There is little overlap in their core missions, making this a decision based on connectivity versus construction.

What will you mostly use it for?
The K3 Pro is the clear choice for mobile and multi-device workflows, winning in Gaming, Office, and Travel due to its wireless features and portable form.

“For anyone buying this, remember to toggle the switch to the correct operating system. Other than that, the feel is good and it comes with a good feature set for a low price”
“I was happy at the beginning but after few months of use I'm getting more and more frustrated. Keyboard just hangs sometimes and I'm not able to connect with BT. I use it to operate two laptops and using Fn+1 anf Fn+2 combination is great... when it works…”

“I upgraded from the Q1 as I never really liked 75%. The weight, sound and feel of the Q3 are all amazing. Really good build quality. Money well spent.”
“I thought I had found exactly what I wanted and its great for what it is, but! This was advertised as an ANSI layout but what I received was an ISO layout board. The barebones board also states in the images that it comes with switch and keycap removal tools…”

Keychron K3 Pro vs Q3: your questions
No, the Keychron Q3 is a wired-only keyboard. It connects via a USB Type-C cable and does not offer Bluetooth or 2.4 GHz wireless connectivity.
No, the Keychron K3 Pro is only compatible with Gateron low-profile mechanical switches. The vendor page explicitly states it does not support standard MX-style or low-profile optical switches.
Both keyboards offer full Mac compatibility with included keycaps. The K3 Pro vendor description emphasizes it has the same multimedia and function key functions as Apple keyboards. The Q3 also includes a system toggle and keycaps for both macOS and Windows.
The Keychron Q3 is available in both knob and non-knob versions. The fully assembled knob version includes a programmable aluminum rotary encoder that can be customized via VIA software.
The K3 Pro uses a tray mount system, while the Q3 uses a more advanced double-gasket mount. The gasket mount in the Q3 uses silicone pads to isolate the plate and PCB from the case for a softer typing feel and altered acoustics.
Both support QMK/VIA firmware for deep software customization. For hardware, the Q3 offers more modding potential with its gasket mount, screw-in stabilizers, and compatibility with all standard MX switches. The K3 Pro's modding is limited by its low-profile switch requirement.
The Keychron K3 Pro has a 1550mAh battery. The vendor description does not provide an estimated battery life, as it will vary greatly with usage patterns and backlight settings.
The K3 Pro uses Low-profile Spherical-Angled (LSA) profile keycaps. The Q3 ISO version uses OSA profile keycaps, which the vendor describes as an OEM profile with a spherical angle.
Both are available as pre-built options. The K3 Pro is listed as a pre-built board. The Q3 is available as both a fully assembled keyboard and a barebones DIY kit, allowing you to install your own switches and keycaps.
The Q3 is likely quieter in stock form due to its sound-dampening design. Its vendor description highlights a double-gasket design with silicone pads to reduce acoustic resonance and noise. The K3 Pro's acoustics are not specifically described with dampening features.
Yes, both the Keychron K3 Pro and Q3 support key remapping and macro creation. They are compatible with the open-source QMK firmware and the VIA/Keychron Launcher web app for easy programming without flashing.
The Keychron Q3 has a fixed typing angle of 5 degrees, as listed in its specifications. The Keychron K3 Pro does not list a fixed angle but offers three levels of adjustable typing angle via its feet for ergonomic support.
