Housing materials

The HMX EMO and KTT Purple Star differ in their choice of housing materials, specifically in their top and bottom housings. The EMO utilizes a polycarbonate top housing, which provides a sharper, higher-pitched sound profile due to its stiffness and resonant qualities. On the other hand, the Purple Star opts for a POM top housing, resulting in a deeper and more muted sound. Both switches offer unique sound profiles, but the EMO's polycarbonate top housing emphasizes clarity and crispness, while the Purple Star's POM top housing leans towards a richer and deeper sound experience.

In terms of bottom housings, the EMO features a nylon material known for creating a deeper and fuller sound profile. The softness of nylon absorbs more sound, resulting in a duller and rounder sound compared to harder plastics. Similarly, the Purple Star's POM bottom housing offers a unique and pleasing sound profile on the deeper end, contributing to a more muted sound overall. While both switches showcase different housing materials for their bottom housings, they both aim to enhance the user's typing experience with unique sound profiles that cater to different preferences.

Overall, the choice of housing materials in switches like the HMX EMO and KTT Purple Star plays a crucial role in shaping the sound profile and typing experience. While the EMO may offer a sharper and crisper sound with its polycarbonate top housing and nylon bottom housing, the Purple Star provides a deeper and more muted sound with its POM top and bottom housings. Despite these differences, both switches prioritize creating a unique and enjoyable typing experience for users, showcasing the varying impact of different housing materials on sound and feel.
