MTNU (which stands for 'MT Numeric') has been known for its unique approach to keycap design, and the OS2.0 iteration aims to refine the formula. With a focus on comfort and sound, these keycaps are generating buzz in the community. Let's see if they live up to the hype.

Design and Build Quality

The MTNU 800 OS2.0 keycaps feature a sculpted profile that is slightly taller than Cherry but lower than SA. The keycaps are made from durable PBT plastic with a thick wall construction, ensuring they can withstand heavy use without developing a shiny finish. The legends are crisp and sharp, thanks to the double-shot molding process, which also guarantees the legends never fade.

One of the standout design elements is the new OS2.0 colorway, which combines a deep navy blue with vibrant accents. The set includes compatibility for a wide range of layouts, including TKL, 60%, and 65%, making it versatile for different keyboard builds. The keycaps have a subtle texture that provides a good grip without being too rough.

  • Double-shot PBT for durability and fade-resistant legends
  • Sculpted profile with a comfortable height
  • Compatible with standard MX-style switches

Typing Feel and Ergonomics

Typing on the MTNU 800 OS2.0 is a pleasant experience. The sculpted profile offers a natural finger movement, reducing strain during long typing sessions. The keycaps have a slight dish on the top, which helps guide your fingers to the center, improving accuracy. The transition between rows is smooth, making it easy to touch-type without hitting the edges of adjacent keys.

The keycaps are designed to sit comfortably on the switches, with a snug fit that prevents wobble. The height is well-balanced, providing a good angle for ergonomic typing. Whether you're a gamer or a writer, these keycaps are likely to feel comfortable and responsive.

Sound Profile

Sound is a major consideration for many enthusiasts, and the MTNU 800 OS2.0 delivers a satisfying thock. The thick PBT material and the sculpted design contribute to a deeper, more muted sound compared to thinner keycaps. This is especially noticeable on boards with a gasket mount or foam, where the sound becomes even more refined.

If you're using linear switches, the sound is clean and consistent, while tactile switches add a slight pop. The keycaps also do a good job of reducing the hollowness that can occur with some profiles, making them a great choice for those who prefer a quieter setup.

Compatibility and Installation

The MTNU 800 OS2.0 keycap set is designed to fit most mechanical keyboards with standard MX-style switches. The set includes all the keycaps you need for a TKL layout, plus extras for 60% and 65% boards. The spacebar is 6.25u, which is standard for most keyboards, but if you have a board with a 7u spacebar, you might need to look elsewhere.

Installation is straightforward: simply remove your old keycaps and press the new ones onto the switches. The keycaps fit snugly and don't require any additional tools. If you're using a keyboard with a non-standard bottom row, be sure to check the layout compatibility before purchasing.

  • Includes keys for TKL, 60%, and 65% layouts
  • Standard 6.25u spacebar
  • Fits Cherry MX and clones

Comparison with Other Keycap Profiles

When compared to other popular profiles like Cherry, OEM, and SA, the MTNU 800 OS2.0 offers a unique middle ground. It's taller than Cherry and OEM, but shorter than SA, giving it a distinctive feel that some users may prefer. The sculpting is more pronounced than Cherry, which can help with typing ergonomics.

In terms of sound, the MTNU profile tends to be deeper than Cherry, but not as loud as SA. This makes it a versatile choice for those who want a balance between the two. If you're coming from a uniform profile like XDA, the MTNU will feel quite different, but many find the transition to be a positive one.

The MTNU 800 OS2.0 keycaps are a fantastic addition to the world of keycap profiles. With their excellent build quality, comfortable typing feel, and satisfying sound, they offer a compelling option for both enthusiasts and newcomers alike. If you're looking to upgrade your keyboard's look and feel, these keycaps are definitely worth considering.
