An ode to the Keychron K4

Take a seat

Normally, we use this section of text to write something fun and light-hearted about a product. However, I now want to use it to make sure you grab a cup of coffee or tea before you start reading, because there's quite a bit to tell about the K4. Are you settled? Perhaps a biscuit too? Let’s go!

Why the Keychron K4 keyboard?

Very complete

The Keychron K4 gives you all the keys a keyboard can have and uses 96% of the usual space for this. This means the keyboard is narrower for ergonomic reasons. Furthermore, it has hotkeys that can be used by pressing combination keys.

The K4's connectivity is fantastic. Via Bluetooth, you can wirelessly connect up to three devices to the keyboard simultaneously. Using combination keys, you can quickly and easily switch between your devices. For example, one moment you might be working on your laptop, and the next you're quickly typing a WhatsApp message about dinner. A fourth device can be connected with a cable (USB). Of course, connecting a single device and using the USB cable for that is also an option.

Matching K4 wrist rest

Keychron has designed two wrist rests specifically for the K4. One is made of American walnut wood. The other combines this same wood with resin for a unique look. Furthermore, the keyboards feature 4 anti-slip points that ensure the wrist rests stay in place.

Thanks to the support, your wrists and hands are at the correct height for using the keyboard. This optimises relaxation and prevents injuries. You can add the wrist rests to your order at the top right of the page. You can read more about the wooden wrist rest here. And here you can read more about the resin wrist rest.

PLEASE NOTE: Keychron wrist rests are natural products and therefore never identical. The product received may therefore differ from the photo.

Carrying case

The Keychron carrying case is the optimal way to transport your Keychron keyboard. The case opens and closes with a zip and consists of a compartment for the keyboard and a compartment for the cable inside. The case is made of plastic and canvas, providing a combination of durability, sturdiness, lightness, and style. The rubber handle makes carrying easy. You can find more information about the case here. You can add it to your order at the top right of the page.

Gateron switch puller

The Gateron switch puller is the ultimate addition to your hot-swappable keyboard. Our hot-swappable keyboards already come standard with a keycap and switch puller. However, this switch puller is more user-friendly.

Place the Gateron switch puller over the switch and press down until you hear a click. Now you can easily pull out the switch. With a press of the button at the top, the puller releases the switch. You can read more about the Gateron switch puller here.

What makes an ergonomic keyboard so good?

Anyone who performs a lot of computer work knows that this can be strenuous for your wrists, shoulders, back, and neck. A good keyboard can help you with this. The Keychron K4, for example, has a compact design. The keys are also extra easy to press. Furthermore, you can place your mouse close to the keyboard. All of this is to minimise muscle tension, thereby preventing or reducing injuries.

Get the most out of this product

The K4 uses Gateron mechanical switches. You have a choice of Red, Brown, and Blue switches. You can also opt for Hot-Swappable keys. In this overview, you can find the characteristics of these keys.

The K4 can be updated to remove any production and/or design flaws. Therefore, regularly check this Keychron page to see if updates are available. Please note: Read the instructions on this page carefully, as downloading the wrong firmware can be fatal for the keyboard.

Don't miss this either

The Keychron K4 features a powerful 4000mAh battery that lasts up to 72 hours with normal use. The keyboard also has backlighting, making the keys clearly visible in dimly lit areas. The RGB backlighting gives you access to 18 different colour effects with four brightness levels.

The Keychron K4 is suitable for both Windows and Mac. A slider switch on the side allows you to easily switch between operating systems. System-related keycaps are included and can be easily swapped by yourself.
