Womier SK75 75% Wireless Mechanical Keyboard - Creamy Aluminum Build

In this review the Womier SK75 stands out as a 75% wireless mechanical keyboard aimed at gamers and power users who want a substantial, customizable board without a full-size footprint. The single biggest reason to consider it is its combination of a sparkling full aluminum alloy shell and an internal five-layer acoustic design that together deliver a sturdy feel and a pleasing, refined typing sound. For those who value build quality, hot-swap customization and robust wireless flexibility, this keyboard offers a lot for the price.

Key Features

• Full aluminum shell: The glitter-flecked aluminum alloy body provides a solid, durable foundation that resists daily wear and creates a premium heft and stability for every stroke.
• Five-layer acoustic padding: PORON plate foam, IXPE switch pad, PET acoustic pad, EPDM case foam and PET insulation film combine to produce a crisp, refined sound and reduced case resonance.
• VIA programmable: Open source VIA support lets users remap keys and create custom layouts and backlight effects without complex firmware flashing.
• Three connection modes: Wired, Bluetooth and 2.4GHz modes allow easy switching between up to three devices and versatile use across desktops and mobile setups.
• Hot-swappable POM switches: Pre-lubed POM linear switches are installed for a smooth feel, and the hot-swap socket supports 3-pin and 5-pin switches for future customization.
• Long battery life: The built-in 4000mAh battery supports sustained wireless use for several days before recharging is needed.

Who It's For

The SK75 is best suited to gamers, streamers and professionals who prefer a compact 75% layout but still want robust build quality and a high-end typing sound. Users who appreciate customization will like the hot-swap PCB and VIA support for reprogramming keys and lighting.

People who need an ultra-light portable keyboard or who dislike a heavier, all-metal case should look elsewhere, as some users describe the all-aluminum construction as notably heavy. Also, if you require a numpad or a larger layout, a full-size board is a better match.
