Keychron K4 Max vs Q4Wireless 96% vs Wired 60% Aluminum

The Keychron K4 Max is designed for wireless use, supporting 2.4 GHz and Bluetooth 5.1 connections in addition to wired mode. The Keychron Q4 is a wired-only keyboard and does not offer any wireless functionality.

No, the Keychron Q4 is a 60% layout keyboard. It does not have a numpad, dedicated arrow keys, or a function row. All these functions must be accessed through a secondary layer using key combinations.

The Keychron Q4 features a full body made from CNC machined and anodized aluminum, giving it a premium, solid metal construction. The Keychron K4 Max uses an ABS plastic case, but includes a steel plate and multiple internal foam layers for sound dampening.

Yes, both keyboards support full programmability using the open-source QMK firmware and the VIA/Keychron Launcher web app. This allows for extensive key remapping, macro creation, and layer configuration on either board.

The Keychron Q4 is significantly more portable due to its compact 60% size, measuring 303mm in length. The K4 Max is a 96% layout and is 391mm long. However, the Q4 is heavier for its size due to its metal case.

Yes, both the Keychron K4 Max and the Keychron Q4 feature hot-swappable PCBs. They support both 3-pin and 5-pin MX-style mechanical switches, allowing you to change switches without soldering.

The fully assembled Keychron Q4 comes with double-shot PBT keycaps in the OSA profile. According to the listing, these are not shine-through keycaps. The kit also includes extra keycaps for both Windows and macOS layouts.

The Keychron Q4's double gasket design places gaskets on the plate and adds silicone pads between the top and bottom aluminum cases. The manufacturer states this reduces acoustic resonance and metal impact noise while maintaining typing flexibility.

Yes, the Keychron K4 Max includes a system toggle switch and an additional set of keycaps for both macOS and Windows. The manufacturer states you can save two different layouts on the keyboard, one for each operating system.

The Keychron K4 Max listing shows options for Keychron Super Red, Brown, or Banana switches. The fully assembled Keychron Q4 comes with pre-lubricated Gateron G Pro switches (Red, Blue, or Brown). Both are hot-swappable if you wish to change them.

Both keyboards have sound-dampening features. The K4 Max uses IXPE, PET, and EPDM foam layers. The Q4 uses a gasket mount and silicone pads to reduce noise. The final sound depends heavily on your switch choice, but both are designed to mitigate loud acoustics.

Yes, the Keychron Q4 is offered in a barebones kit version. This kit includes the aluminum case, PCB, steel plate, and stabilizers, but does not include switches or keycaps, allowing for a fully custom build from the start.
