Typing Experience: Low-Profile Mechanical Bliss

The core of any mechanical keyboard review boils down to the typing experience, and the Cooler Master SK622, with its low-profile Cherry MX mechanical switches, delivers a surprisingly robust and satisfying performance. This isn’t just about compact design. it’s about translating the beloved mechanical feel into a sleeker, more portable form factor.

Cherry MX Low Profile Switches

Cooler Master has partnered with Cherry, a titan in the mechanical switch industry, to integrate their low-profile switches into the SK622. This is a crucial distinction from traditional mechanical keyboards.

Reduced Height: These switches are significantly shorter than their full-height counterparts, allowing for the keyboard’s slim profile.
Actuation Point: Typically, low-profile switches have a shorter actuation distance e.g., 1.2mm for Reds, 1.3mm for Browns compared to standard switches 2.0mm. This means your keystrokes register faster, which can be advantageous for gaming or rapid typing.
Total Travel: The total travel distance is also reduced e.g., 3.2mm for Reds/Browns vs. 4.0mm for standard. This contributes to the “snappier” feel.
Available Variants: The SK622 is commonly available with:
- Cherry MX Low Profile Red: Linear, smooth, and quiet. Ideal for gaming due to their light actuation force and rapid response.
- Cherry MX Low Profile Brown: Tactile, offering a subtle bump during actuation. A popular choice for a balance of typing and gaming, providing feedback without being overly loud.
- Cherry MX Low Profile Blue: Clicky, with a distinct audible click and tactile bump. Favored by typists who enjoy strong feedback. Less common in the SK622 lineup but worth noting for Cherry LP.

Key Feel and Sound Profile

Despite their reduced travel, the Cherry MX Low Profile switches largely retain the characteristic feel of their full-sized brethren.

Tactile Feedback Browns: If you opt for the Low Profile Browns, you’ll experience a gentle, yet discernible bump. This tactile feedback is invaluable for accurate typing, helping you know exactly when a key has registered without “bottoming out” forcefully.
Linear Smoothness Reds: The Low Profile Reds offer a buttery-smooth press from top to bottom, making them excellent for quick, repetitive presses in games.
Sound Profile: Due to the shorter travel and lower profile, the sound is generally less pronounced than full-sized mechanical keyboards.
- Browns: Produce a soft “thock” or “clack” depending on your typing force and the desk surface. They are generally quieter than traditional Browns.
- Reds: Are very quiet, primarily producing the sound of the keycap hitting the switch housing, or bottoming out on the PCB.
Stabilizers: Cooler Master employs plate-mounted stabilizers for larger keys like the spacebar, shift, and enter. These are decent, providing a relatively stable key press without excessive wobble. Some users might find a slight rattle, but it’s generally within acceptable limits for a mass-produced keyboard at this price point. Enthusiasts might consider lubricating them for an even smoother experience, but for most users, they perform admirably out of the box.

Adaptation Period

Transitioning from a full-sized or even a traditional TKL mechanical keyboard to the SK622’s low-profile, 60% layout requires a short adaptation period.

Keycap Profile: The flat, chiclet-style keycaps are quite different from sculpted keycaps found on many mechanical keyboards. Your fingers might take a moment to get used to the flatter surface.
Reduced Key Travel: The shorter travel distance of the switches means less finger movement is required. This can initially lead to accidental presses until your muscle memory adjusts. However, once accustomed, many find it leads to faster and less fatiguing typing over long periods.
Function Layer Reliance: The absence of dedicated function rows and navigation keys means frequent use of the “Fn” key in combination with other keys. Cooler Master does a good job with printed legends for these functions, but it still requires learning the specific combinations. For example, Fn + I/J/K/L might be your arrow keys.

Overall, the typing experience on the Cooler Master SK622 is a pleasant surprise.

It manages to retain the essential qualities of mechanical switches – distinct actuation and durability – while embracing a low-profile design.

For those who prioritize portability and a sleek aesthetic without giving up on mechanical feedback, the SK622 is a highly commendable performer.
