What is the Keychron K6 Wireless Mechanical Keyboard?

The Keychron K6 is a compact wireless mechanical keyboard designed and manufactured by Keychron, a company known for producing high-quality mechanical keyboards on the market. The keyboard is optimized for both Mac and Windows users.

The Keychron K6 is a compact, customizable 65 percent keyboard that's packed with features and offers both wired and wireless connections. This means it is smaller than a full-sized keyboard while still retaining essential keys such as the arrow keys and some function keys.

Like many compact keyboards, the Keychron K6 does not have a numeric keypad. 

Technical Specifications and Features of the K6

The technical aspects of the Keychron K6 are packed with impressive specs that'll surely catch your attention.

  1. Form Factor: Compact 65% layout, which includes essential keys such as alphanumeric keys, arrow keys, and some function keys.
  2. Switch Options: The Keychron K6 keyboard comes with a variety of switch options, including mechanical switches like Gateron, hot swappable switches, or optical switches. You can choose linear switches, tactile switches, or clicky switches. The specific switch options may vary by model. 
  3. Connectivity:
    • Wireless Bluetooth 5.1 connectivity, allowing you to pair the keyboard with up to 3 devices.
    • Wired USB-C connectivity for a stable wired connection.
  4. Battery: A built-in rechargeable battery with a 4000 mAh battery, which can last up to 4 weeks after a single charge if you're not using the backlighting. That's one long battery life!
  5. Backlighting: RGB lighting with 18 different, customizable lighting effects and colors. Some versions of the K6 may offer single-color backlighting options. 
  6. Compatibility: The Keychron K6 keyboard is designed for both Mac and Windows users with switchable layouts. Simply slide the button on one side of the keyboard when used with an Apple or Windows computer. You can connect your keyboard to a Windows PC and then swap to an Apple iPad when used in conjunction with its Bluetooth functionality.
  7. Keycap material: Keycaps are often made of ABS or PBT plastic, and the keycap profile may vary (e.g., OEM, DSA, or SA profile).
  8. Construction: The build quality of the K6 is excellent. The keyboard's frame and case may be made of aluminum or plastic, depending on the specific model. The aluminum case is pricier, but is sturdy and gives the keyboard a more solid feel. The plastic base is lighter, making it a perfect on-the-go peripheral.
  9. Customization software: Some versions of the Keychron K6 come with software that allows you to customize key functions, macros, and lighting effects.

Optical/Hotswappable Switches

One of the key features you'll appreciate about the Keychron K6 is its hot-swappable switches. This feature allows you to change switches without needing to solder. This gives you the freedom to find your perfect switches without going through the hassle of soldering and desoldering.

The K6 supports all MX style 3-pin and 5-pin mechanical switches. So, whether you're a fan of Cherry MX, Kailh, or Gateron switches, you're covered.

The K6 also offers the option of optical switches. These switches use light for actuation, making them faster and more durable than their mechanical counterparts. If you're part of the gaming community, this can give you the edge you need.

Other Features

Those are just the key features of the Keychron K6. With the inclusion of these other features, the Keychron K6 is a computer peripheral that is highly recommended by keyboard enthusiasts.

1. Detachable USB C Cable: The inclusion of the USB-C cable allows you to connect the keyboard to other devices. Wireless devices improve mobility, reduce messy cable tangles, and make these devices portable. But there are times and scenarios where a cabled connection is preferred. For example, you may be using the keyboard to play a fast-paced game. You don't want to ruin your competitive edge by latency disruptions. The USB-C cable is detachable and reversible. 

2. Adjustable rubber feet: These rubber feet can be inclined by 6 degrees. This allows users to change the typing angle for ergonomic comfort.

3. Multimedia keys: Multimedia keys allow you to control media functions such as volume, video/music scrolling, brightness, etc. directly on the keyboard.

4. Keycap puller: When you purchase a Keychron K8, it usually comes with a keycap puller. This allows you to quickly, safely, and easily keycaps if you want to customize your keyboard.  

Drawbacks of the Keychron K6

The Keychron K6 is generally well-regarded, but like any product, it may have some drawbacks or limitations. 

  1. Compact layout: While the compact 65% layout of the K6 can be a benefit for portability and desk space, it may not be suitable for users who rely heavily on a dedicated number pad or function keys. Users who require a full-sized layout might find the K6 less convenient for tasks like data entry.
  2. Bluetooth connectivity stability: Some users have reported occasional issues with Bluetooth connectivity, such as occasional disconnects or latency. The stability of Bluetooth connections can depend on factors like the quality of the Bluetooth adapter in your device and potential interference from other devices.
  3. Keycap quality: Keychron K6 keyboards may come with keycaps made of ABS plastic, which can be less durable and more prone to shine or wear over time compared to PBT keycaps. However, some versions of the K6 offer PBT keycaps as an option.
  4. Keycap legends: The legends (letters and symbols) on the keycaps may wear off over time with heavy use. This is a common issue with many keycap sets, but it's worth noting.
  5. Battery life: While the K6 typically offers decent battery life, it can vary depending on usage and lighting settings. Users who prefer extended periods between charges may need to reduce the use of RGB backlighting.
  6. Customization learning curve: While the K6 offers customization options through software, some users may find the customization process a bit complex or time-consuming if they are new to mechanical keyboards.
  7. Lack of dedicated function row: The 65% layout of the K6 means it doesn't have a dedicated function row (F1 to F12), which may be a drawback for users who rely on these keys for specific functions or shortcuts.
  8. Price point: The Keychron K6 is positioned as a premium mechanical keyboard, and its price point can be relatively higher compared to some other mechanical keyboards with similar features. However, it's worth considering whether the features and build quality justify the price for your specific needs.

Sound Tests

The K6 emits a satisfying click with every keystroke, making typing a pleasure. The sound is crisp and clear, without the excessive clatter found in some mechanical keyboards. It's a sound that fits comfortably in a busy office or a quiet home setup, without disturbing others around you.

If you're someone who enjoys the auditory feedback of your typing, you'll appreciate the K6. However, as with everything in the tech world, sound can be subjective. What sounds like music to your ears might be noise to another.

In such a case, you may want to change the clicky or tactile switches to linear or Red switches for a quieter experience.

Scaling Price Options

The price of the Keychron K6 scales is based on the customization options you choose. The K6 is a mid-range to premium keyboard. The base model is priced at $69 to 90. But as you add features like the sturdy aluminum frame or the hot-swappable PCB, the price increases. 

The most expensive option is the one with full RGB lighting, aluminum case, and hot-swap sockets. If all these extra features are not required, you can just opt for a plastic case with a white backlight and normal PCB for a significantly lower price.

Possible Customer Complaints

While there's a lot to love about the Keychron K6, you might encounter a few potential issues worth noting.

Customers often raise complaints about the overall height of the keyboard. Some users find it too high, causing discomfort in the wrist area. This can be easily remedied by using a wrist rest. 

The keycaps on the base keyboard from thin ABS plastic, which some find low-contrast. Over time, the legends (letters and symbols) on the keycaps may wear off or fade with heavy use. This is a common issue with keycap sets made of ABS plastic.

Non-uniform keycap profiles mean some keys don't align properly.

Lastly, some users found the Keychron software for customizing key functions and macros to be less user-friendly or intuitive. Customization can be a bit complex for those new to mechanical keyboards.

If you run into any issues, don't hesitate to reach out to Keychron for more information and support.
