Nuphy Air75 V2 vs Gem80Low-Profile vs Custom Build

The Nuphy Gem80 is sold primarily as a barebones kit. According to the vendor description, it comes with the PCB, sound mods, and pre-lubed stabilizers assembled, but you must separately purchase and install your own switches and keycaps to complete the keyboard.

Yes, the Nuphy Air75 V2 lists compatibility with macOS, Windows, and Linux. The vendor page specifically mentions implemented shortcuts for macOS features like Spotlight, Dictation, and Launchpad via QMK. It also includes Mac-specific replacement keycaps in the box.

Both keyboards offer a 1000Hz polling rate in their 2.4GHz wireless mode, which is suitable for gaming. The Air75 V2 has low-profile switches like the Cowberry optimized for fast actuation. The Gem80 provides the same wireless performance in a heavier, more stable chassis. The choice comes down to your preference for low-profile versus standard-profile key switches.

The Gem80 is available in two variants: a wired-only version and a tri-mode version. The tri-mode version, as per its tech specs, supports Bluetooth 5.0, 2.4GHz wireless, and wired USB-C connectivity. You must select the tri-mode option at purchase.

The Air75 V2 uses low-profile switches with a 3.0-3.2mm total travel, resulting in a short, snappy keypress. The Gem80 uses standard-profile switches and a gasket mount design, which typically provides a bouncier, more cushioned typing feel. The Gem80 also allows you to change the mounting style and plate material to fine-tune this feel.

The Air75 V2 comes with double-shot PBT keycaps. The Gem80 barebones kit does not include keycaps, but Nuphy sells themed PBT keycap sets separately. The vendor description for the Gem80 also mentions optional ABS keycaps in its accessory list.

Both have a 4000mAh battery. Lab test results from the vendor pages show the Air75 V2 lasting up to 220 hours with lights off, while the Gem80 tri-mode is listed for up to 330 hours with lights off. Actual battery life will vary with usage, lighting, and connection mode.

Yes, both the Air75 V2 and Gem80 are hot-swappable, allowing you to change MX-style switches without soldering. The Air75 V2 is compatible with low-profile KS-33 switches, while the Gem80 supports standard 3-pin or 5-pin MX-style switches.

The Air75 V2 comes as a complete package. According to the vendor, the box includes the keyboard, a USB-C cable, a 2.4G receiver, 7 extra keycaps, 4 extra switches, a keycap/switch puller, a sticker set, and a quick guide.

Omni-mount on the Gem80 refers to its ability to be configured in different mounting styles. Using the included gasket and mount kit, you can set up the keyboard as a gasket mount, top mount, or bottom mount, each offering a different balance of flex, sound, and typing feel.

The Gem80 specifically lists south-facing RGB LEDs in its specifications and vendor description. The Air75 V2's specifications confirm RGB backlighting but do not specify the LED orientation. South-facing LEDs are beneficial for preventing interference with Cherry-profile keycaps.
