What will you mostly use it for?
The J2 HE takes the gaming comparison for buyers who prioritize wired 8000 Hz polling and magnetic switches. The V3 Max is the more versatile pick across office work, programming, travel, modding, and content creation, thanks to its wireless options, broader layout selection, and MX switch support. These advantages come with a larger 80% footprint and a lower listed polling rate than the J2 HE. Neither has a numpad.
Pick the Keychron J2 HE
- The J2 HE is wired and lists an 8000 Hz polling rate, compared with the V3 Max's 1000 Hz in wired and 2.4 GHz modes.
- The J2 HE uses Hall Effect magnetic switches, while the V3 Max uses Gateron Jupiter mechanical switches in its assembled version.

“Worked perfectly, best keyboard I've ever owned. For one hour. After that all RGB turned off, and the main function of the keyboard (Typing), no longer works. I can't type with it, the web launcher doesn't detect it either, just don't waste your money.”

“Stopped working in wired mode after a couple months. 2.4 connectivity spotty. I regret buying this keyboard”
