Housing materials
The housing materials of the Bsun Akashi and SP-Star Yanyu switches both bring unique characteristics to the overall sound profile of the switches. The Akashi's POM top housing creates a deeper and more muted sound, while the Yanyu's Polymer nylon and UHMWPE blend top housing offers a brighter sound profile. Both materials provide a pleasing sound experience, but with different tonal qualities. In terms of bottom housing, the Akashi's nylon material produces a deep and fuller sound, while the Yanyu's Polymer nylon and UHMWPE blend bottom housing offers a brighter sound profile. Each switch utilizes its housing materials to create a distinct auditory experience for the user.
While the Akashi and Yanyu switches both utilize nylon in their bottom housing, the top housings are where they differ significantly. The POM top housing of the Akashi provides a unique sound profile that is deeper and more muted, contrasting with the Polymer nylon and UHMWPE blend top housing of the Yanyu, which offers a brighter sound. These differences in top housing material contribute to the overall tone and feel of each switch, providing users with a variety of options depending on their preferences for sound and typing experience. Despite the differences in top housing, both switches aim to deliver a satisfying sound experience for mechanical keyboard enthusiasts.
When comparing the impact of the top and bottom housing materials on the overall sound profile of the switches, it is evident that both components play a crucial role in shaping the typing experience. The bottom housing material, whether nylon in the case of the Akashi or the Polymer nylon and UHMWPE blend in the Yanyu, influences the bottom-out sound and feel of the switch. On the other hand, the top housing material, such as POM for the Akashi or the Polymer nylon and UHMWPE blend for the Yanyu, affects the sound when releasing a key. By combining different housing materials in the top and bottom components, manufacturers can create switches with unique and customizable sound profiles to cater to a variety of user preferences.
Weight
When comparing the Bsun Akashi linear switch and the SP-Star Yanyu linear switch, the actuation force of the Akashi is 37 grams, while the Yanyu's actuation force is unknown. Both switches have a bottom out force of 43 grams. This means that both switches have a relatively light actuation force, making them suitable for users who prefer a lighter typing experience. When it comes to weight, the Akashi can be considered the lighter option between the two. Some users may prefer the Akashi for longer typing sessions or extended gaming sessions due to its lighter actuation force. However, for those who prefer a more substantial typing experience with a stronger push feel, the Yanyu may be the better choice, despite its unknown actuation force. Ultimately, the decision between the two switches will depend on personal preference and typing style.
Travel distance
The Bsun Akashi linear switch has a travel distance of 3.7 mm, while the SP-Star Yanyu linear switch has a travel distance of 4 mm. In this case, the Yanyu has a slightly longer travel distance compared to the Akashi. Both switches fall within the range of shorter travel distances, making them ideal for gamers looking for quick response times. However, the Akashi may feel slightly more abrupt due to its shorter travel distance, while the Yanyu offers a bit more depth in key press. Ultimately, the choice between the two switches will depend on personal preference for travel distance and typing feel.
