Coolkiller CK75 vs Keychron Q1 Max: your questions
The Keychron Q1 Max supports QMK and VIA firmware, which are open-source and allow for extensive key remapping, macro creation, and layer programming. The Coolkiller CK75 uses its own proprietary driver software, and its vendor description does not mention the same level of open firmware customization.
The Keychron Q1 Max is listed with a 1000 Hz polling rate in its 2.4 GHz and wired modes, which is beneficial for gaming responsiveness. Its heavy aluminum construction also provides stability. The Coolkiller CK75's vendor page does not specify a polling rate.

Both keyboards feature sound-dampening materials. The CK75 vendor description mentions a three-layer setup with Poron foam and silicone pads. The Q1 Max listing details multiple foam layers including IXPE, PET, and Latex, and a double-gasket design aimed at reducing acoustic resonance. The final sound depends on the installed switches.
Yes, both the Coolkiller CK75 and Keychron Q1 Max feature hot-swappable PCBs, allowing you to change switches without soldering. The CK75 supports 3-pin and 5-pin switches, while the Q1 Max is also compatible with most 3-pin and 5-pin MX-style switches.
The Coolkiller CK75 has a 3750mAh battery, while the Keychron Q1 Max has a slightly larger 4000mAh battery. The Q1 Max vendor page provides estimated wireless working times of up to 180 hours with backlighting off. The CK75 vendor description does not provide specific runtime estimates.
