Our Analysis

The Keychron K3 version 2 is a compact and lightweight mechanical keyboard that has managed to impress with its overall performance and versatility. What we found most notable is the keyboard's comfortable typing experience, attributed to its Low Profile 2.0 Mechanical switches, which were consistently praised across multiple expert reviews. The simultaneous connection to three devices over Bluetooth and the swappable switches for customization are additional strengths, providing users with the flexibility to tailor the keyboard to their preferences. Moreover, the 75% layout is a thoughtful inclusion, combining compactness with functionality, as it retains arrow keys and a function row without adding unnecessary bulk. Despite these positives, some reservations have been expressed regarding the low-profile switches, which may not be to everyone's liking, and concerns about reduced battery life compared to its predecessor.

The Keychron K3 version 2 impresses with its slim design, variety of mechanical and optical switches, and compatibility with both Mac and Windows devices. Its swappable switches allow for customization without needing a new device. However, the slim profile results in a short battery life, and the exposed key design necessitates a protective pouch for travel, which is an additional cost.

Excellent keyboard

Spirit of 76 June 12, 2022
I’ve used a lot of keyboards going all the way back to the original IBM PC. Most modern keyboards feel mushy to me. This feels great.I bought both the brown and the blue switch variations. The blue had a great feel, but its relatively high-pitched click was annoying. The brown is closer to a Goldilocks switch, quiet and with good tactility, although just a tiny bit mushy. I chose the K3 for its low-profile design, as I had read that the standard Keychron keyboards are very thick and need wrist rests. The K3 at only 7/8" thick feels fine without one. Key travel is also quite good. Fresh out of the box, I don’t seem to have lost any typing speed compared with the MacBook Pro keyboard which I’ve been using for the last few years.I haven’t had any problems with the Bluetooth connection. I have it paired with three devices – an iMac, a MacBook Pro and an iPad Pro. Just a few seconds each to pair initially, then no trouble with any of them. Switching between devices takes just a couple of keystrokes. As a Mac user, I really like that the media function keys work out of the box and are labeled properly. Likewise the command and option keys. I have no real need for the backlighting and certainly not for all the fancy, flashy chasing light modes. It’s a keyboard, not a theater marquee. But I do find it handy to have on at minimum brightness when I have to work in a darkened room.If there’s one thing I wish Keychron offered, it’s a low-profile numeric keypad to go with this. I didn’t want a full-size keyboard like the K5 which would force me to reach pretty far for my trackpad. But a numeric keypad comes in handy when I have to type in more than few digits, and it would be nice to have one to put to the right of the trackpad.

Excellent slim keyboard with great features

Francesco C. September 11, 2025
I’ve been using the Keychron K3 Version 2 for a few weeks, and I’m really impressed. The sound quality is satisfying, key presses feel tactile and have a pleasant click without being too loud. Bluetooth connectivity is smooth and stable; I can easily switch between devices without any lag.The brightness adjustment for the backlight is intuitive and bright enough to type comfortably even in dark rooms. All the keys function perfectly, including the function row and multimedia shortcuts.The overall keyboard quality feels solid yet lightweight, and the slim design is perfect for my desk setup. It’s also highly compatible with Windows, macOS, and iOS, making it very versatile. Overall, it’s an excellent keyboard for both work and casual use, and I would highly recommend it.

Great for a first mechanical keyboard! Easy typing.

uebergeek October 11, 2025
My first mechanical keyboard(s)! Got one for work, and I liked it so much, I bought one for home too. In between, I tried a fancier one from another brand that offers a million switch options, thinking I was buying quieter switches – but they were actually louder. At twice the price, I liked that keyboard less than the simpler K3, so I sent it back and just bought another one of these.The K3’s keys (with red switches) are fast for programming and command line work. The key height is good. The keyboard Bluetooth pairs to my Mac and PC just fine, and you can easily toggle the Mac/PC layout. That said, it does take a moment to “wake up” and reconnect in Bluetooth mode (as many switchable keyboards do), so I tend to keep it plugged in via USB unless I need it wireless. I like that it has a USB connection option – not all multi-device BT keyboards do.The key backlights are helpful, especially for nightowls, though I prefer to just keep the backlights in static mode. Maybe all the chasing light modes are fun for gaming, but I find them distracting for work. And in bluetooth mode, it somehow seems to switch the lighting mode periodically, so I frequently find myself having to cycle it back to find the static one. One-star off for that minor nuisance, but otherwise, great typing experience.If you aren’t a mechanical keyboard connoisseur who needs programmability and swappable switches, this is a nice basic setup that seems “just right.” If you’re not sure which type of switches to order it with, I’d recommend the red switches for an easy typing experience and switches that are relatively quiet – as mechanical keyboards go.

Excellent compact keyboard, very well made, especially for the price.

Cameron O'Rourke January 12, 2026
This is a great keyboard. Note that this is a compact keyboard – it is just a little smaller than a standard sized keyboard, but it is made really well, with a metal base plate – feels very sturdy. The keys feel great and the backlighting helps see the keys in the dark. It connects via USB or Bluetooth, and can switch between three different devices with a keystroke. Also comes with key caps for both Mac and Windows.

Excellent keyboard. The size, build quality, and key quality are all very good. I don’t really need all the RGB lighting modes, but there are plenty of them. It connects to devices very quickly, and I’ve had no issues with connection stability or quality.This is my first mechanical keyboard, so it felt unusual for the first couple of months, and I still occasionally hit the wrong keys — mostly because of the compact size. Overall, though, everything is great.Personally, I would choose slightly heavier switches to avoid accidental key presses. The battery lasts about 2–3 days with constant backlighting. I usually keep the backlight at 50%, and in that case the keyboard lasts much longer — about a week for me. I don’t game; I use it for work about 7–9 hours a day.Final thoughts: I recommend it. The size can be both a plus and a minus — it takes some getting used to — but the quality is impressive. I would choose heavier keyboard switches; mine are red switches.

The Verdict

The Keychron K3 version 2 is a genuinely impressive compact mechanical keyboard, delivering multi-device Bluetooth connectivity, hot-swappable switches, and a comfortable low-profile typing experience in a slim 75% layout that retains arrow keys and a function row. It earns its place as one of the better portable mechanical keyboards at its price point. The low-profile switches are an acquired taste for some, and battery life is slightly reduced compared to its predecessor — but neither concern should overshadow what is an otherwise well-rounded and versatile keyboard.
