SP-Star RedBlue vs. Kailh Sage
An in-depth look at the SP-Star RedBlue and the Kailh Sage switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, two popular choices to consider are the SP-Star RedBlue and the Kailh Sage. The RedBlue is a linear switch, while the Sage is a clicky switch. Each switch offers a unique typing experience that caters to different preferences. The RedBlue is best known for its medium-light typing experience and higher-pitched sound profile. It falls under the categories of low-pitched, neutral, mild, thocky, and polished. On the other hand, the Sage is recognized for its distinct clicky typing experience, with a heavy weight and refreshingly sharp clickiness. It is categorized as invigorating, sharp, and crunchy. Choosing between these switches ultimately depends on individual preferences and typing style. However, let's dive deeper beyond these generalities so you can make an informed decision on the best switch for you.

Housing materials
The SP-Star RedBlue and the Kailh Sage both feature polycarbonate top housings, which contribute to a sharper, higher-pitched, and crisper sound profile. This is because polycarbonate is a relatively stiff plastic, resulting in a more clear and resonant sound. Aesthetically, the translucent nature of polycarbonate is particularly useful for switches that utilize RGB lighting. In terms of sound, both switches offer similar qualities due to their shared polycarbonate top housing material, resulting in a satisfying typing experience.
However, the bottom housings of these switches differ. The RedBlue utilizes polycarbonate for its bottom housing, while the Sage utilizes nylon. Typing on the RedBlue with its polycarbonate bottom housing creates a sharper and more resonant sound. In contrast, the Sage with its nylon bottom housing elicits a deeper and fuller sound profile. This is because nylon is a softer plastic that absorbs more sound, resulting in a duller and rounder sound. Therefore, the bottom housing in these switches plays a significant role in determining the bottom-out sound and feel.
When it comes to the top housing's impact on the sound, both the RedBlue and the Sage share similar characteristics due to their polycarbonate top housing material. Pressing down on either switch will allow you to feel the qualities of the bottom housing, while the sound when releasing a key will primarily be influenced by the top housing. Therefore, while the bottom housings differ, the shared polycarbonate top housing material ensures a comparable sound experience when using either the RedBlue or the Sage switches.
Weight
When comparing the actuation force and bottom out force of the SP-Star RedBlue linear switch and the Kailh Sage clicky switch, it is clear that both switches have an unknown actuation force. This means that obtaining similar results in terms of the force required to trigger a keystroke can be expected from both switches. However, in terms of bottom out force, there is a noticeable difference.
The RedBlue has a bottom out force of 57 grams, which falls within the medium-light range. This lighter force may be preferred by individuals who value a keyboard that allows for longer typing sessions, making it ideal for work or extended gaming sessions. On the other hand, the Sage clicky switch has a bottom out force of 70 grams, which is considered medium-heavy. This heavier force provides a more substantial typing experience for individuals who prefer a stronger push feel.
Considering weight is important for various reasons, and it ultimately depends on personal preferences. For those who enjoy lighter switches, the RedBlue would be a suitable choice, allowing for extended periods of typing without fatigue. However, if a more substantial typing experience is desired, the Sage clicky switch, with its heavier bottom out force, would be the preferred option.
Travel distance
Compared to the Kailh Sage clicky switch with a travel distance of 3.6 mm, the SP-Star RedBlue linear switch has a slightly longer travel distance of 4 mm. The RedBlue's travel distance of 4 mm falls into the category of a more traditional travel distance, while the 3.6 mm travel distance of the Sage is considered slightly shallower. Despite the difference in travel distance, both switches offer a satisfying key press experience. Gamers, in particular, often prefer shorter travel distances for faster response times, making the Sage a potential favorite for them. On the other hand, individuals who enjoy a deeper and more substantial key press may find the RedBlue's longer travel distance more to their liking. Ultimately, the choice between the two switches comes down to personal preference and the desired balance between responsiveness and depth.

On the other hand, the Kailh Sage clicky switch offers a distinct clicky typing experience. It is known for its heavy weight and refreshing sharp clickiness. The Sage switch produces a crunchy sound, reminiscent of stepping on piles of crisp and autumn leaves. In terms of feel, it provides an invigorating typing sensation with pronounced feedback, moderate to firm actuation force, and a snappy and reactive feel. The Sage clicky switch also has a sharp tactile bump that can be felt distinctly with each keypress.
In conclusion, both the SP-Star RedBlue linear switch and the Kailh Sage clicky switch offer unique qualities. The RedBlue linear switch provides a medium-light typing experience with a higher-pitched and thocky sound profile. It offers a mild and polished feel, suitable for most users. On the other hand, the Sage clicky switch offers a distinct clicky typing experience with a heavy weight and sharp clickiness. It provides an invigorating and sharp tactile feel. While the sound and feel of each switch differ, both options offer enjoyable typing experiences. Depending on your preferences, you can achieve similar results with either switch.
Conclusion
Bringing it all together, when deciding between the SP-Star RedBlue linear switch and the Kailh Sage clicky switch, there are a few key factors to consider.
If you prefer a medium-light typing experience and a relatively higher-pitched sound profile, the SP-Star RedBlue switches are the way to go. These switches have a bottom out force of 57 grams, making them suitable for those who prefer a lighter touch when typing. The sound produced by the RedBlue switches is described as low-pitched, which results in a more bass-heavy and mellow tone. Additionally, the feel of the RedBlue switches can be described as mild and polished, offering a gentle typing experience with a smooth and refined finish.
On the other hand, if you enjoy a distinct clicky typing experience and prefer a medium-heavy typing force, the Kailh Sage switches are an excellent choice.
