Build quality in the top 5% of 80% boards under $300.
- CNC machined 6063 aluminum body with double-gasket design and silicone pads between the top and bottom cases.
- Tri-mode connectivity covers 2.4 GHz at 1000 Hz polling, Bluetooth 5.1 to three devices, and wired Type-C.

- South-facing LEDs. Shine-through legends stay dark, and some sculpted keycaps can clip the LED.
Choose the Keychron C3 Pro if wired competitive gaming, an 8000 Hz polling rate, and a lighter 912 g body are the priorities, and the ABS plastic case is an acceptable trade. Choose the Keychron Q3 Max if you want a CNC aluminum chassis, tri-mode wireless with a 4000 mAh battery, a knob, and ISO layout options, and the higher cost and 2045 g weight are acceptable. The primary differentiator is connectivity and materials, not switch choice, since both boards are hot-swappable and QMK/VIA capable.

What will you mostly use it for?
The C3 Pro takes gaming and travel on the strength of its 8000 Hz polling rate and lighter plastic body. The Q3 Max sweeps office, programming, modding, and content creation because of its aluminum construction, tri-mode wireless, knob, and layered acoustic foams. Buyers who mostly play competitive games wired will find the C3 Pro's feature set aligned with that use. Those who split time across devices or want a heavier, more tunable board will lean toward the Q3 Max.
Pick the Keychron C3 Pro
- The C3 Pro supports an 8000 Hz polling rate, switchable among 1000, 4000, and 8000 Hz through the Keychron Launcher web app.
- Wired-only Type-C connectivity avoids wireless latency variables entirely.
- The lighter 912 g body is easier to reposition during play than the 2045 g Q3 Max.

Keychron C3 Pro vs Q3 Max: your questions
No. The C3 Pro is listed as a wired-only keyboard with Type-C connectivity. Buyers who need Bluetooth or 2.4 GHz should look at the Keychron Q3 Max, which supports both plus wired Type-C.
The Q3 Max runs a 1000 Hz polling rate on 2.4 GHz and wired modes, which Keychron positions for low-latency play. Its Bluetooth mode drops to 90 Hz, so competitive play is better served by 2.4 GHz or the cable.
The C3 Pro supports up to 8000 Hz, switchable among 1000, 4000, and 8000 Hz through the Keychron Launcher web app. The Q3 Max tops out at 1000 Hz on 2.4 GHz and wired, and 90 Hz over Bluetooth.
Yes. Both the C3 Pro and Q3 Max accept most 3-pin and 5-pin MX style mechanical switches without soldering. The Q3 Max also offers a barebone kit option if you want to supply your own switches and keycaps.
The Q3 Max uses a CNC machined 6063 aluminum body with a double-gasket design and silicone pads between the top and bottom cases. The C3 Pro uses an ABS plastic case with steel or plastic plate options, which is lighter but less rigid.
The Q3 Max includes a 4000 mAh rechargeable li-polymer battery rated up to 180 hours with backlight off and up to 100 hours with RGB at the lowest brightness. The C3 Pro has no battery because it is wired only.
Keychron lists macOS and Windows support for the C3 Pro, with an FN + Caps Lock shortcut to switch between systems. The Q3 Max adds Linux to its compatibility list and ships with both Mac and Windows keycaps.
The C3 Pro weighs 912 g versus 2045 g for the Q3 Max, and its wired-only design removes battery and charging concerns on the road. The Q3 Max is heavier and better suited to a fixed desk setup.
Yes, the Q3 Max is offered in Fully Assembled Knob and Barebone Knob versions, and knob support is listed among its features. The Q3 Max also lists multi-media keys, which the C3 Pro does not.
The C3 Pro ships with Cherry profile double-shot PBT shine-through keycaps, which Keychron says resist oil and keep legends from fading. The Q3 Max uses KSA double-shot PBT keycaps that are not shine-through, or optionally OSA side-printed shine-through keycaps.
Yes, both list QMK and VIA support, and both can be configured through the Keychron Launcher web app for key remapping and macros. Keychron notes the Launcher works best in the latest Chrome, Opera, or Edge browser.
The Q3 Max offers ANSI plus ISO variants including UK, German, Nordic, and Swiss layouts. The C3 Pro is listed with ANSI only, so non-US layout users will find more choice with the Q3 Max.
