K1 – Tenkeyless

The K1 keyboard has a few options to choose from. For example, you could get it as a full size or as a tenkeyless keyboard. The smaller keyboard, of course, comes at a cheaper price.

You also get two choices of key switches. You can choose from the Gateron low profile reds or the low profile blues. Reds being linear and blues being clicky.

You also get the choice of backlighting. You can either get the full RGB with 17 different settings, or a simple white backlight if you want to save some money.

Also, you can use this keyboard either with a wired connection or completely wireless via Bluetooth.

Whichever choices you make it doesn’t affect the performance of the keyboard. Those are really just personal preference items.

Some people like smaller keyboards and don’t care about RGB, while others have to have a full-size keyboard with RGB. But these characteristics don’t make the keyboard better or worse.

The K1 also offers full support for Mac and Windows, so it doesn’t matter which operating system you plan to use your keyboard with. It should work perfectly fine on either one.

This keyboard looks great overall and the only downside is the low profile keys. The keyboard sort of feels like a laptop when typing on it. Your fingers could start to hurt over time from the constant typing and bottoming out.

K2 – 75 Percent

The K2 is a 75% keyboard which is a bit smaller than the K1. The keys are also a bit closer together which may make it harder to type if you have fat fingers. Like the TKL, there is no numpad and the home cluster has been reduced.

This keyboard is a wireless mechanical keyboard with a great battery that can last up to two weeks. You could plug it in while you use it though it may be a bit awkward as the USB-C cable plugs in on the left side.

Since we’re talking about negative things, I should also mention the thickness of this keyboard. You really don’t want to use it without a wrist rest as it may cause an uncomfortable bending of your wrist which may start to hurt after a while of use.

However, don’t let those couple of negatives turn you off from this keyboard. It is still a great one to have. this keyboard can connect to three devices at once making it super easy to move from room to room and device-to-device.

It also has a toggle switch to switch between using it for a Mac and using it for a Windows PC. this means you will have no problems using this keyboard no matter which operating system you prefer

K4 – 1800 Compact

The K4 offers a very unique style keyboard known as the 96% or the 1800. It’s pretty hard to find this style keyboard. The home cluster is arranged in a horizontal row rather than a three-by-three grid. It’s also a bit more compact than a standard keyboard.

This keyboard also offers quite a bit of customization options like the K2. Though, You do have a few more switch options in this one. You have the same red and blue options as the K2 however you can also opt-in for the yellow or brown switches if you prefer.

Much like the previous model, you may want to get a wrist rest with this one as well. It may be a bit thinner than the other model however it’s thicker towards the front causing your wrist to bend just a bit. I think the best way to balance that out would be with a wrist rest.

The other similarity to the other model is that it is wireless and it is also compatible with both Mac and windows. It also offers RGB lighting.

K6 – 65 Percent

Finally, we have the K6. this one is my personal favorite as it has the most features and I also love the 65% layout which is what this one is.

The 65 is very compact removing the Numpad and top function row. Though it still has the dedicated arrow keys which is a must have for me and most people as well.

The K6 has similar features as the K2 and k4 with a few other options. You can choose if you want a more heavy-duty aluminum case for a bit extra, or go the cheaper route with a plastic case.

The aluminum case will, of course, make the keyboard last longer but it may be annoying to travel with or move it around as it’s a bit heavier. However, if you plan to keep the keyboard pretty stationery then the aluminum might be a good choice.

This is the only Keychron model that has the option of being hot-swappable. This is an amazing feature and makes it super easy to replace broken keys or remove them for lubing without the need to desolder.

This is the newest keyboard and honestly, if you’re going to go with a Keychron I would go with this one. Make sure to look at 65% keyboards and make sure that the layout is something you will be comfortable with.
