An in-depth look at the HMX Blue Topaz and the Gazzew U4 switches—which one is the best fit for you?
Overview
The HMX Blue Topaz and Gazzew U4 mechanical keyboard switches offer distinct experiences for users to consider. The Blue Topaz boasts a linear design, delivering smooth actuation and a lightweight feel that makes typing a breeze. With its eye-catching glittery housing and clacky sound signature, it appeals to those looking for both visual and auditory delight in their typing experience. On the other hand, the Gazzew U4 stands out with its tactile nature, providing a sharp tactile bump and a plush, felt-like bottom-out sensation.

Housing materials
The housing materials of the HMX Blue Topaz and Gazzew U4 switches offer unique characteristics that contribute to the overall sound profile and feel of the switch. The Blue Topaz features a polycarbonate top housing known for creating a sharper, higher-pitched sound with a clear and resonant profile. In comparison, the U4's proprietary Gazzew blend top housing delivers a rich and deep sound due to its softness. While the Blue Topaz's top housing emphasizes clarity and brightness, the U4's top housing focuses on creating a warmer and more resonant sound.
In terms of the bottom housing materials, the Blue Topaz utilizes a nylon bottom housing that produces a deeper and fuller sound profile thanks to its softer nature, which absorbs more sound. On the other hand, the U4's proprietary Gazzew blend bottom housing also delivers a rich and deep sound profile due to its softness, similar to its top housing material. Both switches prioritize creating a rounder and more muffled sound with their bottom housing materials, providing a different typing experience compared to switches with harder plastic bottom housings.
When both top and bottom housings differ in a switch, the qualities of each housing material will impact different aspects of the typing experience. The bottom housing influences the bottom-out sound and feel of the switch, while the top housing affects the sound when releasing a key. In the case of the Blue Topaz and Gazzew U4, their unique housing materials work together to create distinct sound profiles and typing feels that cater to different preferences among mechanical keyboard enthusiasts.
Weight
The actuation force and bottom out force of the HMX Blue Topaz linear switch and the Gazzew U4 tactile switch offer different experiences for users. The Blue Topaz has a lighter actuation force of 40 grams and a bottom out force of 48 grams, making it suitable for those who prefer a lighter touch. In contrast, the U4 has a heavier actuation force of 45 grams and a bottom out force of 62 grams, providing a more substantial typing experience for users who prefer a stronger push feel. The lighter actuation force of the Blue Topaz makes it ideal for long typing sessions or gaming marathons, while the heavier forces of the U4 cater to those seeking a more substantial typing experience. Ultimately, choosing between the two switches will depend on personal preference for typing feel and force requirements.
Travel distance
The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, while the Gazzew U4 tactile switch has a travel distance of 3.6 mm. This makes the U4 the shorter option compared to the Blue Topaz. A shorter travel distance can provide faster response times, which may be preferred by gamers. On the other hand, a longer travel distance can offer a more substantial feeling when pressing down on the key. Both switches fall within the range of modern travel distances, making them suitable for various preferences. Ultimately, the choice between the two will depend on whether you prioritize speed and responsiveness or a more tactile and deep key press.
