Best low profile, 75% keyboard for the Mac. Period.

I have been looking for a good low profile keyboard for my Mac. I have even tried more expensive ones. This is easily the best one. They keys have the right profile for easy typing and keycaps (brown) are just perfect for home office use. The keyboard is customizable and programmable - so super flexible for all kinds of shortcuts for those into them.

I come from a traditional TKL cherry mx keyboard that I have used for over 5 years. But after using this for just a couple of days, I really don't feel like going back. I find this experience much closer to my mac's keyboard - which makes it super easy to move between both as needed. I also think I am making fewer typos with this one. I plan to soon take this apart and customize the already good sound, further - as they say make it mine :-)

Shipping was super quick too. Ordered it from the US on a Thursday - and received it on Monday the following week (4 days)! All in all, very happy!!

Perfect except for 1 Bluetooth issue on Windows startup

This keyboard has everything I wanted but one annoying problem for me.

Pros:
Size was super important for me
* One of the smallest length keyboard for a 60% -75% layouts
* Despite having the F-row, the front to back width is only 116mm, super compact!
* Almost no bezel makes the keyboard small and the keys look like they just float.
* More ergonomic than my 100% keyboard since my mouse can now be closer.
Others
* Bluetooth connection, I don't want to have wires on my desk.
* Programmable keys

Cons:
Bluetooth issue
* I put my Windows PC to sleep when I'm not using it. When I try to wake it up by pressing any button on the K3 Pro it does not wake my computer up. I need to click my mouse to wake it up instead.

When I try to put in my password after my computer wakes up, it takes around 3 key presses before the keyboard works. This is very annoying and gives me a poor experience when I log in. This problem does not occur when the keyboard is wired but the reason I choose to buy this keyboard was so I don't have to use the wire.

My personal favorite

Keychron's regular K3 was my first mechanical keyboard, which I bought a little over two years ago now. I really liked the compact form factor and the low-profile switches, which are a must for me if I want to be able to type quickly and accurately. However, there were downsides to the keyboard. Although the aluminum base felt sturdy and had a high-quality feel, the contact points (i.e., the keys) did not. Moreover, for reasons that are not quite clear to me, I found myself having more typing errors with the chicklet-style keycaps. Thus, I set aside my normal K3 and ventured on to other models from Drop and Ducky, just to name a few.

One day, Google happened to recommend to me an article about a new K3 Pro keyboard Keychron was releasing through Kickstarter. As soon as I saw the changes from the original model, I strongly suspected this would easily place as my new favorite. I was not wrong.

The keycaps are much improved, it sounds great (to my admittedly novice ears), and I really like the eye-catching-yet-understated keycap colors, which are perfect for my office. I know it has other features, which I frankly don't use. To me, it was well worth the money (and Kickstarter wait-times) to upgrade from the original K3, which has been relegated to my laptop bag for occasional use out of the office. Total home run in my book. (I will note that Jordan is correct that the RGB does not really shine through the keycaps, but, again, it provides just enough flair without being gaudy in my office, so that is not a problem for me.)

AMAZING!!

I have not bought a Keytron product before and the K3 is amazing! I love this keyboard. It connects to all my devices and the switches feel great typing on them. They are not loud like the traditional clicky sound you get from a mechanical so it is okay to use in an office setting. I use the keyboard on both Windows and Mac with no issues. If you are planning to travel with the keyboard I recommend get the travel case as the keyboard fits snug and will protect the keyboard from scratching when traveling with it. Also, keep in mind this keyboard is very small too. The images do not do justice on how small this keyboard is. If you do not like compact this one is not for you but if you want a small keyboard to travel or just like the small footprint then this is perfect for you. The colors are great and the red enter key and esc key make a good contrast as well. I have the RGB option and it comes with a lot of color variations and color sequences too. This is a cool feature to have but does not make or break the device for me.

K3 Pro

Keychron K3 Pro QMK/VIA Low-Profile Wireless Mechanical Keyboard with an ultra-slim body and hot-swappable

The Keychron K3 Pro is the world’s first low profile wireless mechanical keyboard with QMK/VIA enabled for endless possibilities. 

Everyone can easily customize any key or create macro commands through the VIA software on the ultra-slim yet durable K3 Pro.

Features of Keychron K3 Pro

Wireless and Wired

An excellent solution for multitasking. Connects the K3 Pro with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking across your laptop, phone, and tablet. Switch among them swiftly, and it’s fully compatible with both Mac and Windows.

You can also enjoy a USB Type-C wired connection with 1000 Hz polling rate which is engineered for the competitive game. 

Keychron K3 Pro QMK/VIA Low-Profile Wireless Mechanical Keyboard

Ultra-Slim

The innovative low-profile Gateron switch is 31% slimmer than conventional normal profile switches makes the aluminum body K3 Pro one of the thinnest wireless mechanical keyboards in the world. While still delivering a distinguished tactile response.

Program with QMK & VIA.

QMK/VIA means endless possibilities for a fluid workflow. Thanks to our engineering team, it's the first time in history that a wireless mechanical keyboard has these kinds of capabilities right out of the box.

Simply connect the K3 Pro to your device with a cable, drag and drop your favorite keys or macro commands to remap any key you want on any system (macOS, Windows, or Linux). 

Check out the video above demonstrating how to remap the Light Effect key (located on the K3 Pro’s top right corner) to an Eject key with the VIA software, so you can get a shortcut to put your Mac to sleep (Command-Option-Eject), or even remap the fn key in a breeze. It’s never been so intuitive and flexible to personalize your own keymap.

An ultra-low-power ARM Cortex-M4 32-bit STM32L432 MCU which is powerful, and equipped with 128K Flash will provide more flexibility for developers.

Get the keymap working on VIA

Since the VIA code for the K3 Pro is still awaiting approval from Github, it is not yet automatically recognized, so you will need to manually download and import the K3 Pro keymap.

Please download the keymap JSON file below. Connect your keyboard and device with the provided cable, and toggle the switch to cable mode. Open VIA, click on the "Show Design tab" on the "Settings" tab, enable "Use V2 definitions (deprecated)" on the "Design" tab, and drag the JSON file into the “Design” tab on VIA to get the K3 Pro keymap working on VIA.

Suitable For All Devices

Offers a Mac layout while still being compatible with Windows, the K3 Pro is one of the few on the market that has the same multimedia and function key functions as Apple keyboards for Mac users, but with more tactile feedback.

You can even configure different keymaps for both Mac and Windows devices. While VIA software is compatible with macOS, Windows, and Linux. Includes keycaps for both macOS and Windows (and additional esc and enter keys) to allow you to switch between operating systems with ease.

An Epic Core Inside

A powerful ultra-low-power ARM architecture MCU equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz on wired mode, which makes latency non-existent for the competitive game.

Hot-swappable

We all have our unique typing preferences, that’s why we are offering hot-swappable option on the K3 Pro, so you can easily hot-swap every low-profile Gateron mechanical switch in a few seconds to customize the typing experience without soldering.

*The K3 Pro is currently compatible with Gateron low-profile mechanical switches only, as QMK does NOT support low-profile optical switches.

Low-Profile Gateron Switch

The Gateron low-profile MX Mechanical switch is designed to enhance reliability. Gateron's reputable switches are your best choice for a precise, smooth, and reliable fingertip feel whether you prefer linear (red), clicky (blue), or something in between (brown).

Keychron's regular K3 was my first mechanical keyboard, which I bought a little over two years ago now. I really liked the compact form factor and the low-profile switches, which are a must for me if I want to be able to type quickly and accurately. However, there were downsides to the keyboard. Although the aluminum base felt sturdy and had a high-quality feel, the contact points (i.e., the keys) did not. Moreover, for reasons that are not quite clear to me, I found myself having more typing errors with the chicklet-style keycaps. Thus, I set aside my normal K3 and ventured on to other models from Drop and Ducky, just to name a few.

One day, Google happened to recommend to me an article about a new K3 Pro keyboard Keychron was releasing through Kickstarter. As soon as I saw the changes from the original model, I strongly suspected this would easily place as my new favorite. I was not wrong.

The keycaps are much improved, it sounds great (to my admittedly novice ears), and I really like the eye-catching-yet-understated keycap colors, which are perfect for my office. I know it has other features, which I frankly don't use. To me, it was well worth the money (and Kickstarter wait-times) to upgrade from the original K3, which has been relegated to my laptop bag for occasional use out of the office. Total home run in my book. (I will note that Jordan is correct that the RGB does not really shine through the keycaps, but, again, it provides just enough flair without being gaudy in my office, so that is not a problem for me.)

I have not bought a Keytron product before and the K3 is amazing! I love this keyboard. It connects to all my devices and the switches feel great typing on them. They are not loud like the traditional clicky sound you get from a mechanical so it is okay to use in an office setting. I use the keyboard on both Windows and Mac with no issues. If you are planning to travel with the keyboard I recommend get the travel case as the keyboard fits snug and will protect the keyboard from scratching when traveling with it. Also, keep in mind this keyboard is very small too. The images do not do justice on how small this keyboard is. If you do not like compact this one is not for you but if you want a small keyboard to travel or just like the small footprint then this is perfect for you. The colors are great and the red enter key and esc key make a good contrast as well. I have the RGB option and it comes with a lot of color variations and color sequences too. This is a cool feature to have but does not make or break the device for me.
