“Works exactly as intended and still works as new. The 2.4 GHz Receiver doesn't communicate correctly and isn't reliable but on BT and Cable it works perfectly”

FAQ

AULA F75 vs Keychron B33: your questions

The Keychron B33 is explicitly designed for silent typing. Its vendor description highlights a scissor mechanism and fully pre-lubed keys for an ultra-quiet experience. The AULA F75 includes sound-dampening foam but uses traditional mechanical switches, which will be louder even if they are silent linear variants.

The Keychron B33 product listing does not mention hot-swappable sockets. It uses a proprietary scissor switch mechanism, which typically is not user-replaceable in the same way as mechanical switches. The AULA F75, in contrast, has confirmed full-key hot-swap functionality.

No. The Keychron B33 specifications list it as non-backlit. The AULA F75 features RGB backlighting with 16.8 million colors and offers both north-facing and south-facing LED orientations.

The AULA F75 has a 4000mAh battery. The Keychron B33 has an 800mAh battery but claims up to 320 hours of wireless use, suggesting more efficient power management. Actual battery life will depend heavily on usage patterns and, for the F75, whether RGB lighting is enabled.

Both keyboards list Mac support. The Keychron B33 has a system toggle and its Keychron Launcher web app is noted to be compatible with macOS. The AULA F75's dedicated software, however, is listed as supporting Windows only, though the keyboard's basic functions will work on Mac.

The AULA F75 uses Cherry-profile double-shot PBT keycaps, which are a standard shape and should be compatible with many aftermarket sets. The Keychron B33 uses low-profile ABS keycaps with a specific scissor mechanism, making it unlikely that standard mechanical keycaps will fit.

Both offer a 1000 Hz polling rate in their 2.4GHz wireless mode. However, the Keychron B33's Bluetooth mode operates at 125 Hz, while the AULA F75's Bluetooth polling rate is not specified. For consistent low-latency gaming, the 2.4GHz dongle is recommended for both.

The listed contents for the AULA F75 include the keyboard, a 2.4G dongle, a Type-C cable, a 2-in-1 keycap/switch puller, and a user manual. A wrist rest is not mentioned in the provided packaging details.

The AULA F75 case uses a combination of plastic and aluminum. The Keychron B33 case is made from ABS plastic, contributing to its lighter weight.

Yes, according to its vendor description. The Keychron B33 can be programmed using the Keychron Launcher web app, which allows for key remapping, macros, and shortcuts. The AULA F75 uses dedicated Windows software for customization.

For coding, the AULA F75 may have an edge due to its 75% layout which saves space while keeping essential keys, its hot-swap feature to choose preferred switches, and its included multimedia knob for quick controls. The Keychron B33's low-profile scissor switches offer a different, potentially faster but less tactile, typing feel.
