Ducky Mecha SF Pro vs WOBKEY Rainy75 ProWired 65% vs Wireless 75%

The WOBKEY Rainy75 Pro is designed for wireless use, featuring Bluetooth 5.0, a 2.4 GHz dongle mode, and a wired USB-C fallback. Its large 7000mAh battery supports this functionality. The Ducky Mecha SF Pro is a wired-only keyboard.

The WOBKEY Rainy75 Pro supports full key remapping and macro programming through VIA and QMK software. The Ducky Mecha SF Pro listing confirms it is not VIA or QMK compatible, so its key mapping capabilities are limited to any onboard functions it may have.

The Rainy75 Pro uses a gasket mount, where the plate is suspended on rubber gaskets to absorb typing vibrations for a softer, more cushioned feel. The Mecha SF Pro uses a traditional plate mount, where the plate is fixed directly to the case for a firmer, more rigid typing experience.

Based on manufacturer descriptions, the WOBKEY Rainy75 Pro includes several dedicated sound absorption layers: poron, EPMD, and a PET insulation sheet. The Ducky Mecha SF Pro includes a Q-bounce synthetic pad and an EVA sound dampener.

Yes, both the Ducky Mecha SF Pro and the WOBKEY Rainy75 Pro feature hot-swappable PCBs. The Ducky uses Kailh Yellow sockets that accept 3-pin and 5-pin switches, while the WOBKEY's PCB is compatible with plate and PCB mount stabilizers.

A 65% layout, like the Ducky Mecha SF Pro, typically lacks a function row, navigation cluster, and numpad, keeping only alphanumeric keys and arrows. A 75% layout, like the WOBKEY Rainy75 Pro, squeezes in a function row and a compact navigation cluster (like Insert, Delete, etc.) next to the arrows, making it slightly wider but more functional.

The Ducky Mecha SF Pro is more portable due to its smaller 65% footprint. It is also wired-only, so you don't need to carry a wireless dongle or worry about battery charge. The WOBKEY Rainy75 Pro is larger, heavier at 1800g, and requires you to manage its battery for wireless use.

Both keyboards come with double-shot PBT keycaps, which are durable and resist shine. However, they use different profiles (OEM on the Ducky, unspecified on the WOBKEY) and have opposite RGB LED orientations, which affects compatibility with certain aftermarket keycap sets.

The Ducky Mecha SF Pro has north-facing LEDs (at the top of the switch). The WOBKEY Rainy75 Pro has south-facing LEDs (at the bottom). South-facing LEDs avoid interference with the keycap stems on Cherry-profile keycaps, preventing a mushy feel, but may not illuminate shine-through legends as effectively.

The WOBKEY Rainy75 Pro is built with features that prioritize typing feel, including its gasket mount system, FR4 plate, flex-cut PCB, and multiple internal foam layers. This combination is designed to provide a softer, more consistent, and potentially quieter typing experience compared to a stiff plate-mounted board.

The WOBKEY Rainy75 Pro has a built-in 7000mAh rechargeable battery. The manufacturer does not specify exact battery life, but a capacity this large suggests it will last for weeks of typical use. The Ducky Mecha SF Pro does not have a battery, as it is a wired-only keyboard.
