Keychron Q3 HE
8 owner reviews
“I am loving this kb, the rapid trigger is solid and the sound is surprisingly great for linear switches. Finally, I can jiggle peek correctly all the time without my kb holding me off. The keyboard looks and feels great!”
Keychron Q3 Ultra
4 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.”

Keychron Q3 HE vs Q3 Ultra: your questions
The main difference lies in the switch technology. The Q3 HE uses Hall Effect Gateron 2.0 magnetic switches, which offer adjustable actuation points and rapid trigger for gaming. The Q3 Ultra uses traditional mechanical Keychron Silk POM switches and is focused on a high 8K polling rate and extensive acoustic dampening with multiple foam layers.
The Keychron Q3 Ultra supports an 8000 Hz polling rate in both wired and 2.4 GHz wireless modes. The Keychron Q3 HE has a 1000 Hz polling rate in wired and 2.4 GHz modes, and 90 Hz over Bluetooth.
No, the Q3 HE is designed to be compatible exclusively with Gateron Double-Rail Magnetic switches. It does not support other magnetic or standard mechanical switches. The Q3 Ultra, however, is compatible with almost all 3-pin and 5-pin MX-style mechanical switches.
The Keychron Q3 HE is generally better for competitive gaming due to its Hall Effect switches that provide rapid trigger, adjustable actuation points (0.2 to 3.8 mm), and dynamic keystrokes, allowing you to assign multiple actions to a single key.
The Keychron Q3 Ultra has significantly better battery life, rated at up to 660 hours of use with the backlight turned off. The Q3 HE offers up to 100 hours under the same conditions.
The Q3 HE supports QMK firmware and the Keychron Launcher web app for remapping. The Q3 Ultra uses ZMK firmware and also works with the Keychron Launcher. They are different firmware ecosystems but both allow for extensive customization via a web-based tool.
No, both keyboards come with non-shine-through PBT keycaps. The Q3 HE uses OSA profile double-shot PBT, while the Q3 Ultra uses KSA profile double-shot PBT. This means the RGB lighting is more for ambiance than for illuminating the legends.
Both keyboards are 80% TKL layout. The Q3 HE is available in ISO-DE, ISO-UK, ISO-Nordic, ISO-SW, ISO, and ANSI standards. The Q3 Ultra offers ISO, ISO-DE, ISO-ES, ISO-FR, ISO-UK, ISO-CH, and ANSI.
The Keychron Q3 Ultra is more suitable for quiet offices because it includes multiple layers of acoustic foam, such as Sound Absorbing Foam, IXPE Foam, PET Film, and a Latex Bottom Pad, which are designed to reduce keystroke noise and vibration.
Based on user reviews, some buyers have reported USB connectivity dropouts even after firmware updates. Additionally, a user noted the lack of a visible Caps Lock indicator and the awkward placement of the rotary knob between keys as design flaws.
Yes, both the Keychron Q3 HE and Q3 Ultra come with a knob in their standard pre-built configurations. The Q3 HE's knob is described as part of a 'Fully Assembled Knob' version, while the Q3 Ultra features an 'All New Knob Design'.
Both keyboards are built with a CNC aluminum body and feel heavy and durable. The Q3 Ultra is slightly heavier at 1787g, compared to the Q3 HE at 1775g. Both are described as 'rock solid' in user reviews.
