HMX Blue Topaz vs. Bsun Bumblebee Linear
An in-depth look at the HMX Blue Topaz and the Bsun Bumblebee Linear switches—which one is the best fit for you?
Overview
When it comes to selecting the perfect mechanical keyboard switch, two noteworthy contenders are the HMX Blue Topaz and the Bsun Bumblebee Linear, both of which are linear switches catering to different user preferences. The HMX Blue Topaz stands out for its ultra-smooth actuation and lightweight feel, making each keystroke effortless—ideal for users who enjoy a more tactile experience. Its visually striking housing, adorned with a unique glitter finish, is complemented by a satisfying clacky sound signature that appeals to those who relish auditory feedback while typing. On the other hand, the Bsun Bumblebee Linear offers an equally smooth typing experience, characterized by a bright sound profile that enhances the tactile pleasure of keystrokes without the additional clackiness. While both switches excel in delivering a linear typing feel, their distinct auditory characteristics and design elements cater to varied aesthetic and functional preferences. 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 the Bsun Bumblebee Linear switches showcase distinct differences in their top housing materials, influencing the overall sound profile of each switch. The Blue Topaz features a polycarbonate top housing, renowned for producing a sharper, higher-pitched sound, applauded for its clarity and resonance. Its translucency makes it particularly well-suited for RGB lighting applications, as light can effectively pass through, creating a visually appealing experience. In contrast, the Bumblebee Linear employs a POM top housing, which contributes to a more muted and deeper sound profile. This inherent characteristic of POM can produce a unique auditory experience, focusing on a warmer and less pronounced tonal range compared to the crispness of polycarbonate.
Both switches, however, share a commonality in their bottom housing, which is made from nylon. This choice results in a deeper and fuller sound profile for both models, as nylon is known for its sound-absorbing qualities. With nylon being a softer plastic, it plays a significant role in the overall sound experience of both switches. Both switches benefit from this nylon bottom that helps dampen sounds, leading to a more rounded auditory experience whether you’re typing on the Blue Topaz or the Bumblebee Linear. This continuity in material choice at the bottom provides a familiar feel across both switch types, highlighting the traditional and reliable characteristics of nylon as a classic switch housing material.
Ultimately, the differences in the top housing materials between the Blue Topaz and Bumblebee Linear dictate their distinct sound profiles, but the similar nylon bottoms help maintain an overarching depth and fullness in sound. Users can expect different auditory results depending on the top housing—sharper from the Blue Topaz and deeper from the Bumblebee Linear—yet the pairing of nylon at the bottom ensures a consistent sensation when bottoming out the keys. Thus, while each switch offers a unique auditory experience, the shared nylon material converges their characteristics, unifying them under the classic qualities of durability and sound absorption inherent to nylon switch housings.
Weight
When comparing the actuation and bottom out forces of the HMX Blue Topaz linear switch and the Bsun Bumblebee Linear switch, we find a small yet notable difference in their specifications. The Blue Topaz features an actuation force of 40 grams and a bottom out force of 48 grams, while the Bumblebee Linear has slightly heavier actuation and bottom out forces at 45 grams and 50 grams, respectively. This means that, in general, the Blue Topaz is the lighter option, making it potentially more suitable for longer typing sessions or extended gaming, as it requires less effort to register a keystroke. Conversely, the Bumblebee Linear’s heavier forces may appeal to those who prefer a more substantial feel when typing, providing the tactile feedback that some users seek. Overall, while both switches are categorized as light, the Blue Topaz offers a marginally lighter experience compared to the Bumblebee Linear.
Travel distance
When comparing the travel distance of the HMX Blue Topaz linear switch and the Bsun Bumblebee Linear switch, the Blue Topaz measures 3.9 mm, while the Bumblebee Linear features a shorter travel distance of 3.6 mm. This difference makes the Bumblebee Linear the more responsive option, appealing to gamers who favor faster response times. Conversely, the Blue Topaz, with its longer travel distance, may provide a more substantial tactile experience for those who prefer deeper key presses. Both switches offer a unique feel, catering to different preferences—whether one seeks quick action or a more pronounced depth. Therefore, if responsiveness is paramount, the Bumblebee Linear is the optimal choice, whereas the Blue Topaz caters to those who enjoy a more robust key press feel.

Typing experience
The HMX Blue Topaz linear switch offers a distinctly clacky sound profile, which is known for its crisp and percussive quality, resulting in a lively auditory experience that many typists and gamers appreciate. The clacky resonance adds an engaging layer to the typing experience, making every keystroke feel more pronounced. In contrast, while specific details of the sound profile of the Bsun Bumblebee Linear switch aren't thoroughly described, the mention of a "bright sound profile" suggests that it, too, produces a clear and upbeat auditory feedback. However, without the same emphasis on clackiness, the Bumblebee may present a more subdued yet still pleasant sound that differs from the punchy resonance of the Blue Topaz.
When it comes to feel, the Blue Topaz excels with its easy-to-press action, characterized by gentle resistance that contributes to an effortless typing experience. Its lightweight nature significantly reduces finger fatigue during lengthy typing sessions, making it user-friendly for both casual typing and gaming. The Bumblebee Linear switch, though not detailed in terms of its feel, is categorized as a linear switch, which typically implies a smooth and consistent keypress without any tactile bumps or click feedback. As a result, it is also likely to showcase a smooth feel similar to that of the Blue Topaz, potentially offering comparable comfort and fluidity when typing.
In conclusion, while the HMX Blue Topaz and Bsun Bumblebee Linear switches both promise high-quality typing experiences, they present different sound signatures, with the Blue Topaz leaning towards a clacky sound, whereas the Bumblebee leans towards a brighter, potentially more understated tone. In terms of feel, the Blue Topaz’s lightweight and easy-to-press characteristics may offer a distinct advantage, but the Bumblebee, as a linear switch, can still provide a smooth typing experience. Ultimately, while there may be differences in sound, users can expect a satisfactory and enjoyable experience from both switches, with particular characteristics that might cater to different personal preferences.
Conclusion
To conclude, your choice between the HMX Blue Topaz linear switch and the Bsun Bumblebee Linear switch ultimately hinges on your personal preferences for sound, feel, and typing experience. If you value a super smooth actuation combined with a lightweight, effortless keystroke, then the Blue Topaz is an ideal option for you. Its clacky sound signature not only adds auditory delight but can also make your typing feel more engaging, particularly if you enjoy the tactile feedback and lively character it provides. This makes it a great choice for general typing, casual gaming, and creative tasks where a bit of audio feedback enhances the experience.
On the other hand, if you prefer a more neutral typing experience without the clack, the Bumblebee Linear switch will serve you better. With a similar lightweight feel, it excels in environments where noise might be a factor, such as office settings or shared workspaces, thanks to its bright sound profile that is still pleasant but less pronounced. The 50-gram bottom-out force ensures a slightly more substantial feel, which may appeal to those who seek a bit more resistance during key presses, thus reducing the risk of accidentally triggering keys during intense typing or gaming sessions. Ultimately, your decision should reflect what you find most enjoyable in your daily usage, whether it’s the lively feedback of the Blue Topaz or the smooth, subtle experience offered by the Bumblebee.
