Keychron Q2 HE vs Q4 HE65% vs 60% Hall Effect Keyboard Comparison

The core difference is the layout and connectivity. The Q2 HE is a 65% keyboard with arrow keys and offers an 8000 Hz polling rate but is wired-only. The Q4 HE is a 60% keyboard without dedicated arrow keys and provides full 2.4 GHz and Bluetooth wireless connectivity with a 1000 Hz polling rate.

No. According to Keychron, each keyboard has limited compatibility. The Q2 HE 8K is compatible exclusively with the Keychron Ultra-fast Lime Magnetic Switch. The Q4 HE is compatible exclusively with the Gateron Double-Rail Magnetic Switch.

The Keychron Q4 HE is designed for wireless use. It supports both 2.4 GHz and Bluetooth 5.2 connections and includes a 4000mAh battery. The Q2 HE 8K model is a wired-only keyboard and does not have wireless capabilities.
