HMX Blue Topaz vs. KTT Darling

An in-depth look at the HMX Blue Topaz and the KTT Darling switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, the HMX Blue Topaz and KTT Darling stand out as two exceptional options, both offering unique characteristics that cater to different preferences. The Blue Topaz's linear switch is lauded for its smooth actuation and light feel, providing users with a seamless typing experience accompanied by a satisfying clacky sound. On the other hand, the Darling linear switch from KTT offers a chewy and substantial typing sensation with a pronounced bounciness, creating a springy responsiveness and delivering a resonant, high-pitched sound. While the Blue Topaz may appeal to those looking for an easy-to-press switch with a clacky sound, the Darling is perfect for individuals seeking a bouncy, high-pitched switch with substantial tactile feedback. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The HMX Blue Topaz and KTT Darling both feature polycarbonate top housings, which contribute to a sharper, higher-pitched, and crisper sound profile. The use of polycarbonate in these housings results in a more clear and resonant sound due to its relatively stiff nature. Additionally, the translucency of polycarbonate makes it ideal for switches designed with RGB lighting in mind. However, when it comes to the nylon bottom housings, there are slight differences. The Blue Topaz's nylon bottom housing produces a deeper and fuller sound profile compared to the Darling's nylon bottom housing, which absorbs more sound and creates a duller and rounder sound.

While both the Blue Topaz and Darling share polycarbonate top housings, their differences lie in the material of their bottom housings. The Blue Topaz's nylon bottom housing offers a deeper and fuller sound experience, whereas the Darling's nylon bottom housing absorbs more sound, resulting in a duller and rounder sound. This contrast highlights how different housing materials can impact the overall sound profile of a switch. Despite their similarities in the top housing material, the choice of bottom housing material in each switch contributes to distinct typing experiences for users.

In summary, the HMX Blue Topaz and KTT Darling both excel in sound quality due to their polycarbonate top housings, creating sharp, clear, and resonant sound profiles. However, their nylon bottom housings present a contrast in sound experiences, with the Blue Topaz offering a deeper tone and the Darling producing a duller sound. The split characteristics of the housing materials in these switches demonstrate how the bottom housing influences the bottom-out sound and feel, while the top housing impacts the sound when releasing a key. Ultimately, the choice between the Blue Topaz and Darling will depend on individual preferences for sound profiles and typing experiences.

Weight

The HMX Blue Topaz linear switch has a lighter actuation force and bottom out force compared to the KTT Darling linear switch. The Blue Topaz requires 40 grams of force to actuate and 48 grams to bottom out, while the Darling requires 45 grams to actuate and 53 grams to bottom out. The difference in force may result in a slightly lighter typing experience with the Blue Topaz and a slightly heavier typing experience with the Darling. For those who prefer a lighter feel when typing for extended periods of time, the Blue Topaz may be the better choice. However, for those who prefer a more substantial typing experience with a bit more resistance, the Darling may be the preferred option. Ultimately, the choice between the two switches will depend on personal preference and typing style.

Travel distance

The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, while the KTT Darling linear switch has a travel distance of 3.5 mm. Both switches fall within the range of shorter travel distances preferred by gamers for faster response times. However, the Blue Topaz has a slightly longer travel distance than the Darling. This means that if you prefer a bit more depth to your keystrokes, the Blue Topaz may be the better option for you. On the other hand, if you prefer a more immediate and snappy feel to your key presses, the Darling with its slightly shorter travel distance may be more suitable. Ultimately, the choice between the two will come down to personal preference in terms of how much travel distance you prefer when typing or gaming.
