What will you mostly use it for?
The AULA F75 Ultra wins in more categories, particularly where extended battery life, ergonomic adjustability, and deep software customization are critical, such as for office work, programming, and modding. The Ajazz AK820 Pro takes the lead for travel due to its lower weight and slimmer form. For gaming, the AULA's detailed latency specs give it an edge, while content creators might value either the Ajazz's screen or the AULA's macro capabilities equally.
Pick the AULA F75 Ultra
- The AULA F75 Ultra lists a specific 1000 Hz polling rate and provides latency figures (5-6ms wired, 7-9ms 2.4Ghz).
- Its product description explicitly mentions anti-ghosting and N-key rollover support for fast-paced games.
- The Ajazz AK820 Pro also has a 1000 Hz polling rate per its specs, but the AULA provides more detailed performance claims for gaming.

Ajazz AK820 Pro vs AULA F75 Ultra: your questions
The AULA F75 Ultra has a significantly larger 10000mAh battery compared to the Ajazz AK820 Pro's 4000mAh. The AULA's vendor claims a battery life of up to 320 hours with RGB lighting turned off, which far exceeds the runtime you can expect from the Ajazz model.
Yes, but the method and depth differ. The AULA F75 Ultra supports VIA software, allowing for extensive, browser-based remapping of every key, layer creation, and macro programming. The Ajazz AK820 Pro does not list VIA support, so its customization may be limited to onboard shortcuts or proprietary software not detailed in the provided information.
No, both keyboards offer a 1000 Hz polling rate in their wired and 2.4GHz wireless modes. The Ajazz vendor specifications confirm a 1k polling rate, and the AULA F75 Ultra explicitly lists a 1000 Hz polling rate in its technical specs.
The Ajazz AK820 Pro is more portable. It weighs 810g (0.8kg), which is 290g lighter than the 1100g AULA F75 Ultra. The Ajazz is also slightly thinner, with a height of 40mm compared to the AULA's 43mm.
According to the vendor, the 0.85-inch TFT screen on the Ajazz AK820 Pro serves as an interactive interface. It can display customizable visuals, battery status, the date and time, current connectivity mode, operating system, and backlight effect settings.
The AULA F75 Ultra features a five-layer sound optimizing system. As per the vendor description, this includes sandwich foam, a switch pad, a sound-enhancement PET sheet, a switch socket pad, and bottom foam to reduce case echo and create a creamy typing sound.
Both keyboards primarily use PBT keycaps. The Ajazz AK820 Pro uses double-shot PBT keycaps. The AULA F75 Ultra uses PBT keycaps for its White/Blue colorway and PC (polycarbonate) keycaps for its Transparent Black colorway.
The AULA F75 Ultra is better for ergonomics. It has a three-stage adjustable kickstand that provides typing angles of approximately 5, 7.3, and 9.7 degrees. The Ajazz AK820 Pro does not mention any adjustable typing angle in its provided specifications.
Yes, both the Ajazz AK820 Pro and the AULA F75 Ultra feature hot-swappable sockets that support both 3-pin and 5-pin mechanical switches. This allows you to easily change switches without soldering.
The Ajazz AK820 Pro listing mentions options like the Ajazz Gift, Flying Fish, and Dreamy switches, all linear. The AULA F75 Ultra listing mentions factory-lubed options like the LEOBOG Strawberry Mint or Reaper switches, also linear. The specific switch included may depend on the variant you purchase.
Yes, both keyboards list Mac compatibility in their extra features. The Ajazz AK820 Pro vendor notes you can switch between Win and Mac modes via its TFT screen. The AULA F75 Ultra specs state compatibility with Mac, but note it does not include Mac modifier keycaps.
The Ajazz AK820 Pro has a substantial number of verified user reviews, with a 4.6/5 score from 725 reviews. The AULA F75 Ultra listing shows no customer reviews available, so its real-world performance is less documented by users.
