AULA F75 vs Machenike K500F B81: your questions
Only the AULA F75 offers wireless connectivity. It supports Bluetooth, 2.4GHz wireless, and wired USB-C. The Machenike K500FB81 is a wired-only keyboard.
Yes, both the AULA F75 and the Machenike K500FB81 feature hot-swappable sockets. This allows you to change the mechanical switches without soldering.
The AULA F75 is equipped with a 4000mAh rechargeable lithium battery. The manufacturer states this provides extended usage times, though exact battery life in hours will depend on usage patterns and RGB lighting settings.
The Machenike K500FB81 is marketed as a clear mechanical keyboard. This refers to its transparent case design, which is available in colors like Clear Purple, Clear White, Clear Black, and Clear Green, allowing its internal components and RGB lighting to show through.
The AULA F75 is specifically designed for a quieter experience. Its vendor description highlights a five-layer sound and shock-absorbing internal design, including two layers of Poron foam, an IXPE switch pad, a PET pad, and a bottom silicone pad to reduce typing noise and resonance.
Both product listings include Mac/Win support in their specifications. However, for the AULA F75, the downloadable software is noted to support Windows systems only, which may limit customization on macOS.
According to its vendor page, the AULA F75 includes the keyboard, a 2.4G dongle, a Type-C cable, a 2-in-1 keycap/switch puller, and a user manual.
The Machenike K500FB81 offers a choice between GR-ICE Linear switches and GR Crystal Tactile switches. The vendor describes the linear switches as smooth and ideal for typing, and the tactile switches as having a strong rhythm sensation, recommended for gaming.

The AULA F75 has a polling rate of 1000 Hz. This is a standard high rate for gaming that helps ensure fast and responsive keypress registration.
The Machenike K500FB81 offers full-key anti-ghosting (N-key rollover) and its tactile switch option is marketed as being recommended for gaming. However, as a wired-only board, it lacks the wireless low-latency option and rapid trigger feature found on the AULA F75.
