Overview

The NuPhy Air75 V2 is the low-profile mechanical keyboard that finally makes the genre viable for both typing and gaming. It improves on the original Air75 in nearly every way - better switches, wireless that actually works, and a gasket mount that makes it feel more substantial than its 582g weight suggests. At $129, it undercuts the Logitech MX Mechanical Mini while offering hot-swappable switches and superior build quality.

Design & Build

NuPhy has refined the formula rather than rewritten it. The 75% layout retains the function row and arrow keys in a footprint barely larger than a 13-inch laptop keyboard. The new plastic case is subtly textured and more rigid than the V1’s, with less flex in the center. The gasket mount is the real upgrade - it gives the typing feel a soft, bouncy quality that low-profile boards rarely achieve, absorbing bottom-out impact without feeling mushy. The two-stage kickstand offers 9° and 18° typing angles, and the PBT keycaps are thick and textured with crisper legends than the original’s ABS set. The white backlight on the Night Breeze switch variant is clean and uniform, with no bleed between keys.

Performance

The Night Breeze switches are NuPhy’s new proprietary low-profile linear, factory-lubed with a 55g actuation force. They’re smoother than Gateron 2.0 Low-Profile Reds and quieter than the original Air75’s browns - the sound profile is a pleasant, muted clack rather than a hollow ping. Typing on them for extended sessions is fatigue-free, and the 3.2mm total travel feels more natural than the ultrashort throws of scissor-switch laptop keyboards. Gaming performance is excellent; the 2.4GHz dongle delivers sub-3ms latency that’s indistinguishable from a wired connection. Bluetooth 5.0 supports three-device pairing with instant switching via the Fn+1/2/3 shortcuts - useful for hopping between a desktop, tablet, and phone.

Features

Hot-swappable switch sockets are the headline feature at this price tier - you can swap in any Gateron low-profile switch without soldering, which is a rarity outside the enthusiast market. The 4,000 mAh battery lasted me three full weeks of daily use with backlighting on at medium brightness, and charging over USB-C takes about two hours. The included keycap puller and switch puller are genuinely usable (not the flimsy wire tools most brands bundle). NuPhy’s QMK/VIA web configurator lets you remap any key and create multiple layers, though the process requires you to manually flash firmware in wired mode - it works but lacks the polish of Keychron’s VIA implementation.

Pros

• Excellent typing feel with gasket mount
• Hot-swappable low-profile switches
• Reliable triple-mode wireless
• Great value at $129

Cons

• Plastic case lacks the premium heft of metal boards
• VIA configuration process is clunky
• No per-key RGB (white backlight only)
• Stabilizers have slight rattle on the spacebar

Verdict

The NuPhy Air75 V2 is the low-profile keyboard to buy if you want mechanical feel without the desk-eating footprint of a full-height board. The typing experience is shockingly good for a $129 keyboard, and the hot-swappable switches mean you can tailor the feel to your preferences. It’s not as premium as the Keychron Q5 Pro, but it’s also half the price and a third of the height.
