UK Keychron K3v2 Bluetooth RGB Optical Tactile Ultra-slim Aluminium Mac/PC 75% Keyboard - K3-E3-UK

Incorporating the world's first hot-swappable low profile Optical switches to customize per-key typing experience with ease, together with all signature Keychron features.


Connects via Bluetooth and switch among 3 Bluetooth devices easily and 1 wired device. Featuring Bluetooth 5.1 chipset, the K3 offers flawless connectivity whether you're working at home or the office while connecting with your smartphone, laptop and iPad.

  • Connects with up to 3 Bluetooth devices
  • Broadcom Bluetooth 5.1
  • USB Type-C connection

The redesigned low profile switch is 40% slimmer than conventional switches. Together with the streamlined aluminum body makes the K3 one of the thinnest and most lightweight wireless mechanical keyboards in the world.
Compatible for both macOS and Windows. Keychron is one of only a few in the market that comes with a Mac multimedia keys layout for Mac enthusiasts. For Linux users, we also have a dedicated user group to help with the experience.
Two level adjustable rubber feet makes the new K3 more comfortable to type on.

We all have our unique typing preferences, that's why we went the extra mile to make the K3 the world's first hot-swappable low profile Optical switch keyboard. We've implemented an MX-styled stem and stabilizers, and conducted numerous design iterations of the keyboard structure.
You can easily hot-swap every Optical switch to customize your typing experience on the K3 without soldering. *Hot-swappable feature is available for low profile Keychron Optical switch version only.

With the MX-styled stem housing and ultra-low latency, the low profile Keychron Optical switches are crafted for typists or gamers who want to type at lightning speed with a lifespan much greater than industry standards.
*Low profile Keychron Optical switch keyboard is not compatible with any conventional mx style mechanical switch.

  • Light actuated
  • 0.2ms Ultra-low latency
  • 70 million keystroke lifespan

We've spent over a year developing and implementing a MX-styled stem on both the low profile switches for the K3 as well as stabilizers on the big keys like the space bar, left Shift, backspace and Enter key.
It will improve reliability, deliver better typing experiences, and may potentially pave the way for other keycap manufacturers to launch alternative keycaps.

Crafted for productivity, the K3's 75% layout is a compact version of tenkeyless layout. It allows users access to all the essential multimedia and function keys, but with a smaller footprint.

Comes with various RGB backlight settings, you can adjust the keyboard brightness to sync with your mood.

Quite a change from the much-loved but very noisy Filco Majestouch boards I bought it to replace, but better suited to my post-PhD, typing-fast-but-not-touch-typing knackered hands, for two main reasons. First, with the brown Keychron switches and the slim profile there is less key travel and less reaching, but still a really nice precise feel. Second, though I miss the number pad, there is less desk space taken up to the right, and I have to reach less for my mouse.

I couldn't care less about the RGB lights and haven't done much testing with the Bluetooth connection, though it paired happily with two Linux laptops, so the early signs are good. I've used it mainly with a Windows laptop and a Linux desktop, using the USB cable. It's precise and a good typing experience though the layout, particularly the location of the Pg Up, Pg Dn, Home, and End keys has taken me a short while to get used to.

The four-star rating is solely because of the bluetooth latency problem which another reviewer has referred to, whereby in the midst of some very fast typing the cursor freezes and then appears to get stuck, churning out hundreds and hundreds of whatever letter last registered with the USB receiver. This has only happened once - compared to the dozens of times it used to happen with the Filco Majestouch 2 - but it's still bloody annoying when it does happen.

I haven't had any difficulty with slow reconnections after the keyboard sleeps, as referred to by other reviewers, but this may yet be early days.

Overall, very happy with the board but it loses a star from the full 5 for the latency issue.

Really like this keyboard, feels great to type on and the Bluetooth connectivity and the spare keys provided allow for it to be set up for mac or windowsLinux.

Excellent Apple Magic Keyboard replacement. I would avoid the red switches unless you really need a silent typing experience, as they're very prone to typos. Battery life on this board leaves a lot to be desired compared to the K2 or other larger Keychron models. However, the portability of this board is second to none and at this price point it's excellent value. As always the Keyboard Company's service is excellent - fast communication and shipping

The keyboard looks amazing, comes with great accessories in a gorgeous box. It is well built and works great out of the box with my M1 Mac. Delivery, handling and communication with was good. Over all it is nice improvement over my M1 Air keyboard. The optical brown switches are fairly quiet but feel a bit less distinct than I hoped for. My husband has a Logitech G915 with low profile blue switches and he prefers the keycaps and switches.
Overall it works great for me. Potential improvements for the next version: volume wheel, longer battery life, swappable batteries, faster BT wake up, Software to configure it, different keycap options, brighter RGB, larger letters, del key and light key should be switched, the plastic (dust) cover should have a cut out for the cable, so it can be used while charging, USB hubpassthrough if used wired would be nice --- BUT compared to what is available on the market, this is the best bang for buck and even in isolation a highly recommended keyboard.

Great keyboard, Great support by It is very light and feel good to type. I hope next generations will have more battery life. It lasts about 3-4 days after full day usage.

Love the product, and also arrived quicker than anticipated! I kept glancing over at my colleagueon site IT engineer guy at work who was using one of these and really sold me on the product, being 75%, low profile, the hot-swappable keys themselves and simply just the look of the keyboard. The box that it comes in is also really nice!!

I've held off on this review for over a month so I can test those features that receive some criticism online. 5 stars for The Keyboard Company for prompt service and great packaging. The keyboard itself is wonderfully tactile and a joy to use. I don't miss the numeric keypad. The Bluetooth is the reason I'm knocking one star off. It's a little annoying at times. Can take a few seconds to connect after going to sleep. Sometimes a couple of seconds and sometimes a little longer. The time to go to sleep mode can be altered and (I believe) switched off. It's a minor gripe. A more significant drawback is that after waking up from sleep mode the keyboard can generate the same letter multiple times on the screen due to some latencyconnection issues. This happens most days. Overall I'd recommend this keyboard as almost all of the time it performs well. I don't use the cable (which would cure the Bluetooth performance issues). Charge lasts approximately 2 weeks when I use the keyboard around 6 hours per day. Good purchase overall. :-)

I love the keyboard, it feels great to type on, and frees up a lot of space on the desk compared to the full size wired one I had before. There are loads of reviews which explain it far better than I ever could! However I'd like to say special thanks to KeyboardCo - I placed my order on Friday afternoon (sorry guys) and had it in my hands by Monday morning. If you look on the manufacturer's website there are several complaints from people who have been waiting weeks. That's too stressful! Without hesitation I would buy from Keyboard Co again.

It arrived perfectly packaged. The keyboard itself is great, it has a good variety of light modes, and it feels very nice to type on. The only issue I have is some of my keys are squeaking but I hope it will fix itself after continued use.

Very nice low profile and relatively compact keyboard. Excellent upgrade from laptop keyboards that I had been using without going to the bulk of the admittedly nice but higher profile switch versions of the Keychron.

Easy for me start touch typing quickly (with my poor technique!!) on a long essay. Sound with the Brown Optical switches is pleasant to my ear and they have a subjectively nice actuation force and bottom out point to them. Good Bluetooth switching between devices with low latency and USB connectivity.

RGB lighting is nice but only switchable via the on-keyboard button, though luckily there are a few options I don't find garish. ABS keycaps so will eventually go shiny and few other officially compatible alternative options if they are not to you liking.

this is best replacement for mac keyboard the backlaight on K3 is better than on k8 although the feelings are a bit softer comparing with full-size key-caps and standard size mechanical switches.

keyboardco was wery helpful and proactive.

Upgraded from an Apple Magic Keyboard and can't go back now. The brown switches are useable on calls or in the office without bothering people. Dispatched & delivered on time. Great keyboard, Great service.
