Leobog Hi75C Pro vs K81 Pro: your questions
Both use gasket mount structures that provide a softer typing feel, but the Hi75C Pro's aluminium case and PORON foam may produce a deeper, more muted sound. The K81 Pro includes case, plate, and IXPE foam for acoustic control, so personal preference for sound profile will determine the better fit.
No, the Hi75C Pro does not include an LCD screen according to its specifications and vendor description. The K81 Pro is the model that features a built-in LCD display for visual feedback.
Yes, the K81 Pro supports tri-mode connectivity including Bluetooth 5.0, 2.4 GHz wireless, and wired USB-C as listed in its vendor specifications. This allows connection to multiple devices wirelessly.
The K81 Pro is lighter at 900 grams compared to the Hi75C Pro's 1230 grams, making it a more portable option for travel. Its acrylic and polycarbonate construction also reduces weight without sacrificing structure.
Yes, both the Hi75C Pro and K81 Pro feature hot-swappable PCBs that support 3-pin and 5-pin switches. This allows you to change switches without soldering for easy customization.
The Hi75C Pro has a 4000mAh battery, while the K81 Pro has a smaller 3000mAh battery. The larger capacity in the Hi75C Pro supports longer usage between charges when using wireless modes.
The Hi75C Pro vendor description indicates it is a pre-built kit, while the K81 Pro is sold as a barebones kit. The K81 Pro comes only with a switch and keycap puller and USB cable, meaning you must supply your own switches and keycaps.
The Hi75C Pro uses south-facing RGB, which typically works better with Cherry-profile keycaps for even lighting. The K81 Pro uses north-facing RGB, which can create brighter per-key illumination with OEM-profile keycaps and shines through keycaps more effectively.
Both the Hi75C Pro and K81 Pro use gasket mount structures. The vendor description for the Hi75C Pro specifies PORON gaskets, while the K81 Pro description simply lists it as gasket mounted.
Yes, the K81 Pro listing states it is compatible with both Windows and Mac operating systems. The Hi75C Pro also lists Mac/Win support in its metadata, so both keyboards work across platforms.
