The Q series used to be wired only. The new Q Pro series are wireless.

I use a Q6 at home and love it. I bought a k12 for work, and while its great its much noisier than the Q.
So im currently using a wired Filco at work. Which is nice, and quieter than the k12 (even tho both have silent reds).

I havent used Keychron wirelessly, so cant comment.
And I had to update the firmware to be able to use VIA, which involved a program and some scary messages. But it was straightforward.

If you have the budget for a Q Pro, then go for it. I love my Q, so I doubt you will regret it
