Design, Build Quality, and Portability
Chassis construction dictates how a keyboard sits on a workspace and whether it can reasonably accompany you outside the home. The Glorious GMMK Pro features a body CNC machined from solid aluminum, producing a heavy 3.3-pound base that measures 13.07 inches long, 5.31 inches wide, and 1.26 inches tall. The exterior undergoes an anodization process that yields high scratch resistance and a satin surface finish. Because of its weight and full-height frame, the GMMK Pro functions as an immovable desk anchor that never slides during intensive typing or gaming sessions. Glorious also built physical customization directly into the frame, allowing users to swap the top cover, interchange the pre-installed aluminum switch plate with brass or polycarbonate variants, and customize the integrated rotary dial.
The NuPhy Air75 V2 prioritizes a compact, streamlined footprint. It pairs an aluminum top frame with an innovative translucent bottom shell that exposes the internal engineering of the keyboard. Rather than creating a heavy monolithic block, NuPhy designed the Air75 V2 around low-profile mechanical architecture, keeping the total height and mass minimal for effortless transit. The keyboard slips into a messenger bag or rests directly over a laptop keyboard without burdening the user. When assessing the gmmk pro vs 3 comparison and other competing platforms, the Air75 V2 stands apart specifically through its travel-ready dimensions and hybrid materials.
The physical divergence between these two approaches represents a trade-off between absolute structural rigidity and daily portability. The GMMK Pro delivers a dense, reverberation-dampening enclosure that feels permanent and luxurious on a dedicated desk, but its 3.3-pound heft makes it entirely impractical to transport. The NuPhy Air75 V2 sacrifices full-metal mass for an agile build that transitions seamlessly between mobile cafes, conference rooms, and home workstations.

Users can freely install linear, tactile, or clicky switches without touching a soldering iron, utilizing the included switch puller and keycap puller. GMMK Pro switch compatibility gives enthusiasts the freedom to tailor bottom-out force, acoustic signature, and tactile feedback. Furthermore, the pre-installed aluminum plate can be swapped for a brass plate to increase firmness and sound pitch, or a polycarbonate plate to achieve a softer bottom-out feel.
The NuPhy Air75 V2 takes an integrated, ready-to-type approach. The keyboard comes fully assembled from the factory with low-profile Gateron Cowberry mechanical switches and durable PBT keycaps. PBT keycaps are resilient against finger oils, ensuring that key legends and textured surfaces resist shine and physical wear over extended usage cycles. Because the Air75 V2 utilizes a dedicated low-profile switch footprint, it does not support standard full-height MX mechanical switches or conventional high-profile custom keycap profiles. Instead, software-level customization takes center stage through native QMK/VIA firmware support. Users can reassign keys, define functional layers, and program complex keyboard behavior via an open-source web console. Comparing the gmmk pro vs akko 5075b plus shows how unusual this degree of deep firmware control is on pre-built wireless keyboards.
For builders who want an empty canvas to test specialty switch lubes, aftermarket plate acoustics, and custom artisan keycap profiles, the GMMK Pro provides total mechanical liberty. For typists who prefer skipping switch assembly while gaining open-source QMK/VIA key remapping on pre-installed PBT hardware, the Air75 V2 delivers complete functionality right out of the box.
