Keychron K4 Pro vs K4 V2Programmable QMK vs Budget 96% Layout

The Keychron K4 Pro adds QMK and VIA firmware support for advanced key remapping, along with several hardware upgrades like sound-dampening foam, a silicone pad, screw-in stabilizers, and double-shot PBT keycaps. The K4 V2 is a more basic model that lacks these programmable features and premium build elements, often at a lower cost.

Both keyboards offer hot-swappable versions. The K4 Pro vendor page lists it as a standard feature. For the K4 V2, you must specifically select the 'Gateron G Pro Mechanical (Hot-Swappable)' version at purchase to get hot-swap sockets.

Both keyboards are fully compatible with macOS and include keycaps for Mac layout. The K4 Pro vendor description specifically mentions included keycaps for both Windows and macOS. The K4 V2 listing also states it has a Mac multimedia keys layout.

Both keyboards are listed with a 4000mAh rechargeable battery. The K4 V2 vendor page claims up to 240 hours of use with the backlight off. The K4 Pro's specific battery runtime is not detailed in the provided specifications, but the capacity is identical.

South-facing RGB means the LEDs on the K4 Pro are mounted on the south side (bottom) of the switch. This prevents the LED housing from physically interfering with the lower profile of Cherry-style keycaps, allowing for wider keycap compatibility and a better typing angle for backlight.

Yes, both use standard MX-style stems, so most Cherry MX keycap sets will fit. However, the K4 V2's north-facing LEDs may cause interference with some Cherry-profile keycaps, potentially making them feel scratchy or not seat fully. The K4 Pro's south-facing LEDs avoid this issue.

The K4 Pro is likely quieter out of the box. Its vendor description explicitly mentions added sound-absorbing foam and a thick silicone dampening bottom pad to create a more peaceful typing sound. The K4 V2's acoustic properties are not detailed in the same way.

In wired mode, both keyboards offer a 1000 Hz polling rate. In wireless mode, the K4 V2 vendor specifications list a 90 Hz polling rate. The wireless polling rate for the K4 Pro is not specified in the provided information.

No, neither keyboard includes a wrist rest in the standard package. However, the vendor pages for both models show optional resin or silicone palm rests available for separate purchase as add-on items.

The Keychron K4 Pro comes with double-shot PBT keycaps according to its vendor description. The Keychron K4 V2 comes with ABS keycaps, as listed in its specifications. PBT is generally more resistant to oil and shine than ABS.

Both the Keychron K4 Pro and K4 V2 can connect to up to 3 devices via Bluetooth, allowing you to switch between them. This is confirmed in the vendor descriptions for both models.
