“I've owned my Q2 Max for half a year now and I'm very satisfied with this keyboard. This keyboard checks off all the boxes for me and has performed excellent for the past 6-7 months.”
Keychron Q3 Ultra
5 owner reviews
“USB is working for me, but I have it plugged in to a USB switcher. I haven't configured the keyboard, beyond the switches in the back. I'm liking the keyboard so far.”
“USB on keeps dropping out, even after firmware update (1.0.2) and reset. Tried multiple computers, windows and Mac. Half the time it doesn’t work at all.”

Keychron Q2 Max vs Q3 Ultra: your questions
The Keychron Q3 Ultra has a higher polling rate of 8000 Hz in both wired and 2.4 GHz modes, as stated by the vendor. The Keychron Q2 Max has a 1000 Hz polling rate in wired and 2.4 GHz modes and 90 Hz over Bluetooth. For competitive gaming, the Q3 Ultra offers lower potential latency.
Yes, the Keychron Q2 Max is listed as having both QMK support and VIA support, as well as the Keychron Launcher web app. This allows for extensive key remapping, macro creation, and layout customization.
Yes, the vendor page for the Keychron Q3 Ultra states it is hot-swappable and compatible with most 3-pin and 5-pin MX style mechanical switches. This allows you to change switches without soldering.
Both the Keychron Q2 Max and the Keychron Q3 Ultra have a 4000 mAh rechargeable li-polymer battery, as specified in their respective product details.
Yes, the Q2 Max's extra features include knob support, and the vendor sells a 'Fully Assembled Knob' version. The Q3 Ultra also comes with a knob.
The fully assembled version of the Keychron Q3 Ultra comes with pre-lubed Keychron Silk POM Switches. The vendor offers Red (linear), Brown (tactile), and Banana (tactile) options.
The Keychron Q2 Max is better for a small desk due to its more compact 65% layout. Its dimensions are 21 x 121 x 328 mm, which is significantly smaller than the Q3 Ultra's 31 x 365 x 137 mm.
Yes, the Keychron Q3 Ultra uses ZMK firmware and the Keychron Launcher web app, which allows you to create macro commands, shortcuts, and key combinations, as described on the product page.
The Keychron Q3 Ultra is heavier at 1787g, compared to the Keychron Q2 Max's 1528g. Both are heavy due to their full aluminum construction, but the Q2 Max is the lighter option.
No, the vendor descriptions for both the Keychron Q2 Max and the Keychron Q3 Ultra specify that their keycaps are 'non-backlight shine through' PBT material. This makes the keycaps more durable but limits the usefulness of the RGB backlight for reading legends in the dark.
The Keychron Q3 Ultra uses ZMK open-source firmware, as stated by the vendor. This is a key difference from the Q2 Max, which uses QMK firmware.
Based on the provided information, the Q3 Ultra lacks a Caps Lock indicator. A user review explicitly mentions this as a negative. The Q2 Max product page does not mention a Caps Lock indicator, but its QMK/VIA support technically allows programming the Caps Lock key's backlight as an indicator, though this is not a separate physical LED.
