Keychron K5 SE Features

Keychron K5 SE has the following features

  • Low-profile switches that are 40% slimmer than normal profiles
  • Robust with aluminum frame
  • Bluetooth 5.1 support allows switching between up to three devices.
  • Mac/Windows compatible
  • 6°/9° tilt leg support
  • full-size keyboard
  • Hot-swappable models available

The most distinctive feature is the use of low-profile switches and full-size switches.

Until then, the Keychron K1V4 was a full-size keyboard with low-profile switches, but it is now obsolete and has disadvantages such as no tilt leg and special keycap shape.

The Keychron K5 SE successfully eliminates this disadvantage.

Differences between Keychron K5 and K5 SE

A similar model is the Keychron K5.

Let’s look at the detailed differences.

With the “SE” in its name, the Keychron K5 SE can be positioned as a lower-priced version of the Keychron K5.

If you are looking for a better key feel, the K5, with its full aluminum body, is the better choice.

On the other hand, the K5 SE comes with a tilt leg, which may be better in terms of ease of typing.

As for the Keychron K5 SE, it is also nice to know that you can choose not only the US layout but also the JIS (Japanese) layout.

Keychron Optical Switch is not an option for K5 SE at authorized distributors in Japan.

Unfortunately, no Keychron optical low-profile mechanical switch models were available from Kopec Japan.

Personally, I am a bit disappointed, partly because I like the Keychron Optical switch.

The Gateron Lowprofile keyswitch is light compared to the specs in terms of pressing pressure, and even in the case of the 55gf brown axis, it feels only about 45gf in weight to the senses.

In addition, the keyswitches are slow to return after being pressed, giving the impression that it is difficult to type smoothly.

Furthermore, there are only three types of switches to choose from, which limits the range of options.

On the other hand, the keychron optical switches have a slightly lighter feel than the published values, but no matter which switch is selected, the return after pressing is so smooth that the keys feel the same as normal profile key switches.

The authorized domestic sales model that uses the Keychron Optical switch is the Keychron K5.

The K5 SE is a full aluminum body and not much more expensive than the K5 SE, so if you are looking for a good typing experience, we recommend buying the K5 rather than the K5 SE.

However, the only pre-set axes are the “blue, brown, and red axes,” so to use other key switches of your choice, you will need to purchase them separately.

Also, please note that the K5 has a “US only” layout.

I recommend the “banana axis” and “mint axis” with their early bumpiness!

Summary|Low-profile keyboards are about to become popular.

These are the topics that we have reported about Keychron K5 SE being officially sold in Japan.

Recently, low-profile mechanical keyboards have gradually entered the keyboard market, with the MX MECHANICAL, a similar full-size keyboard, increasingly being discussed.

The “good parts” of the keyboard are probably its appeal, with a solid key feel inherited from the normal profile and a thin, lightweight design that is as thin as a pantograph keyboard.

If this is your preference, you should consider using this service.
