According to the vendor, the TFT screen on the AULA F75 Max is customizable and can display GIFs, animations, system information like battery life and connectivity status, and be used to control RGB lighting effects. It adds a layer of personalization and utility.

Yes, both the AULA F75 Max and the Redragon EISA K686 Pro feature hot-swappable sockets. Their listings confirm compatibility with both 3-pin and 5-pin mechanical switches, allowing you to easily change switches without soldering.

The AULA F75 Max is more portable. It is significantly narrower (328mm vs 430mm) and lighter (960g vs 1060g) than the Redragon K686 Pro. Its 75% layout is much easier to pack in a laptop bag compared to the 90% layout with a numpad.

Yes, both product listings explicitly include Mac and Windows support. The Redragon's description also mentions a side button for seamlessly toggling between the two operating systems.

Both keyboards use a gasket mount design. This mounting style uses silicone or foam gaskets to isolate the plate from the case, which typically results in a softer, more cushioned typing feel and helps reduce sound resonance.

Both keyboards come with pre-lubed linear switches. The AULA F75 Max includes LEOBOG Reaper switches, while the Redragon K686 Pro includes Red Linear switches. The Redragon also includes four spare switches in the box.

Based on vendor descriptions, both have extensive sound-dampening. The AULA F75 Max lists an IXPE pad, PET pad, and layered foams. The Redragon K686 Pro mentions a 3.5mm PO sound-absorbing pad, two dampening foams, and a silicone gasket. Both are designed for a quieter, more thocky sound.

Yes, both keyboards support key remapping and macro editing through their respective software. The AULA F75 Max vendor description highlights this for both the keys and the lighting effects. The Redragon listing also confirms software support for creating macros and new lighting modes.

The AULA F75 Max has a 4000mAh battery. According to its specifications, this provides up to 30.5 hours of use with the RGB backlight on, and up to 80 hours with the backlight off. The Redragon's battery capacity is not specified in the provided information.

Both are designed for comfort with gasket mounts and low-profile designs. The AULA F75 Max specifically mentions a low front height and a 2-stage adjustable kickstand for ergonomics. The Redragon K686 Pro listing notes its design provides a softer typing feel with vertical cushioning. Preference may come down to the switch type and keycap profile.
