HMX Blue Topaz vs. Durock Dolphin
An in-depth look at the HMX Blue Topaz and the Durock Dolphin switches—which one is the best fit for you?
Overview
When choosing between the linear switches HMX Blue Topaz and Durock Dolphin, it ultimately comes down to personal preference and specific needs. The HMX Blue Topaz offers a super smooth actuation and lightweight feel, ideal for those seeking an easy-to-press switch with a clacky sound signature. On the other hand, the Durock Dolphin is a silent switch with a medium-heavy actuation force of 62g, perfect for office environments or users who prefer a more muted, low-pitched 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
Both the HMX Blue Topaz and the Durock Dolphin feature polycarbonate top housings, which are known for creating a sharper, higher-pitched, and crisper sound profile. This is due to the stiffness of polycarbonate, which leads to a more clear and resonant sound. Additionally, the translucency of polycarbonate makes it ideal for switches with RGB lighting, as it allows the light to shine through. The similarities in the top housing material suggest that users can expect a similar auditory experience from both switches.
On the other hand, the Blue Topaz utilizes a nylon bottom housing, which results in a deeper and fuller sound profile compared to the stiffer polycarbonate. Nylon is known for absorbing more sound than harder plastics, creating a duller and rounder sound. Similarly, the Durock Dolphin also features a nylon bottom housing, showcasing a focus on providing a more muted and softer sound experience. Despite having different top housings, the use of nylon in the bottom housing for both switches suggests a shared emphasis on creating a particular sound aesthetic.
When considering the impact of housing materials on the overall typing experience, it is important to recognize how the qualities of the top and bottom housing contribute to the sound and feel of the switch. The split between the top and bottom housing materials allows for a nuanced auditory experience, with the bottom housing influencing the bottom-out sound and feel, while the top housing has a greater impact on the sound when a key is released. Understanding the role of each housing material can help users choose a switch that suits their preferences for sound and typing feel.
Weight
When comparing the actuation force and bottom out force of the HMX Blue Topaz linear switch and the Durock Dolphin linear switch, one can see the differences in weight between the two. The Blue Topaz has a lighter actuation force of 40 grams and a lighter bottom out force of 48 grams, making it a great choice for those who prefer a lighter touch while typing. On the other hand, the Dolphin switch has a heavier bottom out force of 62 grams, providing a more substantial typing experience for those who prefer a bit more resistance. The actuation force of the Dolphin switch is unknown, but with its heavier bottom out force, it can be assumed to require a bit more force to trigger a keystroke compared to the Blue Topaz. Overall, the Blue Topaz is lighter in weight, while the Dolphin is heavier, allowing users to choose based on their preference for a lighter or heavier typing experience.
Travel distance
The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, while the Durock Dolphin linear switch has a travel distance of 3.8 mm. Both switches are relatively close in terms of travel distance, with the Blue Topaz being slightly longer than the Dolphin. In general, a shorter travel distance is preferred by gamers for faster response times, while a longer travel distance may provide a more satisfying tactile feel. Ultimately, the decision between the two switches will depend on personal preference and the desired typing or gaming experience.
