Keychron K2 Pro vs Yunzii YZ75Software vs Gasket Mount

The Keychron K2 Pro has significantly more advanced software support. It is compatible with the open-source QMK and VIA firmware for extensive key remapping and macro creation. The Yunzii YZ75's vendor description does not mention comparable advanced programming software.

The Yunzii YZ75 listing states Mac and Windows support, but its layout is listed only as ANSI. It does not offer ISO or UK layout keycaps. The Keychron K2 Pro explicitly supports ISO layouts, including UK, and includes keycaps for both Mac and Windows.

The Yunzii YZ75 uses a gasket mount, where the plate is suspended on rubber gaskets, aiming for a softer, more flexible typing feel. The Keychron K2 Pro uses a tray mount (and PCB mount), where the plate is screwed directly into the case, typically resulting in a firmer, more consistent feel.

The Keychron K2 Pro's vendor page states its K Pro switches (excluding clicky ones) are factory pre-lubed. The Yunzii YZ75 description mentions it comes with Gateron G Pro switches but does not specify if they are pre-lubed; it does confirm the stabilizers are pre-lubed.

Based on the listed specifications, the Keychron K2 Pro has a larger 4000mAh battery compared to the Yunzii YZ75's 3100mAh battery. This suggests the K2 Pro has the potential for longer use between charges, though actual battery life depends on usage patterns and lighting.

Yes, both offer moddable stabilizers. The Keychron K2 Pro uses screw-in PCB stabilizers and supports third-party replacements. The Yunzii YZ75 comes with pre-lubed stabilizers on a hot-swappable PCB, which also allows for removal and modification.

Yes, both keyboards feature south-facing RGB LEDs. The Keychron vendor description specifically notes that south-facing LEDs prevent interference with Cherry-profile keycaps, making them compatible. The same should apply to the YZ75 due to its south-facing design.

Yes, according to its vendor description, the Yunzii YZ75 supports a 2.4 GHz wireless connection and includes the wireless dongle in the box. The Keychron K2 Pro connects via Bluetooth 5.1 and wired USB-C, but does not list a 2.4 GHz mode.

The Keychron K2 Pro comes with OSA profile double-shot PBT keycaps. The Yunzii YZ75 uses XDA profile PBT dye-sublimation keycaps. These are different shapes, with OSA being sculpted and XDA being a uniform, flat profile.

Keychron offers both hot-swappable and non-hot-swappable versions of the K2 Pro. The vendor description clearly notes that the 'Black - Fully Assembled' version is NOT hot-swappable and lacks sound foam. Buyers must select the 'Fully Assembled (Hot-Swappable)' or 'Barebone' variants for hot-swap capability.

Both have sound-dampening features. The K2 Pro includes sound-absorbing foam and a silicone pad, while the YZ75 has double layers of sound-absorbing foam. The final sound will depend more on your switch choice. The K2 Pro's availability of silent K Pro switch options, as shown in its vendor page, may give it an edge for quietness.
