SP-Star RedBlue vs. KTT Semi Mute
An in-depth look at the SP-Star RedBlue and the KTT Semi Mute switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, two popular options that cater to different preferences are the SP-Star RedBlue and the KTT Semi Mute. The RedBlue switches are known for their medium-light typing experience and a relatively higher-pitched sound profile. They are perfect for those who enjoy a polished and thocky typing feel. On the other hand, the Semi Mute switches, despite their name, offer completely silent operation, making them ideal for individuals who prioritize a noise-free environment. With a linear actuation and advanced dampening technology, these switches provide a buttery and muted typing experience. Both switches have their unique qualities and desirable features, making them suitable for different user preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the SP-Star RedBlue and the KTT Semi Mute, specifically their polycarbonate top and bottom housings, are virtually identical. In both switches, the use of polycarbonate creates a sharper, higher-pitched, and crisper sound profile. This is because polycarbonate is a stiff plastic that allows for clear and resonant sounds. Additionally, both switches feature a clear housing, which is a clear indication that polycarbonate is likely to be the material used. The translucency of polycarbonate is especially advantageous for those planning to use RGB lighting as it allows for the illumination to shine through effectively.
However, it is worth mentioning that if the top and bottom housings differ in a particular switch, the qualities attributed to each housing material will be split accordingly. When you press down on the switch, the bottom housing has a more significant impact on the bottom-out sound and feel. Conversely, the top housing influences the sound when releasing a key. This distinction may result in a slight variation in the overall sound experience between the RedBlue and the Semi Mute, depending on the specific design and composition of their housing materials.
Despite any minute differences, it can be inferred that the overall performance and characteristics of the housing materials in both switches will be fairly similar. Since the properties and benefits of polycarbonate, such as its stiffness and ability to transmit clear sounds, are described in the same manner for both switches, users can expect a comparable auditory experience from the RedBlue and the Semi Mute. Whether typing or gaming, both switches are likely to provide a pleasant and responsive sound profile due to the utilization of polycarbonate in their housing materials.
Weight
When comparing the actuation force and bottom out force of the SP-Star RedBlue linear switch and the KTT Semi Mute linear switch, there are some notable differences. The RedBlue has an unknown actuation force, while the Semi Mute has an actuation force of 43 grams. This means that the Semi Mute requires a lighter force to initiate a keystroke compared to the RedBlue. Moving on to the bottom out force, the RedBlue has a bottom out force of 57 grams, which is considered medium-light, while the Semi Mute has a slightly heavier bottom out force of 58 grams, which is also classified as medium.
Considering the importance of weight in keyboard preferences, those who prefer a lighter typing experience may lean towards the Semi Mute switch due to its lower actuation force. This lighter actuation force allows for longer periods of comfortable typing, making it ideal for everyday use or extended gaming sessions. On the other hand, individuals who prefer a more substantial and satisfying typing feel may gravitate towards the RedBlue switch. While the actuation force of the RedBlue is unknown, the heavier bottom out force of 57 grams provides a stronger push feel, offering a more robust typing experience.
In summary, the SP-Star RedBlue linear switch and the KTT Semi Mute linear switch differ in their actuation and bottom out forces. The Semi Mute has a lighter actuation force, making it suitable for those seeking a lighter typing experience, while the RedBlue offers a heavier bottom out force for users who prefer a more substantial and satisfying feel while typing.
Travel distance
The travel distance of a switch is an important factor to consider when choosing a keyboard. In the case of the SP-Star RedBlue linear switch and the KTT Semi Mute linear switch, both switches have a travel distance of 4 mm. This means that when you press down on a key using either switch, you will feel the same distance being traveled from the top to the bottom. Therefore, if you are looking for a keyboard with a specific travel distance in mind, both the RedBlue and the Semi Mute will provide you with similar results. It is worth noting that having the same travel distance does not necessarily mean that these switches will feel identical, as there may be other factors such as actuation force or keycap material that can affect the overall typing experience.

Typing experience
When it comes to sound, the SP-Star RedBlue linear switch is best described as having a relatively higher-pitched sound profile. This means that the switches produce a slightly higher tone when pressed, giving a more lively and energetic typing experience. On the other hand, the KTT Semi Mute linear switch is known for its muted sound. Despite being completely silent, these switches are specifically designed to minimize noise and create a quieter typing environment. While the RedBlue offers a more lively and energetic sound, the Semi Mute provides a more subdued and noise-free typing experience.
In terms of feel, the SP-Star RedBlue linear switch is characterized as providing a mild typing experience. This means that the switches offer a gentle and approachable feel to most typists, without any extreme characteristics or overwhelming features. Additionally, the RedBlue switches have a polished finish, which results in a sleek and refined typing experience. The polished surface reduces friction and ensures smooth key travel. On the other hand, the KTT Semi Mute linear switch offers a buttery feel. This implies a smooth and fluid keystroke experience, providing a seamless and effortless typing sensation. Similar to the RedBlue, the Semi Mute also provides a mild typing experience, ensuring comfort and accessibility for most users.
Taking all the available information into consideration, the SP-Star RedBlue linear switch is best suited for those who prefer a medium-light typing experience, with a relatively higher-pitched sound profile and a mild and polished feel. On the other hand, the KTT Semi Mute linear switch is tailor-made for individuals who value a noise-free environment and desire undisturbed typing, especially during late-night sessions. It offers a muted sound profile and a buttery, mild typing experience. Both switches provide a neutral actuation force requirement and can be suitable for users at any experience level and for various settings. However, it's important to note that the sound and feel of the switches can also be influenced by other factors such as the choice of keyboard board and keycaps. Therefore, while the SP-Star RedBlue and KTT Semi Mute switches differ in their subjective qualities, using either switch will yield comparable results in terms of sound and feel.
Conclusion
In closing, if you value a medium-light typing experience and a relatively higher-pitched sound profile, the SP-Star RedBlue linear switch is the perfect choice for you. These switches offer a gentle and polished typing experience, with reduced friction and smooth key travel. On the other hand, if you prioritize a noise-free environment and undisturbed typing, particularly during late-night sessions, the KTT Semi Mute linear switch is the ideal option. These switches provide a comfortable and gratifying typing feel, with their advanced dampening technology and completely silent operation. They offer a muted sound profile and a buttery, seamless typing sensation. Ultimately, the decision between the two switches depends on your personal preferences and the specific typing experience you are looking for.
