HMX Blue Topaz vs. Gazzew Bobagum
An in-depth look at the HMX Blue Topaz and the Gazzew Bobagum switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, the HMX Blue Topaz and the Gazzew Bobagum both offer unique qualities that cater to different preferences. The Blue Topaz linear switch stands out for its super smooth actuation and lightweight feel, providing a seamless typing experience with a clacky sound signature that adds to the overall tactile sensation. On the other hand, the Bobagum switch boasts a distinct matte feel that offers unparalleled tactility and a nearly silent sound profile, making it ideal for those who prefer a more muted and subtle typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the HMX Blue Topaz and the Gazzew Bobagum differ in terms of their composition and resulting sound profiles. The Blue Topaz features a polycarbonate top housing, which is known for creating a sharper and crisper sound due to its stiffness. In contrast, the Bobagum utilizes a proprietary Gazzew blend for its top housing, resulting in a rich and deep sound profile thanks to the softness of the material. While both materials offer unique sound characteristics, the polycarbonate of the Blue Topaz provides a more resonant and clear sound, whereas the Gazzew blend of the Bobagum delivers a deeper and fuller sound experience.
In terms of their bottom housings, the Blue Topaz utilizes nylon, a classic switch housing material known for producing a deep and full sound profile. The softness of nylon absorbs more sound than harder plastics, creating a duller and rounder sound compared to other materials. Conversely, the Bobagum also incorporates the proprietary Gazzew blend for its bottom housing, resulting in a rich and deep sound profile similar to its top housing. Both housings aim to enhance the overall sound experience of the switch, with nylon offering a more mellow tone and the Gazzew blend providing a rich and deep sound quality.
Overall, the differing housing materials of the HMX Blue Topaz and the Gazzew Bobagum each bring their own unique characteristics to the switches. While the Blue Topaz features a combination of polycarbonate and nylon for its top and bottom housings respectively, the Bobagum utilizes the proprietary Gazzew blend for both components. Despite the variation in materials, both switches aim to enhance the sound profile through the unique properties of their housing materials. Whether using polycarbonate or the Gazzew blend, users can expect a heightened sound experience that complements the overall performance of the switch.
Weight
When comparing the actuation force and bottom out force of the HMX Blue Topaz linear switch and the Gazzew Bobagum linear switch, it is clear that the Blue Topaz is the lighter option with an actuation force of 40 grams and a bottom out force of 48 grams. On the other hand, the Bobagum is the heavier choice, with an actuation force of 46 grams and a bottom out force of 62 grams. The lighter actuation force of the Blue Topaz may be preferred by those who want a more effortless typing experience for extended periods, while the heavier actuation force and bottom out force of the Bobagum provide a more substantial typing feel. Ultimately, the choice between the two switches depends on personal preference in terms of typing experience.
Travel distance
The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, which is slightly longer than the Gazzew Bobagum linear switch with a travel distance of 3.6 mm. Both switches fall within the range of shorter travel distances that are popular among gamers for faster response times. The Blue Topaz offers a slightly deeper key press compared to the Bobagum, which may be preferable for those who enjoy a more substantial typing experience. However, for those who prefer a quicker and more responsive feel, the Bobagum's slightly shorter travel distance may be the better option. In general, both switches offer similar results in terms of travel distance, providing users with a choice based on their personal preference for key press depth.

Typing experience
When it comes to sound, the HMX Blue Topaz linear switch offers a clacky typing experience, producing a sharp and snappy sound that is crisp, bright, and percussive. On the other hand, the Gazzew Bobagum linear switch provides a much more muted sound profile, delivering a softer and quieter typing experience that minimizes the noise typically associated with mechanical keyboards. Depending on personal preference, users may prefer the more distinct sound of the Blue Topaz or the quieter typing experience of the Bobagum.
In terms of feel, the Blue Topaz linear switch is praised for its easy-to-press nature, offering gentle resistance during key presses that require minimal force to activate. This light actuation force makes typing effortless and comfortable, reducing finger fatigue during extended use. In comparison, the Gazzew Bobagum switch provides a subtle typing experience with a gentle resistance that is not too light but still maintains a comfortable feel. The typing experience is further enhanced by the lack of a resonant sound signature, making the Bobagum switch suitable for shared spaces where noise may be a concern.
Overall, the HMX Blue Topaz and Gazzew Bobagum linear switches offer unique qualities that cater to different preferences in the mechanical keyboard community. The Blue Topaz excels in providing a smooth actuation and a clacky sound signature, while the Bobagum stands out with its matte feel, tactile feedback, and muted sound profile. Depending on whether you prioritize smoothness and audible feedback or subtlety and quietness in your typing experience, both switches offer excellent options for customization and personalization. Ultimately, regardless of your choice, you can expect a high-quality typing experience with either switch.
Conclusion
In conclusion, when deciding between the HMX Blue Topaz linear switch and the Gazzew Bobagum linear switch, consider your preference for bottom out force, sound profile, and typing feel. If you prefer a lighter bottom out force and a clacky sound with smooth actuation, the Blue Topaz may be the ideal choice for you. On the other hand, if you prefer a medium bottom out force, a muted sound profile, and a subtle typing feel, the Bobagum may be more to your liking. Ultimately, your decision should align with your personal preferences for typing experience, sound, and force feedback. Choose the switch that best suits your typing style and preferences for a truly enjoyable mechanical keyboard experience.
