Choose the NuPhy Air75 V2 if low-profile mechanical switches and a 598g build matter most; its low-profile design and switch options are features the Keychron does not provide. Choose the Keychron K2 HE for Hall Effect controls, adjustable actuation and Rapid Trigger, which the NuPhy does not list. Check the compatibility limits before buying replacement switches or keycaps for either board.

What will you mostly use it for?
The Keychron has the clearest edge for gaming and magnetic-switch customization, with adjustable actuation, Rapid Trigger and layered key actions. The NuPhy is the more portable option by listed weight and is the only low-profile board here. Office, programming and content creation depend more on preference: both offer remapping and multiple connection modes, while the Keychron adds magnetic controls and broader listed layouts. Component swaps require attention to each board's distinct switch and keycap limitations.
Pick the Keychron K2 HE
- Hall Effect switches support adjustable actuation from 0.2 to 3.8 mm and Dynamic Rapid Trigger.
- Dynamic Keystrokes can assign up to four actions to a key, and Analog Mode provides variable input.
- The NuPhy offers 1000 Hz polling over 2.4 GHz, but its listing does not describe these Hall Effect controls.

Nuphy Air75 V2 vs Keychron K2 HE: your questions
The Keychron K2 HE is the more feature-focused gaming choice, with Hall Effect switches, adjustable actuation and Dynamic Rapid Trigger. The NuPhy Air75 V2 has 1000 Hz polling over 2.4 GHz, but its listed features do not include those magnetic-switch controls.
Yes. The K2 HE lists Dynamic Rapid Trigger, which can activate or reset keys based on how far they travel. Its Hall Effect switches also support adjustable actuation.
No. The Air75 V2 requires low-profile switches and keycaps, and standard MX keycaps will not fit. Its product description identifies the switches as low-profile mechanical.
No. The K2 HE is compatible with Gateron double-rail magnetic switches, and standard MX switches will not fit. Keychron also says it does not support other magnetic switch types such as Gateron Magnetic Jade or KS-20.
The NuPhy Air75 V2 is listed at 598g. The Keychron is approximately 965g for the Special Edition or 980g for the Standard Version, so the NuPhy is the lighter choice based on the listed weights.
Yes. Both list Bluetooth and 2.4 GHz wireless connections, as well as wired USB-C. The product descriptions specify 1000 Hz polling in 2.4 GHz mode for both.
No. The Air75 V2 is listed as ANSI, and its compatibility notes say ISO variants are not offered. The K2 HE lists several ISO options, including UK, DE, ES, FR, CH and Nordic.
The K2 HE has north-facing LEDs, and its compatibility notes warn that Cherry-profile keycaps can hit the switch housing. Check the specific keycap profile and clearance before buying a replacement set.
Both list QMK and VIA support, hot-swappable switches and a 75% layout. The K2 HE additionally supports key remapping, macros and actuation adjustment through Keychron Launcher, which the vendor says to use with the keyboard connected in wired mode.
The Air75 V2 listing describes low-profile mechanical linear and tactile switches, but does not list adjustable actuation. The K2 HE explicitly supports adjustable actuation points from 0.2 to 3.8 mm.
The Keychron K2 HE lists ANSI, JIS and multiple ISO layouts, including UK, DE, ES, FR, CH and Nordic. The NuPhy Air75 V2 is listed as ANSI only.
NuPhy describes plate Poron, PCB IXPE and silicone sound shaping for the Air75 V2 spacebar. Keychron lists 3.5 mm EVA acoustic foam, EPDM foam and a silicone pad inside the K2 HE.
