Housing materials

The Bsun Akashi and the SP-Star Polaris Purple both have distinct differences in their housing materials. The Akashi features a POM top housing which creates a deeper and relatively muted sound profile. On the other hand, the Polaris Purple utilizes a polycarbonate top housing which produces a sharper, higher-pitched, and crisper sound. This contrast in sound profiles can significantly affect the typing experience for users, as the Akashi may provide a more subtle and quieter typing experience compared to the Polaris Purple's more noticeable and crisp sound.

In terms of the bottom housing, the Akashi's nylon bottom housing provides a deeper and fuller sound profile due to its softer plastic that absorbs more sound. In comparison, the Polaris Purple's polycarbonate bottom housing offers a sharper and more resonant sound profile thanks to its stiffer plastic composition. The difference in sound profiles between the bottom housings of these two switches can cater to different preferences among users, with the Akashi offering a more muffled sound and the Polaris Purple delivering a clearer and crisper typing experience.

Ultimately, the choice between the Bsun Akashi and the SP-Star Polaris Purple will come down to personal preference in sound profile and typing experience. Both switches have unique qualities in their housing materials that can impact the overall feel and sound of typing. While the Akashi offers a more muted sound with its POM top housing and nylon bottom housing, the Polaris Purple provides a sharper and more resonant sound with its polycarbonate top and bottom housings. Users looking for a softer typing experience may prefer the Akashi, while those seeking a crisper and clearer sound profile may lean towards the Polaris Purple.
