Review: Yunzii B75 Pro Max wireless mechanical keyboard
Review unit provided by Yunzii
The Yunzii B75 Pro Max is a 75% 81-key wireless mechanical keyboard released in late 2025. Price at the time of review is USD 84.99.
This keyboard is a variation of the Yunzii B75 Pro (top). The main visible difference is the Pro Max version has moved the Delete key below the knob so as to fit a display.

Design
The keyboard is available in four colours: black, beige, white heart and pink heart. All four designs look quite good but I'm not a fan of transparent keycaps that the black model has. The red and pink models have a heart design which looks pretty and cool.
My review unit is the beige and I like the colour combination.
As a Mac user, I'm happy to say that there's a right-Cmd key but unfortunately the right-Ctrl is still a right-Ctrl instead of a right-Opt.
The keyboard supports QMK/VIA customisation via the VIA online tool which does not require installation. And customising the keys requires a JSON file that can be downloaded from this website. There's no right-Opt key with VIA customisation.
The keyboard supports connection with 2.4Ghz (with USB-A receiver), Bluetooth to three devices and cable connection.
The foldout feet can be deployed at two heights. Overall build quality of the keyboard is good although if you flex the body there will be some flex.
The keyboard uses PBT double shot keycaps with Cherry profile.
The switches available are all linear-type: Candy, Cocoa Cream V2 and Milk V2.
Typing experience is wonderful. My review unit came with the Candy linear switches and the thic-thoc sounds creamy, sound so good compared to the Milk switch I had with my other keyboard. Typing sound is not noisy so this keyboard won't be disturbing people in the office.
Key layout is quite standard and easy to get used to, even with the Delete key below the knob and on the right of Backspace. One downside for me is there does not seem to be anyway to switch Fn shortcuts with Fn keys which are by default F1 to F12.
The TFT display and volume control knob are located at the top right.
The display has 160 x 96px resolution and can show information for date, time, battery life, connection type, OS, caplock, winlock, an image or animated gif. Customising the display with your own image and animated gif requires use of Yunzii's website. Uploading your image or animated gif requires a cable connection. Uploading process is straightforward. And on the website is also where you can set the date and time of the display.
The display is bright enough to see the photo or animated gif, but it's difficult for me to take a photo because my camera always shows the display at low brightness.
The RGB lights are beautiful and there are many patterns to choose from. You can adjust the brightness, speed, direction using keyboard shortcuts.
If you have the lights on all the time, battery life is around 4-5 days. Without the lights, battery life can last for weeks. Battery life for this keyboard is considered very good because 8000 mAh battery capacity is huge and many other wireless keyboards usually comes with just 4000 mAh.
Conclusion
The Yunzii B75 Pro happens to be my main keyboard that I've been using for more than a year now and I really enjoy using that keyboard. Since the Yunzii B75 Pro Max uses almost the same design, it's a great keyboard too. The review unit came with the Candy linear switches and the thic-thoc sounds more dampened and less sharp compared to the Milk linear switches in my other keyboard. I love the typing sound of the Candy linear switch.
The extra display to me is nice to have but not really a must-have.
One huge upgrade is the battery capacity has increased from 4000 mAh to 8000 mAh. Perhaps the "Max" refers to that. I do not have any issues with the battery life of my previous keyboard but having longer battery life is always appreciated.
Bottom line is this is a great keyboard selling at a reasonable price and provides good value for money.
