“Lowering the actuation depth improved my reaction time in competitive games. Analog mode in racing titles feels surprisingly natural. The mouse glide is smooth.”
“I thought the macro didn't have infinite repetitions, but there are no helpful images anywhere on the internet. I still haven't found the answer.”

Nuphy Air75 V2 vs Keychron K2 HE: your questions
The Nuphy Air75 V2 is specifically marketed as a laptop partner, with a vendor-provided list of compatible MacBook, Surface, and other laptop models. Its low-profile design is intended to sit neatly over a laptop keyboard. The Keychron K2 HE also supports macOS and includes Mac keycaps, but its standard profile is not designed for the same over-the-keyboard use case.
No. The Keychron K2 HE is compatible exclusively with Gateron Double-Rail Magnetic Switches, as stated in its product description. It does not support standard mechanical switches or other magnetic switch types like the Gateron KS-20.
Yes. According to its technical specifications, the Nuphy Air75 V2 offers three adjustable angles: 3.5°, 6.5°, and 8.5°. This is achieved through its foldable feet system.
The main advantages are adjustable actuation points and advanced gaming features. You can set each key's actuation from 0.2mm to 3.8mm with 0.1mm sensitivity. This enables features like Rapid Trigger, Analog Mode for controller-like input, and Dynamic Keystrokes for multiple actions per key.
Both have a 4000mAh battery. The Nuphy Air75 V2 vendor page claims up to 220 hours with lights off. The Keychron K2 HE specifications list a wireless working time of up to 110 hours. Real-world results will vary based on usage, lighting, and connection mode.
It depends on the version. The Nuphy Air75 V2 offers optional shine-through nSA PC keycaps. For the Keychron K2 HE, the Standard Version has shine-through Cherry profile keycaps, while the Special Edition has non-shine-through OSA profile keycaps.
Yes. Both the Nuphy Air75 V2 and Keychron K2 HE support open-source QMK firmware and the VIA configurator for extensive key remapping, macro creation, and layer configuration without dedicated software.
The Nuphy Air75 V2 uses plate poron foam, an IXPE sheet on the PCB, and a silicone insert for the spacebar. The Keychron K2 HE uses a more extensive suite of foams: 3.5mm EVA acoustic foam, EPDM foam, a silicone acoustic pad, and PET film on the bottom case.
Yes, significantly. The Nuphy Air75 V2 weighs 598g. The Keychron K2 HE Special Edition weighs 965g, and the Standard Version weighs 980g, making it over 60% heavier.
The Keychron K2 HE is built for fast-paced gaming. Its 1000Hz polling rate, adjustable actuation points, Rapid Trigger, and features like Last Key Priority (LKP) are all designed to minimize latency and provide a competitive edge, as highlighted in its vendor description.
Neither keyboard includes a wrist rest in the standard box. However, both brands sell them separately. Nuphy offers Mono wrist rests in materials like beech, walnut, and acrylic. Keychron sells a silicone palm rest specifically compatible with the K2 series.
The Keychron K2 HE is available in a wide array of ISO layouts, including ISO-UK, ISO-DE, ISO-Nordic, ISO-CH (Swiss), ISO-ES, and ISO-FR, in addition to the standard ANSI layout. The Nuphy Air75 V2 is listed with an ANSI layout only.
