The NuPhy Air75 V3 is a compact (75%) wireless mechanical keyboard. It retains the low-profile design and wireless connectivity via Bluetooth or the included 2.4GHz USB receiver from its predecessor the NuPhy Air75 V2, but adds a new gasket-mount design that provides a softer typing experience. This new version also adds an optional knob located at the top-right of the keyboard, which controls volume by default. The launch of this keyboard also coincides with the launch of NuPhy's updated NuPhyIO 2.0 software experience. While it's mostly a UI update, this version adds an offline client for people who would want to change their settings without an internet connection. When it comes to performance, it maintains the 1000Hz polling rate and very good latency performance. The NuPhy Air75 V3 also has a hot-swappable design compatible with Gateron's low-profile 3.0 switches.
Our Verdict
Even if it isn't designed explicitly for this use, the NuPhy Air75 V3 is great for gaming. It delivers impressive latency performance and a 1000Hz polling rate. The build quality is also excellent. The keyboard feels solid, and the gasket-mount delivers a slightly bouncy and very comfortable gaming experience over long periods. The backlighting is very clear despite the lack of stock shine-through keycaps.

The NuPhy Air75 V3 is great for office use. Its low-profile design makes typing comfortable even without a wrist rest, since your wrists don't need to bend much to reach the keys. It's also very quiet to type on, thanks to layers of internal sound-dampening material, especially with the silent Blush Nano switches. The keyboard has excellent build quality and offers flexible connectivity, whether through its USB receiver or via Bluetooth with up to three devices at once. It's fully compatible with both Windows and macOS. However, the compact layout and flat nSA profile keycaps can feel a bit cramped at first, so it may take some time to adjust. People who prefer more tactile feedback may also feel that it feels a tad mushy, especially when paired with the Gateron Blush Nano switches we had on our unit.
Excellent build quality.
Very quiet and comfortable to type on over long periods.
Connects wirelessly via USB or via Bluetooth with up to three devices simultaneously.
Flat nSA keycap profile and compact form-factor may take a bit of getting used to initially.
As a compact and low-profile keyboard. the NuPhy Air75 V3 is easy to slip into a bag or carry around for use with tablets and mobile devices. However, it's slightly heavier and taller than its predecessor. It connects wirelessly via Bluetooth and can pair with up to three devices at the same time. The build quality is excellent, giving it a sturdy and reliable feel despite its portability. If you want to carry your keyboard around, NuPhy also gives you the option to buy a separate portfolio carrying case that doubles as a stand for your phone or tablet.
Excellent build quality.
Connects wirelessly via USB or via Bluetooth with up to three devices simultaneously.
On the heavier side compared to other keyboards designed for mobile devices.
The NuPhy Air75 V3 is well-suited for programming. Its low-profile design makes it both portable and comfortable to type on, even without a wrist rest. The build quality is excellent, and the internal sound-dampening layers help keep typing noise to a minimum. While it doesn't include dedicated macro keys, you can assign macros to any key through the companion software. It also features full RGB backlighting, though the stock keycaps aren't shine-through, which can make the legends harder to see in darker environments. You can, however, spec it with shine-through keycaps.

The NuPhy Air75 V3 is acceptable for home theater or entertainment use. Its compact size makes it convenient to use from the couch, and it can connect wirelessly to up to three devices at once over Bluetooth. However, it lacks useful features like a trackpad and dedicated media keys. Also, while it does include full RGB backlighting, the stock keycaps don't have shine-through legends, which makes the keys difficult to read in a dark room.

The NuPhy Air75 V3 delivers impressive raw performance that's well-suited for gaming in all genres at a casual or competitive level.

Differences Between Sizes And Variants
The NuPhy Air75 V3 is currently available only in a compact 75% layout. It comes in two color options: Nova White and Nebula Dark. It can be configured with one of three Gateron 3.0 Low Profile (Nano) switches: Red (linear), Brown (tactile), or Blush (silent linear). The default keycaps are double-shot PBT, which are not shine-through, though NuPhy offers a shine-through set for an additional cost. NuPhy has historically released additional 60% and 96% sizes in this lineup with each versioned iteration, and we expect to see those other sizes released at some point. If you come across such versions, let us know in the comments, and we'll update our review.
We bought and tested a Nebulza Dark colorway unit with Gateron Nano Blush switches. See our unit's label.
Here's a table summarizing the options available:
| Color | Size | Switches | Keycaps |
|---|---|---|---|
| Nova White | Compact (75%) | Gateron Nano Red (Linear) Gateron Nano Brown (Clicky) Gateron Nano Blush (Silent Linear) | Shine-through (extra cost), Non-shine-through PBT |
| Nebula Dark | Compact (75%) | Gateron Nano Red (Linear) Gateron Nano Brown (Clicky) Gateron Nano Blush (Silent Linear) | Shine-through (extra cost), Non-shine-through PBT |
Popular Keyboard Comparisons
The NuPhy Air75 V3 is a low-profile mechanical keyboard that succeeds the well-regarded NuPhy Air V2 series. Building on that foundation, the new Air75 V3 adds a multi-function rotary knob, a new gasket-mount design that enhances typing comfort with a more springy feel, and brighter backlighting.
Altogether, this wireless keyboard is a versatile choice for everyday browsing, productivity, and even casual or competitive gaming, and its compact form factor makes it easy to use on the go. It's a standout alternative to productivity boards that use laptop-style scissor switches, like the Logitech MX Keys S, and competes directly with low-profile mechanical options like the Keychron K3 Max and the Lofree Flow84. Although it shares many features with these competitors, the NuPhy stands out for its distinct aesthetic, its multi-function rotary knob, and its Gateron 3.0 Nano switches. These switches have a noticeably longer total travel distance, providing a typing feel closer to a standard mechanical keyboard while keeping the ergonomic and comfort benefits of a low-profile design, a major plus if you've found the typing experience on other low-profile boards too short and abrupt.

The NuPhy Air75 V3 and the Lofree Flow 2 are wireless, low-profile mechanical keyboards. The NuPhy has a plastic case but boasts full RGB backlighting, wider aftermarket switch compatibility, and slightly better gaming performance overall. The Lofree, on the other hand, is available in three different sizes and has somewhat better and more premium-feeling build quality with a solid aluminum case design. However, it only has white backlighting and uses relatively more limited VIA configuration software.
The NuPhy Air75 V3 replaces the NuPhy Air75 V2. It keeps a similar low-profile format, while being slightly taller and heavier. It also includes quite a few improvements. It features better latency performance, improved dampening, and clearer backlighting. It also includes an optional multifunctional knob that fits on the top right of the keyboard and a gasket-mount design that offers a more springy typing experience. The V3 is also built on the newer Gateron low-profile 3.0 standard, which supports switches with up to 3.5 mm of travel.
The Keychron K5 Max and the NuPhy Air75 V3 are wireless mechanical keyboards with low-profile designs. Overall, these two keyboards are very comparable in terms of features and are very well-built. The NuPhy, however, includes an optional knob and clearer backlighting and should last longer on a single charge. Its newer Gateron Low-Profile 3.0 switches also provide a full 3.5 mm of travel, which is longer than the Keychron's maximum of 3.0 mm.
The NuPhy Air75 V3 and the NuPhy Air75 HE are low-profile keyboards with a similar look and form factor, but they are designed for different purposes. The Air75 V3 uses mechanical switches, making it a versatile option suitable for both gaming and productivity. The Air75 HE, on the other hand, is better suited for gaming and features Hall effect switches with adjustable actuation, Rapid Trigger and SOCD support, and a maximum polling rate of 8000 Hz.
