Housing materials

When comparing the housing materials of the HMX Blue Topaz and the Gazzew U4T, both switches feature unique materials that contribute to their sound profiles. The Blue Topaz utilizes a polycarbonate top housing, which provides a sharper and crisper sound profile due to its stiffness. In contrast, the U4T's proprietary Gazzew blend top housing, also known as "boba plastic," offers a rich and deep sound profile thanks to its softness. While the Blue Topaz's polycarbonate top housing focuses on clarity and resonance, the U4T's Gazzew blend top housing emphasizes depth and richness.

Moving on to the bottom housing materials, the Blue Topaz features a nylon bottom housing that creates a deeper and fuller sound profile because of its softer nature. In contrast, the U4T's proprietary Gazzew blend bottom housing mirrors its top housing, delivering a rich and deep sound profile due to its softness. Both switches prioritize sound quality by utilizing materials that absorb sound differently, with the Blue Topaz focusing on creating a rounder sound while the U4T aims for a rich and deep sound experience.

Overall, the housing materials used in the HMX Blue Topaz and the Gazzew U4T play a crucial role in shaping the sound profiles of these switches. While the Blue Topaz combines polycarbonate for its top housing and nylon for its bottom housing to create a balance between sharpness and fullness, the U4T utilizes its proprietary Gazzew blend for both top and bottom housings to emphasize richness and depth. Despite their differences, both switches aim to provide a satisfying typing experience through the careful selection of housing materials, ensuring that users will get similar results in terms of sound quality.
