Keychron B4 Pro Ultra-Slim Wireless Keyboard 96 Bluetooth 2 4 GHz Wired Connection Keyboard with Numeric Keypad Launcher

I got the all-white version, and it’s gorgeous. I’ve bought a lot of different keyboard styles over the years—gaming boards, loud clicky ones, typewriter-style builds, foldable portables, Bluetooth everything—and this one immediately stood out in a way I wasn’t expecting. Everything feels like it was actually thought through. A lot of keyboards show up with odd design choices or missing features, and since we use these things constantly, the little flaws become major annoyances. This one avoids all of that. It feels premium, but more importantly, it’s practical and saves time. I’ve used it every day for about two weeks. I’ll keep this review updated if anything changes or if any issues pop up. The tri-mode setup is excellent - all the connections are instant and reliable. The keyboard never loses connection and I can't feel or sense any delay or lag or missed inputs etc. The hardware switch on the back makes it easy to avoid draining the battery, the battery itself is solid, and charging is quick. FN + 1–4 for Bluetooth and 2.4GHz slots is a lifesaver when you switch devices a lot. The physical toggle for wired/Bluetooth/2.4GHz makes the whole thing simple and fast. The silicone cover is a huge bonus. It takes the board from “quiet” to “basically silent.” It also keeps dust, crumbs, and spills out of the keys, which matters a lot with this style of switch. It fits perfectly and genuinely changes how the keyboard feels. About the typing experience: I’ve seen people say the key travel is too long or feels off, and I really disagree. The keys feel fantastic. The travel is smooth and short, and there’s no weird play in any of them. Scissor switches aren’t meant to be wobbly anyway, and that’s exactly what I feel here - everything is tight and precise. Even the space bar feels great. It’s consistent whether you hit it on the left, middle, or right with no dead spots or strange tilt. I’ve used this for a lot of email and writing, and I’ve put in a decent amount of gaming time just to see how it holds up. It’s surprisingly great for gaming. Not because it’s designed for that, but because it’s snappy, smooth, and completely silent. I also like how compact yet feature-rich this 96% layout is. You keep all the important keys without the desk-space penalty. Strengths: Extremely quiet; finger taps are louder than the switches. Smart tri-mode implementation that makes switching fast and easy. Silicone skin that improves sound, feel, and protection. Smooth, short key travel with no wobble. Compact layout without giving up functionality. Complaint: No backlight. For a board this good, that’s the one thing missing. Read more

I absolutely love this keyboard! It's the nicest keyboard I've used for under $50. It's so convenient that it has both a wireless dongle and Bluetooth – I like being able to effortlessly switch from my Macbook to my PC. And as much as I enjoy my mechanical keyboard, it's an adjustment since I use low-profile keyboards most of the time for work. So when I need to be able to type effortlessly and quickly, this keyboard now my go to because it is so much nicer than my laptop keys, and has a numpad. It's lightweight without feeling cheap, and it comes with a silicone cover – the description mentions being able to type with it on but I'll just use it for keeping dust off. I just need to get a case for it and it'll be my new travel keyboard. Seriously for the price and functionality, I highly recommend this keyboard! Read more

Within a few dollars, this is basically the same price as the B2 and B3 models, but a full keyboard. When you buy this, you are buying it for the form factor and because you know the ergonomics are strange and you are okay with this. If you are surprised when it isn't as good as your laptop, or mechanical keyboards, you should not blame Keychron for that. Is the keyboard good? Not really. It has scissor switches and they are passable, but the larger keys, notably the spacebar, are rather unstable and have a lot of play on pressing down. They should have made the switches a bit tighter and more rigid. Buy this for looks, not for function. Read more

I’ve been using this with my work laptop for a while now, and I really like it. The connectivity options are great- I can’t use Bluetooth with this laptop, so the included dongle is a nice touch. It also connects via USB, and includes a USB C cable, plus an adapter for USB A. I have not tried it on Mac yet, but I also have a C3 Pro, and the Mac mode on that keyboard is perfect. Obviously this keyboard has chiclet keys - although I prefer a standard keyboard, I find this one very nice to type on. Read more

For $39.99, this is a steal—definitely recommend! Read more

This keyboard is absolutely fantastic! The ultra-slim design looks clean and elegant, and it feels solid without being bulky. Typing is smooth and responsive, and I love having the full layout with a numeric keypad, it makes work so much easier. The wireless options are super convenient, and switching between Bluetooth, 2.4 GHz, and wired mode is seamless. Battery life has been great too, and it pairs perfectly with both my laptop and desktop. Whether I'm working or just browsing, it feels comfortable and fast. A great upgrade for anyone who wants performance and style in one keyboard! Read more

This has a nice design, and the size is great. I hate when keyboards are too small and this isn’t. Keys work well and so does connection. Read more
