NuPhy Air75 V3 specifications and in-depth review

NuPhy Air75 V3

Manufacturer: NuPhy

The NuPhy Air75 V3 is a 75% layout mechanical keyboard that combines a low-profile form factor with versatile wireless and wired connectivity. Built around a gasket mount construction, it offers a degree of flex and vibration dampening that distinguishes it from simpler tray or top-mount designs. The case is available in black or white and uses a combination of plastic and aluminum materials, with an aluminum plate underneath the keycaps.

Connectivity covers Bluetooth 5.0, 2.4GHz wireless, and USB, with a 1000 Hz polling rate over wired mode and a rated battery life of 1200 hours. The keyboard ships with NuPhy Red Nano Linear switches featuring a 2 mm actuation point, 45 g actuation force, and 3.5 mm total travel, and the switches are hot-swappable. Keycaps are double-shot PBT with an OEM profile, the layout follows the standard ANSI arrangement, and RGB backlighting is north-facing. N-key rollover is supported, while features such as QMK, VIA, rapid trigger, and analog input are not included.

Pros
  • Hot-swappable switches allow for easy switch replacement without soldering
  • Triple connectivity via Bluetooth 5.0, 2.4GHz wireless, and USB offers flexible usage across different setups
  • Gasket mount construction provides a degree of flex that reduces typing harshness
  • Rated battery life of 1200 hours makes wireless use practical over extended periods
  • N-key rollover ensures every simultaneous keypress is accurately registered
  • The detachable cable adds convenience for transport and cable replacement
Cons
  • No support for QMK, ZMK, or VIA, limiting firmware-level customization options
  • Media controls are only accessible via the Fn key, with no dedicated media keys
  • Does not include rapid trigger or adjustable actuation, which limits input precision options for gaming
  • No wrist rest is included, requiring a separate purchase for ergonomic support
  • The keyboard is not designed for Mac, so Mac users may need to remap certain keys manually
Who is this for?

The Air75 V3 is well-suited to users who want a compact, low-profile keyboard that transitions comfortably between desk setups and mobile use, thanks to its 75% layout, slim 13.2 mm profile, and tri-mode connectivity. The 1200-hour battery life and wireless flexibility make it a practical choice for those who frequently switch between devices or work in environments where cable management is a concern. Users who like to experiment with different switches will also appreciate the hot-swappable socket design, which allows switch changes without any soldering.

Who is this NOT for?

Users who rely heavily on firmware customization through QMK or VIA will find this keyboard limiting, as none of those platforms are supported. It is also a poor fit for competitive or precision-focused gamers who depend on rapid trigger or adjustable actuation point functionality, as neither feature is available. Additionally, users who prefer a full-size or tenkeyless layout with dedicated media keys and a wrist rest included out of the box will find the 75% layout and Fn-layer-only media access less convenient for their workflow.
