Keychron K4 Max vs Q5Wireless vs Full Metal

The Keychron Q5 generally offers a more refined typing sound due to its double-gasket design and full aluminum case, which reduce metallic resonance. The K4 Max features multiple layers of acoustic foam (IXPE, PET, EPDM) for a quieter sound, but the Q5's construction provides a deeper, more solid acoustic profile.

Yes, both keyboards support QMK and VIA firmware, allowing full key remapping, macro creation, and shortcut customization. You can use the Keychron Launcher web app on both. The Q5 also includes a programmable knob that can be configured through VIA.

The Keychron K4 Max is the better choice for wireless use, as it supports both 2.4 GHz and Bluetooth 5.1 connections and has a large 4000mAh battery. The Q5 is a wired-only keyboard with no wireless capability.

The Keychron K4 Max has an ABS plastic case and a steel plate, making it lighter and more portable. The Keychron Q5 features a full CNC machined 6063 aluminum case and a steel plate, resulting in a heavier, more premium feel with better acoustic damping.

Yes, the Keychron Q5 is available in barebones kit form, which includes the case, PCB, plate, and stabilizers without switches or keycaps. This allows for complete customization. The K4 Max is only offered as a pre-built keyboard.

Only the Keychron Q5 includes a programmable rotary knob, which can be customized via VIA software for functions like volume, zoom, or screen brightness. The K4 Max does not have a knob.

The Keychron K4 Max comes with OSA profile double-shot PBT keycaps, which are durable and resistant to oil. These keycaps are more resistant to shine over time compared to ABS keycaps.

The fully assembled Keychron Q5 comes with OSA profile ABS backlight shine-through keycaps. These allow the south-facing RGB LEDs to shine through clearly, but ABS may show wear faster than PBT.

The Keychron Q5 is significantly heavier, weighing 2310g (plus or minus 10g), due to its full aluminum case. The Keychron K4 Max weighs 1290g, making it much lighter and easier to transport.

Yes, both keyboards include a system toggle and additional keycaps for both macOS and Windows systems. This allows you to save and switch between two different layouts, one for each operating system.

Both the Keychron K4 Max and Keychron Q5 have a polling rate of 1000 Hz in wired mode. The K4 Max also offers 1000 Hz polling in 2.4 GHz wireless mode for low-latency gaming.

Yes, both keyboards feature hot-swappable PCB sockets that support 3-pin and 5-pin MX style mechanical switches, allowing you to change switches without soldering.
