Our Verdict
NuPhy Air75
Keychron S Series
The NuPhy Air75 and the Keychron S Series are both low-profile mechanical keyboards with hot-swappable PCBs compatible with Gateron Low Profile mechanical switches. These two keyboards are very similar but have a couple of standout differences. The NuPhy is a wireless model and can pair with up to three devices simultaneously via Bluetooth. Also, the body of the keyboard is made of metal on top and plastic on the bottom. On the other hand, the Keychron S Series keyboards are wired only, and their bodies are made entirely of aluminum.
