NuPhy Air75 HE

Manufacturer: NuPhy

The NuPhy Air75 HE is a compact 75% mechanical keyboard built for gaming, combining a low-profile form factor with a construction that blends plastic and aluminum materials. It connects via wired USB and ships in either black or white colorways, with RGB backlighting directed south-facing across its keycaps. The case sits on adjustable feet and uses a top-mount design, while the detachable cable adds a degree of convenience for transport or cable management.

At the core of the Air75 HE are Low-Profile Magnetic Jade Pro Hall effect switches, which are linear in feel and offer an adjustable actuation range spanning from 0.1 mm to 3.3 mm, with a total travel distance of 3.5 mm and an actuation force of 40 g. The keyboard supports rapid trigger, dual actuation, analog input, adjustable actuation, and full NKRO, and reaches a polling rate of 8000 Hz. Keycaps are PBT with a DSA profile in a standard ANSI layout, and the board weighs 702 g with dimensions of 316.4 × 132.5 × 18.4 mm. The warranty period covers one year from purchase.

Pros
  • The adjustable actuation range of 0.1 mm to 3.3 mm gives users precise control over switch sensitivity, which is particularly useful in fast-paced gaming scenarios
  • Rapid trigger, dual actuation, and analog input support make the most of the Hall effect switch technology for competitive use
  • An 8000 Hz polling rate ensures very frequent position reporting to the host system
  • The detachable cable adds convenience when transporting the keyboard or managing desk cable routing
  • RGB backlighting with south-facing LEDs and a standard DSA keycap profile provides good compatibility with aftermarket PBT keycap sets
  • The compact 75% layout retains function row and arrow keys while keeping the overall footprint modest at 316.4 x 132.5 mm
Cons
  • Switches are not hot-swappable, so replacing them requires desoldering
  • No support for QMK, ZMK, or VIA means users are limited to the manufacturer's own software for customization
  • Media controls are only accessible through the Fn layer rather than dedicated keys, which can be less convenient during quick adjustments
  • No wrist rest is included, which may affect comfort during extended typing sessions
  • The keyboard is wired-only with no wireless option, restricting flexibility in certain desk setups
  • At 702 g, the board carries noticeable weight for a compact 75% form factor
Who is this for?

The Air75 HE is well-suited to competitive and enthusiast gamers who want precise control over their input, thanks to its adjustable actuation range, rapid trigger, and dual actuation capabilities built on Hall effect switch technology. The compact 75% layout makes it a reasonable fit for users with limited desk space who still want function row and arrow key access. Those who appreciate a low-profile typing experience with RGB lighting and a clean aesthetic in either black or white will also find this board a natural match.

Who is this NOT for?

Users who prefer open-source firmware customization will find the Air75 HE limiting, as it lacks support for QMK, ZMK, and VIA, leaving them dependent on the manufacturer's own software. Those who frequently swap switches will also face friction, since the board does not support hot-swap, making any switch change a soldering job. Additionally, users who work primarily on Mac systems or who need a wireless connection will find the board a poor fit, as it is neither designed for Mac nor capable of connecting without a physical cable.

The Air75 HE is equipped with Low-Profile Magnetic Jade Pro Hall effect switches, which deliver a linear feel with an actuation force of 40 g and a total travel distance of 3.5 mm. The actuation point is adjustable across a range of 0.1 mm to 3.3 mm, allowing for a high degree of sensitivity tuning. These switches are not hot-swappable, meaning they cannot be replaced without desoldering.

The Air75 HE supports a strong set of gaming-oriented features, including rapid trigger, dual actuation, adjustable actuation, and analog input, all of which take advantage of its Hall effect switch technology. Full N-key rollover (NKRO) is also present, ensuring every simultaneous keypress is registered accurately. On the other hand, the board does not include USB passthrough, an onboard display, or support for QMK, ZMK, or VIA, which limits options for open-source firmware customization.

Keys & layout:

Keyboard layout ANSI (United States)
Keycap type PBT
Keycap profile DSA
uses a standard key layout ✓
Media keys Via Fn key
has a rotary dial ✕

The Air75 HE uses an ANSI (United States) layout with a standard key arrangement, making it compatible with a wide range of aftermarket keycap sets. The keycaps themselves are made from PBT material and feature a DSA profile, which gives each key a uniform, low, spherical top. Media controls are accessible via the Fn key rather than dedicated keys, and there is no rotary dial on the board.

Final Verdict

The NuPhy Air75 HE is a focused gaming keyboard that delivers where it counts for competitive users — its Hall effect switch technology with adjustable actuation, rapid trigger, and 8000 Hz polling rate forms a technically capable core that few keyboards in its form factor can match. The compact 75% layout, low-profile build, and detachable cable keep the design practical, while the aluminum plate and RGB lighting give it a solid physical presence. Where it pulls back is on flexibility: the absence of hot-swap support, wireless connectivity, and open-source firmware compatibility means users outside the wired competitive gaming niche may find it restrictive. For those it is built for, however, the Air75 HE represents a well-specified, purpose-driven board that prioritizes input precision above all else.
