What will you mostly use it for?
The K4 HE is the more suitable pick when a numpad, ISO layout, or lower listed weight matters. The P3 HE makes more sense for gaming-focused buyers who prefer a gasket-mounted 80% board and the vendor-described screwless top-case design. Programming is a close match because both support QMK, VIA, and web-app remapping. For content creation, the K4 HE’s numpad is the clearest differentiator, while both offer wireless and wired connections.
Pick the Keychron Lemokey P3 HE
- Both have Hall Effect magnetic switches, Rapid Trigger, and a 1000 Hz polling rate.
- The P3 HE adds a gasket mount, and its vendor description specifies adjustable actuation from 0.01 to 3.35 mm.

“So far it have met my expectations for the use i wanted it for, had a small hic up the first day i started ysing it but got easily resolved with the provided user manual”
“The keyboard is smooth to the touch, and has the nice feel. For me, it's almost an ideal keyboard but the one thing that gets me and it's a hard issue is that when connected, it takes away input from my controller when I game, especially for live service…”

“Typing feel incredible. My first HE/magnetic switch keyboard and I am completely satisfied. The board itself is heavy and solid. Love the LED lighting. One week in and I'm hooked.”
