Aflion Blush vs. SP-Star RedBlue

An in-depth look at the Aflion Blush and the SP-Star RedBlue switches—which one is the best fit for you?

Overview

The Aflion Blush and SP-Star RedBlue are two mechanical keyboard switches that offer different experiences to suit different preferences. The Blush is best known for its impressively smooth and snappy feel, thanks to its longer, two-stage spring. It also provides a poppy sound signature, making it ideal for those who enjoy a more tactile and audible typing experience. On the other hand, the RedBlue switches are particularly suited for those who prefer a medium-light typing experience. They offer a higher-pitched sound profile and are categorized as low-pitched, neutral, mild, thocky, and polished. Both switches have their unique characteristics and advantages, however, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The Aflion Blush and the SP-Star RedBlue share similarities in their top housings as both utilize polycarbonate materials. Polycarbonate has the advantage of creating a sharper, higher-pitched, and crisper sound profile due to its relatively stiff nature. Additionally, the translucent property of polycarbonate makes it ideal for switches that incorporate RGB lighting. Therefore, users can expect similar sound characteristics and aesthetic benefits when using both the Blush and RedBlue switches.

However, where these two switches differ is in their bottom housings. The Blush features a nylon bottom housing, which is known for producing a deeper and fuller sound profile. This is attributed to nylon being a softer plastic that absorbs more sound than harder plastics, resulting in a duller and rounder sound. On the other hand, the RedBlue utilizes a polycarbonate bottom housing, which offers a sharper, higher-pitched, and crisper sound. The stiffness of polycarbonate contributes to a clear and resonant sound profile. Therefore, typing on the Blush switch will provide a different auditory experience compared to the RedBlue switch, with the former offering a deeper and fuller sound, while the latter delivers a sharper and crisper sound.

It is worth mentioning that the impact of the housing materials on the overall sound profile is also divided between the top and bottom of the switch. The bottom housing primarily influences the bottom-out sound and feel when the key is pressed, while the top housing has a greater impact on the sound produced when releasing a key. As a result, users may notice variations in sound depending on whether they press or release the keys. Nonetheless, both the Blush and RedBlue switches will offer unique acoustic characteristics contributed by their respective housing materials.

Weight

When comparing the actuation force and bottom out force of the Aflion Blush linear switch and the SP-Star RedBlue linear switch, there are a few key differences to note. The actuation force for both switches is unavailable, meaning we do not have specific information on this aspect. However, in terms of bottom out force, the Blush requires 58 grams of force, which is considered medium, while the RedBlue requires 57 grams of force, which is considered medium-light.

For those who prefer a lighter typing experience, the SP-Star RedBlue linear switch with its slightly lower bottom out force may be the preferred option. This lighter force allows for longer periods of comfortable typing, making it suitable for work or extended gaming sessions. On the other hand, for individuals who enjoy a more substantial typing experience with a stronger push feel, the Aflion Blush linear switch may be a better choice. Although both switches fall within the medium range of bottom out force, the Blush is slightly heavier at 58 grams compared to the RedBlue's 57 grams.

It is important to consider weight when choosing a switch, as it can significantly impact typing comfort and endurance. Ultimately, the decision between the Aflion Blush linear switch and the SP-Star RedBlue linear switch will depend on personal preference and typing style.

Travel distance

The travel distance of the Aflion Blush linear switch is 3.3 mm, while the SP-Star RedBlue linear switch has a travel distance of 4 mm. In terms of length, the RedBlue has a longer travel distance compared to the Blush. The 4.0mm travel distance of the RedBlue is the more traditional option, offering a deeper feel when pressing down on a key. However, the Blush's 3.3 mm travel distance is considered shorter and is preferred by gamers who prioritize faster response times. Opting for the shorter travel distance of the Blush can provide a more responsive typing experience. Ultimately, the choice between the two switches will depend on individual preference and whether one prefers a shallower and quicker response or a deeper and more substantial feel when pressing down on the keys.
