NUPHY AIR75 V2 - CUSTOMIZABLE WIRELESS MECHANICAL KEYBOARD Those who have used mechanical keyboards understand that they not only optimize work speed but also enhance the typing experience during long hours. This is especially true for jobs that require frequent keyboard interaction, such as content writers, designers, gamers, etc. However, limitations like bulky designs, difficulty in portability, and loud typing noises have made many hesitant to dive into the exciting world of mechanical keyboards. This is why low-profile mechanical keyboards are becoming increasingly popular, as they address these drawbacks while retaining the inherent advantages of traditional mechanical keyboards. The NuPhy Air75 V2 is an improved low-profile mechanical keyboard with a 75% layout and ultra-slim design. Its keycaps are spherically designed and made of PBT material. Compatible with both macOS and Windows, it supports wireless connectivity with up to four devices simultaneously with minimal latency. If you need a versatile keyboard that optimizes the mechanical keyboard experience, check out the NuPhy Air75 V2. Appearance and Design Overall Overall, the NuPhy Air75 V2 embodies the youthful, dynamic character that NuPhy has built, clearly expressed through its vibrant keycap color schemes. However, in its mid-range price segment, NuPhy still ensures a luxurious and modern look by incorporating a premium aluminum frame. The aluminum frame is just high enough to cover the switch stems while maintaining an ultra-thin overall keyboard profile. The bottom panel is made of transparent ABS plastic, allowing a clear view of the hidden keys underneath. NuPhy scores 10 points for finesse with a mirror-polished metal information plate, which enhances the aesthetic of the plastic bottom while cleverly concealing the battery compartment. The back panel is the most intricately upgraded design feature from V1 to V2, with enhanced PBT plastic transparency to clearly reveal the internal structure. Improved materials for the keyboard plate An advanced aluminum alloy stamping method was used to achieve a seamless unibody aluminum design. This method allows NuPhy to completely hide the mechanical switches under the aluminum frame and keycaps while maintaining a simple structure. It also significantly reduces the product’s weight compared to traditional CNC machining. The aluminum frame in the Air75 V2 has been upgraded with precision laser processing and anodization on the top surface. Acoustic engineering is increasingly seen as a critical factor in keyboard sound quality. NuPhy claims this technique was previously only applied to the Air96 model. For the Air75 V2, NuPhy continued using it with IXPE PCB acoustic tuning, successfully achieving deeper and clearer switch sounds. Additionally, NuPhy applied silicone sound-shaping technology, derived from the design of their Ghostbar spacebar, for a more flexible typing feel and enhanced “thock” sound from the switches. Double-shot PBT Keycaps The ultra-thin PBT keycaps feature a 4.6mm concave design that follows the natural curve of fingertips. This ergonomic design makes typing easier and more comfortable during extended use. Using PBT material, the NuPhy Air75 ensures sharp color clarity and resistance to oil buildup over time, unlike ABS plastic. >> Buy now: NuPhy Air75 Twilight Keycap Set Perfect Compatibility Design for Mac and Windows The surrounding frame uses aluminum to perfectly match the color scheme of Macs.

The Air75 is the perfect mechanical keyboard for multitasking users. The lower half’s plastic design mitigates the drawbacks of Bluetooth and wireless connections between the keyboard and devices. Additionally, the NuPhy Air75 comes with a USB-C cable. With these three connectivity modes, NuPhy can meet any usage need. 2.4G Connectivity Battery Capacity Equipped with a 4000mAh battery, an upgrade from V1, it provides up to 220 hours of battery life without backlighting, supporting over two weeks of productive work. Easy Customization for Typing Preferences One feature that mechanical keyboard enthusiasts care about is whether switches can be customized. Great news: you can easily replace or upgrade switches on the Air75 V2 without soldering, thanks to its hot-swappable feature. NuPhy also provides four replacement switches for the V2 version (Aloe Linear, Cowberry Linear, Wisteria Tactile, Moss Tactile) and a keycap puller included in the package. This is a great deal, allowing you to experience different typing feels before investing in a full switch set or quickly replacing a faulty switch. RGB Backlit and Sidelit LED System Sidelit NuPhy equips two RGB LED strips on both sides of the aluminum frame, inspired by the MacBook’s battery notification system. The left LED strip indicates Caps Lock status, while the right strip shows battery status. Backlit The keyboard features an RGB Backlight system underneath. The lighting is bright enough without being overly glaring, avoiding a cheap appearance. You can switch between 40 display modes using hotkeys or download NuPhy’s app to freely customize brightness, flashing, and color tones to your preference. DIFFERENTIATING SWITCH TYPES AND FINDING THE RIGHT CHOICE FOR YOU Three Upgraded Gateron Switch 2.0 Types from V1 Technical Specifications: Four Switch Types for the Air75 V2 Technical Specifications: NuPhy’s low-profile switches have been warmly received since the Air96’s release. From there, NuPhy experimented with various formulas to develop switches with longer travel distances, precise typing, and pre-lubed designs. This resulted in a wider variety of switch “flavors” for the Air75 V2, developed based on the Gateron Baby Kangaroo line. Similarities Among Switch Types The NuPhy Air75 V2 uses Gateron Low-profile switches, ultra-thin mechanical switches designed specifically for low-profile keyboards. These switches have shorter travel distances and faster actuation than standard switches, providing a fast, smooth typing experience. This is why Gateron Low-profile switches are considered among the best for gaming. Short pre-travel distance of approximately 1.3 - 2.1mm within a total travel of 3.0 - 3.4mm. The Cowberry switch has an even shorter pre-travel of 0.9 - 1.5mm. Lubed switches provide a smoother typing experience, reducing hand fatigue during extended typing. Lubrication also minimizes rattling and friction, extending switch lifespan. The stem (the part that moves up and down inside the switch) is made of POM, which maximizes smoothness and reduces friction. The sound profile of the POM stem, combined with a PA66 (nylon commonly used in high-quality switches) bottom housing, produces a deeper sound, with a softer bottom-out feel compared to switches made of other materials. The top housing (the part that stops the stem at the end of its travel) is made of PC, providing a crisp, clear snap-back sound. Sound Test Choosing Based on Your Needs 1. Clicky Group: Blue Switch 2.0 Not recommended for those who dislike the noise of mechanical keyboards. Suitable for gaming and those who enjoy the tactile “clicky” sound when typing. Characteristics: Fast response, relatively heavy keypress, and distinct tactile feedback. 2. Linear Group: Red 2.0 / Aloe / Cowberry Ideal for those who prefer mechanical keyboards but dislike noise. This group ensures a quiet, smooth sound, with Cowberry having the softest and deepest sound profile. For gaming needs requiring fast response, good keypress, and smooth actuation without sticking, Red Switch and Cowberry Switch perform well. However, if you need additional force feedback to register keypresses, Cowberry gets an extra point. For office use where noise might disturb others, any of these three switches are great choices. All three allow comfortable typing and reduce hand fatigue during long sessions. For newcomers to mechanical keyboards unsure about which to choose, Aloe Switch is a safe option. The high sensitivity of Red 2.0 and Cowberry, combined with their light actuation force, may require some adjustment when transitioning from rubber dome keyboards to mechanical ones. 3. Tactile Group: Brown 2.0 / Moss / Wisteria A balance of actuation force and sound. This group is less noisy than Blue 2.0 while inheriting the smooth, fast response of the Linear group. The sound is deep and pleasant. This group is suitable for both office and gaming needs. The sound profile, ranked from least to most deep, is Brown - Moss - Wisteria. Brown 2.0 has a slight clicky undertone when listened to closely.
