About this item

Keychron K3, a compact 75% layout ultra-slim wireless mechanical keyboard built for peak productivity and a great tactile typing experience.
Be ready to multitask without missing a beat by connecting the K3 with up to 3 devices via the stable Broadcom Bluetooth 5.1 chipset and switch between your laptop, PC, tablet and phone seamlessly.
With a unique Mac layout, the K3 has all the necessary Mac multimedia keys while still being compatible with Windows. Extra keycaps for both Windows and Mac operating systems are included.
The redesigned low-profile Gateron mechanical switch is 40% slimmer than conventional switches with a shorter pre-travel and total travel distance that triggers an input and feedback faster than conventional/normal-profile mechanical switches.
Together with the reinforced aluminum body (plastic bottom frame) make the K3 one of the thinnest and lightweight wireless mechanical keyboards on the market. The K3 also comes with a floating keycap design with a charming white backlight with modern keycap legends to sync with your mood.

5.0 out of 5 stars Excellent reasonably priced slim mechanical TKL keyboard!
Reviewed in the United States on August 1, 2022
I've been looking for a slim TKL mechanical keyboard for a long time. I've read about the Keychron products, but hesitated to pull the trigger because other brands had more reviews with similar ratings. I shouldn't have and hope my review will help others who are relying on the number of reviews to make an informed decision.

This little beauty is the best slim TKL mechanical keyboard I've tried by a long shot! The form factor is perfect, quality is great (especially given the very reasonable price) and it feels and works great! I might end up buying one or two more, one for the office and the other just so I have a replacement for when this one wears out. I have not tried using it in wireless mode or using it with a Mac. The default key configuration is for Mac, but there are spare key caps to replace Mac specific keys with Win (which I promptly did :) ). It is small enough to leave plenty of space on your desk, yet heavy enough to not move about when you type. The keyboard comes with brown mechanical switches, which are smooth and quiet enough to not annoy people sitting around you.

All keys are mapped correctly to their designated functions. I'm actually using it with a Chrome book, was super impressed that all the keys do what they said they would, even the screenshot button.

All in all, I've very happy with my purchase - great product Keychron!

5.0 out of 5 stars Excellent keyboard
Reviewed in the United States on 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.

5.0 out of 5 stars Keyboard product design is a fine art. And this is the masterpiece.
Reviewed in the United States on March 16, 2023
As a "fussy keyboard user" I buy many keyboards at no expense spared. I'm not sure there's any keyboard I like much more than this at any price.

I bought this for travel but really I may use it all the time.

The price, basically if it was about two times the price it is, I'd still pay it.

It appears to me much better made than, say, steel series keyboards at 3x the price. (And steel series keyboards flake out after a year.)

As everyone has said (a) it feels rock, rock, rock solid, strong and heavy (b) it's super-low profile (c) the connectivity is perfect (I normally only go for wired, so I'm very critical of anything bluetooth) (d) every product feature is perfectly thought out.

My only SUGGESTIONS for the product team. Just add a sticker, or white printing, on the rear of the keyboard, with the two commands one needs to know to start it up, etc. (I just grabbed a "white paint pen" and wrote the commands on the back.)

Secondly, may I suggest selling some sort of "travel guard" which would be a very strong kind of clip- or slide- on guard which goes over the keys, for when you throw it in your carry-on luggage. (Imagine something that looks like an aerox mouse, with a drilled surface.)

Essentially, this is a perfect product. I chose the "most quiet, fastest, zero click" blue switches and they're perfect. I am a programmer and writer so I type billions of words and command-arrow type clicks a day.

I've added two "size comparison to typical objects and other overpriced keyboards", hope it helps someone

5.0 out of 5 stars Will need another cable if your computer only has USB-C ports
Reviewed in the United States on November 5, 2021
Great keyboard, the ultra-slim is perfect for me because I keep my keyboard and keyboard tray underneath my desk, and so there needs to be enough clearance for my hands. Connected via bluetooth with no problems. However, I would like to warn others that this came with a USB-A to USB-C cable, and that the keyboard port is USB-C. I was expecting the other way around, since I have a Macbook with only USB-C ports. So, I had to find another USB-C to USB-C cable, to charge the keyboard. Once I did that, it seems to have worked fine!

Only downsides are, I can't quite tell when I have auto-off mode on, or off. I'm not sure if there's an indicator somewhere that I can't see. When I first started using the keyboard, there seemed to be a bit of lag. I searched the internet, people suggested turning off the auto-off, and I think that helped, but it's annoying that I can't easily visually tell whether it's on or off.
