Keychron Q3 Ultra
Wireless 8K Showdown
- Tri-mode connectivity including 2.4 GHz, Bluetooth 5.3, and wired, with an 8000 Hz polling rate in 2.4 GHz and wired modes.
- Lighter weight at 1787g with a 4000mAh battery offering up to 660 hours of use (backlight off).
- Polycarbonate plate provides a softer, more flexible typing feel and contributes to a unique sound profile.
- Limited layout options primarily ISO and ANSI, with no JIS or other regional standards.
- Only one firmware option (ZMK) with a web launcher, lacking the offline flexibility of QMK/VIA.
- No barebones version available, forcing purchase of pre-built configuration.
If you are a modder, programmer, or need a highly customizable wired keyboard with QMK/VIA firmware, the Keychron Q3 is the better choice. If you prioritize wireless freedom, low-latency gaming, or a lighter travel keyboard, the Keychron Q3 Ultra with its 8000 Hz polling and long battery life is the way to go. Your decision ultimately comes down to whether wired customization or wireless performance matters more to you.

“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…”

“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 Q3 vs Q3 Ultra: your questions
Yes, the Keychron Q3 Ultra supports an 8000 Hz polling rate in both wired and 2.4 GHz wireless modes, as stated in the official specifications. It also offers Bluetooth 5.3 for connectivity, though the polling rate over Bluetooth is not specified and likely lower.
Yes, the Keychron Q3 comes in versions with or without a knob, and the knob version features a programmable aluminum rotary encoder. This knob can be customized via VIA software for tasks like volume control, zooming, or other macros.
The Keychron Q3 Ultra comes with KSA profile double-shot PBT keycaps. These are described as oil-resistant and durable with non-backlight shine-through legends, so they are not designed for RGB shine-through but are built to last.
The Keychron Q3 is generally better for programming due to its QMK/VIA support, which allows extensive key remapping, custom macros, and layers. It also offers more layout options (ANSI, ISO, JIS) to match different programming preferences, while the Q3 Ultra is limited to ISO and ANSI.
Yes, the Keychron Q3 features south-facing RGB LED lighting that is free from interference with Cherry-profile keycaps. The included ABS keycaps are shine-through, allowing the RGB to illuminate the legends from the typist's angle.
Both keyboards have a full CNC machined 6063 aluminum body, but the Q3 has a steel plate while the Q3 Ultra uses a polycarbonate plate. The Q3 also includes a double-gasket design with silicone pads for acoustic damping, contributing to a refined typing feel.
Yes, the Keychron Q3 Ultra supports hot-swappable switches, allowing you to install or change switches without soldering. It works with most 3-pin and 5-pin MX style switches, including Cherry, Gateron, and Kailh.
Yes, the Q3 Ultra includes a system toggle and an additional set of keycaps for both macOS and Windows. It supports Bluetooth 5.3 and 2.4 GHz wireless connections, making it compatible with both operating systems out of the box.
The Q3 Ultra has a 4000mAh rechargeable battery that provides up to 660 hours of use with the backlight turned off. With RGB at the lowest brightness, it lasts up to 200 hours, according to the manufacturer's specifications.
The Keychron Q3 Ultra is lighter at 1787g compared to the Q3's 2000g. Additionally, the Q3 Ultra's wireless capabilities (Bluetooth and 2.4 GHz) make it more portable since you can use it without a cable, while the Q3 is wired-only.
According to a user review, some units of the Q3 Ultra may experience USB connection drops even after firmware updates. It is recommended to check the latest firmware and compatibility with your system, as this issue has been reported on both Windows and macOS.
Yes, the Q3 Ultra uses ZMK firmware and can be programmed via the Keychron Launcher web app, which allows key remapping, backlight control, and macro customization. It does not support QMK, but the Launcher provides similar functionality through a browser-based interface.
