NuPhy Air75 V3 Review (2026): Slim, Quiet, Long-Lasting

This NuPhy Air75 V3 review looks at a low-profile 75% wireless keyboard built for people who want a quiet, comfortable typing feel in a slim 13.2mm body. It's based on NuPhy's published specifications and what independent expert reviews report, not on hands-on testing by us.

The Air75 V3 sits in the mid-range part of the market. It targets Mac and Windows users who want a slim, quiet wireless keyboard. Below we go through the design, the connectivity and battery, the typing experience, and where reviewers say it falls short.

NuPhy Air75 V3 Review: Design and Build

The Air75 V3 uses an ANSI 75% layout with 84 keys. That keeps the arrow keys and a function row but drops the number pad, so it takes up little desk space. The body measures 318.9 mm x 128.9 mm x 13.2 mm, which makes for a slim body, and it weighs 724 grams (1.6 pound).

The top case is aluminum and the bottom case is ABS. Reviewers praise the aluminum top as giving the keyboard a premium, sturdy feel. The plate is PC, and the keycaps are double-shot PBT.

The gasket mount is the headline of the design. In a gasket-mounted keyboard the plate and switches are held on soft mounting points rather than screwed rigidly to the case. The aim is a softer, more cushioned typing feel and a quieter sound. Reviewers consistently describe the typing feel as soft, quiet and comfortable, with a refined sound.

A 3-stage kickstand sets the typing angle at 4°/8°/10°.

Switches and Typing Feel

The keyboard uses low-profile Gateron Nano 3.0 switches in Red, Brown or silent Blush. The Blush is the silent option. All three are hot-swappable, so you can pull the switches out and fit compatible ones without soldering.

The lineup of three options is also one of the common criticisms. Reviewers note there is no clicky choice. If you want an audible click on every press, this keyboard is not designed around that. If you want a quiet board, the lineup fits well, especially with the silent Blush option and the gasket mount.

Connectivity and Battery Life

The Air75 V3 is tri-mode: a 2.4GHz dongle, Bluetooth 5.0, or wired USB-C. Each suits a different situation:

• 2.4GHz uses the included dongle, with a 1000Hz polling rate.
• Bluetooth 5.0 connects without the dongle, but polling drops to 125Hz.
• Wired USB-C also gives 1000Hz polling and works as a fallback when you don't want to rely on the battery.

Polling is 1000Hz over 2.4GHz and wired, and 125Hz over Bluetooth.

Battery is a strong point on paper. The 4000mAh battery is rated for up to 1200 hours with RGB off, and 60~100 hours with RGB on. Both are lab-test figures from the manufacturer, so real-world results will depend on your lighting settings and usage. Reviewers praise the long battery life with RGB off.

Features That Matter Day to Day

The Air75 V3 has a dedicated Mac and Windows layout switch, along with shortcut keys. That suits anyone who moves between Mac and Windows machines.

There is also a removable, programmable knob. NuPhy includes both high- and low-profile modules in the box, so you can choose the look and height you prefer. A common criticism is that the knob can feel wobbly, especially the high-profile module. If you plan to use the knob heavily, that's worth weighing.

Backlighting is a north-facing RGB LED with 20 modes. Reviewers point out that the north-facing RGB backlighting is not true per-key lighting. It still provides lighting effects, but it isn't the right board if you want precise, individually customised colours.

Software and Customisation

Remapping, macros and lighting are handled through NuPhy IO, a web-based tool. A web-based tool means nothing to install, which is convenient. The drawback is that it is proprietary, and the keyboard has no VIA or QMK support. If you rely on those ecosystems for keymaps and layers, this is a real limitation. If you just want to remap a few keys and set up some macros, NuPhy IO should cover it.

What Experts Like and Criticise

The Air75 V3 averages 8.6/10 across 3 expert reviews. Tom's Guide scores it 4.5/5, Crafting Worlds gives it 8.8/10, and techboys.de rates it 8.1/10.

What reviewers praise:

• The soft, quiet, comfortable typing feel that the gasket mount produces.
• The aluminum top case and the sturdy, premium build.
• The long battery life with RGB off.
• The three connection modes, with 1000Hz polling over 2.4GHz and wired.
• The combination of hot-swappable low-profile switches, a slim 13.2mm body and a kickstand.

Common criticisms:

• The knob can feel wobbly, especially the high-profile module.
• Switch choices are limited to Red, Brown and silent Blush.
• The software is proprietary, with no VIA/QMK support.
• The backlighting is not true per-key RGB.

These criticisms could matter depending on how much you value customisation.

Who Should Buy the Air75 V3

The Air75 V3 makes sense if you:

• want a slim, quiet wireless mechanical keyboard;
• switch between Mac and Windows and want the layout handled for you;
• value a quiet typing sound;
• like the idea of long battery life and the flexibility of 2.4GHz, Bluetooth or a cable;
• want hot-swappable switches so you can adjust the feel later.

Who Should Skip It

Look elsewhere if you:

• want clicky switches, since the options here are Red, Brown and silent Blush;
• depend on VIA or QMK for deep remapping;
• want true per-key RGB lighting;
• plan to use the knob constantly and want it to feel rock solid;
• need a number pad, as this is a 75% layout.

How It Fits in Its Category

Its pitch is a quiet, comfortable, premium-feeling board with tri-mode connectivity.

Verdict

The NuPhy Air75 V3 is an easy keyboard to recommend to people who type a lot, work across Mac and Windows, and prefer a quiet, slim board. The gasket mount, aluminum top case, tri-mode connectivity and long battery life are all well supported by the specifications and by reviewer feedback. Its weak points are specific rather than fundamental: a wobbly knob, a small switch selection, closed software and simple lighting. If those don't affect how you'd use it, the Air75 V3 is a strong choice in the mid-range part of the wireless keyboard market.
