FAQ

Leobog Hi75C Pro vs Yunzii AL66: your questions

The Yunzii AL66 comes with extensive pre-installed sound dampening foams and a polycarbonate plate, which are designed to create a more muted and consistent typing sound. The Leobog Hi75C Pro uses a gasket mount with PORON gaskets for a softer feel, but its vendor description does not list the same level of internal foam. Preference depends on whether you want a pre-tuned acoustic experience or a more standard foundation.

The core product metadata lists it as wired only. However, the vendor product description explicitly states the Hi75C Pro model has tri-mode connectivity (wired, 2.4G, and Bluetooth) with a 4000mAh battery. It is crucial to confirm which version you are purchasing from the retailer, as specifications may differ.

Yes, the Yunzii AL66 product listing confirms compatibility with Windows, macOS, and Linux. Both keyboards use a standard ANSI layout and connect via USB-C, making them broadly compatible with modern operating systems.

Yes, both the Leobog Hi75C Pro and the Yunzii AL66 feature hot-swappable sockets. The Yunzii listing specifies support for both 3-pin and 5-pin switches. This allows you to easily install different mechanical switches without soldering.

The Yunzii AL66 is more portable. It has a 65% layout with 66 keys, making it significantly smaller than the 75% Hi75C Pro. The AL66 is also lighter, weighing 1145g compared to the Hi75C Pro's 1230g, and both offer wireless connectivity for cable-free use.

The product metadata lists the switch type as clicky. The vendor description further details a 'Yunzii Milk Switch' variant that is linear. This suggests different switch options may be available, so check the specific listing when purchasing to see which switch is included.

Yes, both keyboards feature RGB backlighting with south-facing LEDs. South-facing LEDs are often preferred as they improve compatibility with Cherry-profile keycaps and can reduce glare. The Yunzii AL66 also includes side case lights according to its description.

The Leobog Hi75C Pro has a 4000mAh battery according to its vendor description. The Yunzii AL66 has a slightly larger 4600mAh battery as listed in its specifications. Both should offer good battery life for wireless use.

Both keyboards feature a control knob. The Leobog Hi75C Pro's vendor description says its knob can switch between work/gaming modes and control volume and lighting. The Yunzii AL66 listing states its metal knob can control RGB modes, brightness, or volume.

The Yunzii AL66 specifically lists Cherry profile dye-sublimated PBT keycaps. The Leobog Hi75C Pro vendor description does not specify the keycap material, so they may be made of a different material like ABS.

The Leobog Hi75C Pro uses a 75% layout with 81 keys. It retains the function row, arrow keys, and a few navigation keys like Insert and Delete in a compact block. The Yunzii AL66 is a 65% layout with only 66 keys, removing the function row and navigation cluster, requiring the use of keyboard layers to access those functions.

The Yunzii AL66 supports N-key rollover for accurate multi-key presses and has wireless connectivity for a clean desk setup. However, its 65% layout means common gaming keys like the function row must be accessed via a layer, which could be less convenient than the dedicated keys on the 75% Leobog Hi75C Pro.
