75 Pro list Mac and Windows support. The Keychron K2 HE specifically includes keycaps for both operating systems and a system toggle switch.
The Keychron K2 HE uses a tray mount with an aluminum plate, offering a firmer feel centered on its magnetic switch characteristics. The Rainy75 Pro uses a gasket mount with an FR4 plate and flex cuts, designed to provide a softer, more cushioned and flexible typing experience.
Yes, both keyboards are programmable. The Keychron K2 HE supports QMK and its own Launcher web app. The WOBKEY Rainy75 Pro is programmable with VIA software over wired and 2.4 GHz connections.
The Keychron K2 HE is significantly more portable. It weighs 980g compared to the Rainy75 Pro's 1800g, and its dimensions are more compact (45 x 150 x 155 mm vs 30 x 320 x 150 mm), making it easier to carry in a bag.
According to Keychron, the K2 HE's magnetic switches offer adjustable actuation points (0.2-3.8mm), Rapid Trigger, Analog Mode for variable input, Last Key Priority for gaming, and Dynamic Keystrokes for assigning multiple actions per key based on press depth.
The Keychron K2 HE uses north-facing RGB LEDs, which can interfere with the legends on some Cherry-profile keycaps. The WOBKEY Rainy75 Pro uses south-facing RGB LEDs, which avoids this interference and is preferred for Cherry-profile keycap compatibility.
Some user reviews for the Keychron K2 HE mention keys failing or sticking after long-term use. For the WOBKEY Rainy75 Pro, a vendor review noted issues with 2.4GHz wireless interference causing disconnections, though Bluetooth worked well.
The vendor descriptions do not provide a full list of included accessories in the box. The Keychron product page shows optional accessories for sale like a silicone palm rest, coiled aviator cables, and extra keycap sets.
