Ajazz AK871 vs Keychron K2 MaxBudget Wireless vs Premium Custom

The Keychron K2 Max is specified to have a 1000 Hz polling rate on its 2.4GHz connection and Bluetooth 5.1. In contrast, user reviews for the Ajazz AK871 report very poor 2.4GHz range and reliability, making the K2 Max the more dependable wireless option.

Both keyboards support macOS. However, the Keychron K2 Max includes a dedicated set of Mac keycaps and a system toggle switch. The Ajazz AK871 supports Mac via a function key combination but does not include Mac keycaps, as noted in a vendor review response.

The Keychron K2 Max is built with materials aimed at improving acoustics, including multiple foam layers (IXPE, PET, EPDM), a steel plate, and screw-in stabilizers.

The Keychron K2 Max is more compact in width (317mm vs 362mm) and slightly lighter (940g vs 970g), giving it a slight edge for portability. However, the Ajazz AK871 uses disposable AAA batteries, which can be convenient for travel if you don't have access to a charger.

The Keychron K2 Max uses double-shot PBT keycaps, which are more resistant to wear and shine. The Ajazz AK871 uses ABS keycaps, which are common in budget keyboards but can develop a shiny surface with prolonged use.
