What will you mostly use it for?
The J1’s strongest fit is a compact setup that benefits from 2.4 GHz wireless and sound dampening. The K1 Pro stands out for buyers who need an ISO layout, dedicated multimedia keys, or its aluminum frame. Both list a 1000 Hz polling rate, so the gaming choice depends more on the preferred connection and layout. For programming and customization, the K1 Pro’s vendor-described keymap options and switch details give it a slight edge.
It's a tie
- Both list a 1000 Hz polling rate for wired use.
- The J1 adds a 2.4 GHz connection, while the K1 Pro vendor description specifies 1000 Hz in wired mode and Bluetooth 5.1.

“I like everything about this keyboard: the keys, their profile, the typing sound of the banana switch, the shape of the keyboard itself, and its size. There are no battery issues either; it holds a charge surprisingly long, and I don't remember the last time…”
Keychron K1 Pro

“I realy like this keyboard. I feel is harder to make typos compared to the K3 v2. I decided to go with the K1 Pro instead of the K3 Pro and it's going to to take time to adjust to the new layout, but the feeling and shape of the keys is definitely better.”

Keychron J1 vs K1 Pro: your questions
The J1 adds 2.4 GHz wireless and sound dampening in a 75% layout. The K1 Pro offers ISO layout variants, multimedia keys, and an aluminum frame.
Yes. The J1 lists 2.4 GHz, Bluetooth, and wired connectivity, and Keychron describes all three connection options.
Yes. Its listed layouts include ISO, ISO-DE, ISO-Nordic, ISO-UK, ISO-FR, and other variants. The J1 is listed as ANSI only.
The K1 Pro lists multimedia keys as an extra feature. The J1’s listed extra features do not include them.
No. Both boards are specified for low-profile switches and keycaps, and their compatibility notes say standard MX keycaps will not fit.
Both boards have north-facing LEDs, and their compatibility notes warn that Cherry-profile keycaps can hit the switch housing. Check keycap and switch clearance before buying a set.
Both list hot-swappability, but the vendor descriptions specify hot-swappable versions. The K1 Pro vendor says its hot-swap option works with low-profile Gateron mechanical switches.
The J1 is listed as a 75% board measuring 23 x 327 x 144 mm. The K1 Pro is an 80% board measuring 8 x 346 x 119 mm, so the J1 is narrower while the K1 Pro is shallower by the listed dimensions.
The K1 Pro is listed at 580 g, while the J1 is listed at 661 g. That makes the K1 Pro lighter by the stated weights.
Both list QMK support. The K1 Pro vendor also describes key remapping, macros, shortcuts, and customization through Keychron Launcher.
Both list Mac/Win support. Keychron says the K1 Pro includes keycaps for macOS and Windows and can use different keymaps for each.
Neither has a numpad, according to their compatibility notes. The J1 is a 75% board and the K1 Pro is an 80% layout.
