Over the years, we’ve tried a handful of YUNZII keyboards and always had a good time. Their boards are typically built to be a true out-of-the-box experience: you get pretty much everything you’d want right away, plus a genuinely pleasing sound profile, without having to mess around with internals or swap parts to make it feel “complete.”
Even better, while YUNZII does have a few models that push past the $100 mark, most of their lineup still delivers a surprisingly premium experience at ridiculously affordable prices. And this is one of those keyboards. The YUNZII B75 Pro Max lives up to the “Pro Max” name with very few real compromises on paper. Now let’s see how it holds up in practice.

DESIGN
As the name suggests, the YUNZII B75 Pro Max is a 75% keyboard with 81 keys. Size-wise, it’s exactly what you’d expect from the layout: compact, but slightly wider than a pure “tight” 75% thanks to the extra navigation cluster (the Delete / End / Page Up / Page Down group) sitting to the right of the alphas, just above the arrow cluster.
The main keys and that side column are broken up by a small, genuinely useful status strip with indicator LEDs for Caps Lock, Win Lock, and wireless connection modes. The real standout, both visually and functionally, is of course the knob and the small TFT screen in the top-right corner. I’ll get into what they actually do a bit later, but from a design standpoint, both elements feel like they belong here – especially on the black B75 Pro Max model we’re reviewing.
Yunzii spiced up the black variant with really beautiful transparent keycaps
While the Pink Heart and White Heart variants will absolutely fit right into cozy, white-dominant setups, and Beige is clearly aimed at the retro crowd, the Black two-tone version feels like the obvious pick. Not just because it pairs best with the darker screen area, but also because it highlights the other standout feature of this colourway: the keycaps.
YUNZII’s keycap choices on the B75 Pro Max are a great example of how small details can give a keyboard real personality, and I honestly wish more brands took this approach. On the black model in particular, most of the alphanumeric keys are solid black, so they don’t really show off the south-facing RGB underneath, but the keys along the sides are translucent, and that single design decision adds a ton of character.

Even better, that transparency comes in two flavours. The keys on the far right (and parts of the left-side row) use a darker, more smoked translucent plastic that mutes the RGB, while the lighter translucent keys are much clearer and turn into a proper light show when the lighting is on.
Each colourway also ships with a small set of extra novelty keycaps, and as far as I can tell, the black variant is the most distinctive: not only does it lean into the translucent theme, but it also brings a subtle coffee shop aesthetic with little icons like coffee beans, cups, croissants, cakes, and similar details. It’s a fun touch that adds a bit of cozy charm – even on a colourway you wouldn’t normally associate with that vibe.

Other than that, the only design details really worth calling out are on the back edge of the keyboard. There’s a small control cluster in the middle with the USB-C port, a mode switch for toggling between wireless options, and, always appreciated, a dedicated storage slot for the USB wireless dongle. On the underside, you get two-stage kickstand feet and rubber pads around the edges to keep the board from sliding around, even if you’re using it directly on a bare desk without a mat.
BUILD AND FEEL
Don’t let the two-tone colourway fool you: the B75 Pro Max is an all-plastic board. That said, if I didn’t review keyboards for a living, the weight alone might have convinced me otherwise. At just under one kilogram, it feels surprisingly heavy and sturdy in a way you don’t normally associate with plastic cases. A big part of that is obviously the battery, but it’s still nice to see that YUNZII’s “solid, no-nonsense” philosophy carries over even on a non-aluminium model – especially since my previous YUNZII experience has mostly been with their more tanky metal boards.
There’s no key rattle, no creaking, and no flex even when you really manhandle it. Part of that comes down to how packed the internals are, which is a bit of a double-edged sword on a board like this. YUNZII markets the B75 Pro Max as a gasket-mount keyboard, but the generous amount of dampening material means the typing surface doesn’t really have that typical gasket bounce or flex.
Two tone transparency gives the keyboard a ton of personality
Under the gaskets you’re looking at multiple layers: sound foam, a switch pad, switch film, and then under the PCB there’s PCB foam plus a silicone dampener. That isn’t necessarily a bad thing, but it’s worth keeping in mind if you’re expecting a classic, softer gasket feel with a noticeably flexible deck.
If a firmer, more stable typing surface isn’t a dealbreaker for you, the upside is clear: the sound profile here is genuinely excellent – and honestly far better than you’d expect at this price point.
Cocoa Cream V2 Switches are really the golden middle ground of what’s available with B75 Pro Max
It lands somewhere in the middle between creamy and thocky – a slightly weird category, I know, but it’s incredibly satisfying to listen to. A lot of enthusiasts spend a ton of time (and money) trying to tune custom boards into this kind of sound profile, and here you’re basically getting it right out of the box.
That unusually good sound is probably helped by the particular configuration on my review unit, which combines those layered internals with YUNZII’s own Cocoa Cream V2 linear switches. They’re rated at 50g operating force, with a 2.0mm actuation point and 3.3mm total travel. On paper, they’re the sweet spot among the switch options YUNZII offers for this keyboard – and in practice, they’re super smooth and feel great for both gaming and typing.
PERFORMANCE
Like the other YUNZII boards we’ve tested, the B75 Pro Max supports tri-mode connectivity: wired, 2.4GHz via USB dongle, and Bluetooth. On the wireless side, it can pair with up to five devices. You might not ever need that many, but it’s a genuinely handy feature if you’re bouncing between machines in a busy office setup or switching devices throughout the day.
Most of my testing was split between wired and 2.4GHz, and the 2.4G connection was impressively reliable – honestly close to wired in terms of consistency. Bluetooth is also solid, and for the kind of use cases it’s meant for, it does the job perfectly well: quick typing sessions on a laptop, a tablet, or any other Bluetooth-enabled device.
Tri-mode connectivity is reliable and super convenient
Now, this isn’t a hardcore esports weapon, and it doesn’t really pretend to be one, but it’s still a great pick for anyone who doesn’t need absolute peak multiplayer responsiveness. I played games like Dragon’s Dogma, Borderlands 4, and No Man’s Sky on it without any issues. That said, typing is definitely where this keyboard shines the most, and that’s where I got the most enjoyment out of it – if nothing else, because of that super satisfying sound profile.
Wireless life is backed by a massive 8,000mAh battery, and how long it lasts will obviously depend on how you run it. With RGB and the TFT screen enabled, expect around 5–7 days. Turn those battery hogs off, and you’ll practically forget the keyboard even needs charging. Outside of RGB testing, I kept the lighting disabled most of the time – and after two weeks of use, the screen’s battery indicator still showed three out of four bars, which is genuinely impressive.
The TFT screen is more of a gimmick best used to showcase images and GIF’s
When it comes to the screen specifically, its implementation is a bit hit-or-miss for me. From a design standpoint it fits the keyboard really well, especially since you can load images or GIFs, but as an actual “info display” or command centre, it’s only partly useful.
The most valuable thing it shows is the battery status. Time and date are nice to have, but they’re lower on the usefulness list when you’re usually sitting at a PC anyway. Everything else the screen can display is basically a duplicate of what you already get from the status LEDs: connection mode, Win Lock, and Caps Lock.
LED’s do a better job of giving you the necessary information
The fact that the knob looks visually tied to the screen is also a little misleading, because you don’t actually control the screen with it. Instead, you use a couple of preset shortcuts to cycle between an image, a GIF, or the info screens. And beyond that, the screen can’t be managed through VIA/QMK at all – you have to use a separate YUNZII online driver, where the options are pretty basic: upload images/GIFs and manually update the time and date.
If nothing else, I’m genuinely glad YUNZII switched to QMK/VIA here, because their older models relied on proprietary software that felt pretty bare-bones and honestly wasn’t great to look at. With VIA/QMK, there’s also no real friction. Once you’ve got the JSON file loaded, you’re basically a couple of clicks away from everything you’d expect from proper keyboard customisation – macros, RGB controls, key remapping, layers, and more, without having to wrestle with a clunky, brand-specific app.
CONCLUSION
All things considered, the YUNZII B75 Pro Max is exactly the kind of keyboard that reminds you why the brand has such a strong reputation for out-of-the-box value. It looks fun, sounds genuinely satisfying, and offers a feature set that feels unusually complete for something that’s still very much in the “affordable” category.
At $70-$85, it’s honestly hard not to be impressed by how much you’re getting. Yes, the all-plastic build is clearly the main reason the price stays this low, and the TFT screen is a feature that ends up feeling better on paper than it does in real day-to-day use. But outside of that, the B75 Pro Max hits almost everything you could reasonably want from a budget-friendly board: tri-mode wireless, a big battery, a solid stock typing experience, hot-swap flexibility, and proper QMK/VIA support.
If you’re after a relatively inexpensive keyboard that feels “done” the moment you take it out of the box, without needing mods, tuning, or extra spending – this could definitely be the one.
