Cidoo ABM098 vs Keychron K4 Pro: your questions
Both keyboards are designed with sound dampening. The Cidoo ABM098 uses a gasket mount with Poron PCB foam, an IXPE switch sheet, and a silicone bottom pad. The Keychron K4 Pro includes sound-absorbing foam and a thick silicone dampening bottom pad. The Keychron also offers pre-lubed linear and tactile switch options, which the manufacturer states are smoothed for a quieter experience.

Yes, both keyboards feature south-facing RGB LEDs. The manufacturers for both the Cidoo ABM098 and Keychron K4 Pro state that south-facing LEDs avoid interference with Cherry-profile keycaps, making them compatible.
The Keychron K4 Pro offers broader software customization. It supports both the open-source QMK firmware and VIA, allowing for extensive key remapping and macro programming through the Keychron Launcher web app. The Cidoo ABM098 is programmable with VIA software but does not list QMK support.

The Cidoo ABM098 uses a gasket mount, where the plate is suspended by rubber or silicone gaskets to dampen sound and vibration.

Both are available as pre-built units with switches and keycaps. Additionally, the Keychron K4 Pro is also sold as a barebone kit, which includes the case, PCB, and plate but no switches or keycaps, for those who want to build from scratch.
Both keyboards are listed with the same 4000mAh battery capacity. Actual battery life will depend on usage patterns, backlight brightness, and connection type, but their maximum potential capacity is identical.

The Keychron K4 Pro lists a 1000 Hz polling rate, which is a standard spec for responsive gaming. It also features N-key rollover to prevent ghosting. The Cidoo ABM098 also has N-key rollover, but its polling rate is not specified in the provided information.
Both keyboards have hot-swappable PCBs that support the vast majority of common mechanical switches. The vendor pages for both the Cidoo ABM098 and Keychron K4 Pro confirm compatibility with standard 3-pin and 5-pin MX-style switches.
