Kailh BCP vs. Durock Sea Glass
An in-depth look at the Kailh BCP and the Durock Sea Glass switches—which one is the best fit for you?
Overview
When it comes to choosing the perfect linear mechanical keyboard switch, the Kailh BCP and Durock Sea Glass offer distinct experiences that cater to different typing preferences. The Kailh BCP is a refreshing take on the classic Black Cherry Pie switches, known for its creamy, elastic feel that delivers a uniquely bouncy experience. This switch is characterized by its poppy, clacky sound profile, making it an excellent choice for those who enjoy auditory feedback and a tactile sensation while typing. In contrast, the Durock Sea Glass series stands out with its array of vibrant pastel colors and a typing experience that is defined by its distinct dryness, wispiness, and airiness. Despite a bottom-out force of 62g, the Sea Glass switches surprise users with a lightweight feel that promotes a smooth typing experience without sacrificing performance. The hollow sound signature of the Sea Glass adds an additional layer of novelty that appeals to those seeking a softer auditory 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 Kailh BCP switch features housing made entirely from nylon, a classic material known for its ability to create a deeper and fuller sound profile due to its softer texture. The nylon top housing absorbs sound efficiently, leading to a more rounded acoustic experience. The same principle applies to the nylon bottom housing, which contributes to the overall richer sound quality by further dampening high-frequency noises. This combination creates a consistent auditory experience throughout the typing action, as both the top and bottom housings share similar properties that fortify the switch’s sound signature.
In contrast, the Durock Sea Glass switch utilizes a more complex blend of Polymer nylon and UHMWPE for both the top and bottom housings. While this mixture still incorporates nylon, it introduces new characteristics that result in a sound profile described as pleasant and slightly brighter compared to the BCP. Although the Sea Glass’s blend adds a unique texture, both switches experience sound absorption to some degree thanks to their nylon components. The Sea Glass's blend allows for a differentiation in sound quality, providing a subtle crispness that distinguishes it from the deeper tones found in the BCP’s solely nylon construction.
Despite the differences in materials, both the Kailh BCP and Durock Sea Glass switches provide distinct auditory experiences shaped by their respective housing designs. The nylon in the BCP promotes a duller sound, while the Sea Glass’s blend results in a brighter profile. However, if the top and bottom housings differ, as is the case in these switches, the overall experience can still be comparable. The bottom housing’s impact on the bottom-out feel and sound is critical, while the top housing influences the sound when a key is released. This interplay means that despite their material composition variances, both switches can achieve favorable auditory qualities, albeit through different sound signatures.
Weight
When comparing the Kailh BCP linear switch and the Durock Sea Glass linear switch, we can observe notable differences in their actuation and bottom out forces. The BCP switch has a heavier actuation force of 52 grams and a bottom out force of 63.5 grams, making it a medium-heavy option suitable for those who prefer a more substantial typing experience. In contrast, the Sea Glass switch features a lighter actuation force of 45 grams and a bottom out force of 62 grams, categorized as medium, which may appeal to users seeking a gentler touch for prolonged typing or gaming sessions. Consequently, the Kailh BCP is the heavier option between the two, while the Durock Sea Glass offers a lighter feel, allowing for easier keystrokes. This difference in actuation force means that while both switches provide a satisfying typing experience, the Sea Glass will likely be more comfortable for extended use, whereas the BCP could appeal to those who prefer a firmer key press.
Travel distance
When comparing the travel distances of the Kailh BCP linear switch and the Durock Sea Glass linear switch, we find that they diverge in their measurements. The Kailh BCP has a travel distance of 3.5 mm, while the Durock Sea Glass offers a slightly longer travel distance of 3.8 mm. This means that the BCP is the shorter option, making it potentially more responsive for users who prefer quicker key presses, such as gamers. In contrast, the longer travel distance of the Sea Glass might appeal to those who appreciate a more pronounced tactile feedback and depth in their keystrokes. For individuals seeking a balance between responsiveness and depth, the Sea Glass could be the preferred choice, while the BCP might suit those favoring speed and swiftness in their typing or gaming experience.

Typing experience
In terms of sound, the Kailh BCP linear switch is characterized by a signature poppy and clacky sound profile, which is often appealing for users who enjoy an audible typing experience reminiscent of traditional mechanical switches. On the other hand, the Durock Sea Glass switch produces a uniquely hollow sound signature, which can impart a different auditory feedback that some may find intriguing or even calming. While the distinct sound profiles of both switches cater to varying tastes, it’s important to note that the overall sound produced by each switch can be significantly influenced by the keyboard case and keycap material chosen.
Regarding feel, the BCP switch provides a creamy, viscous, elastic, and bouncy sensation, creating an engaging tactile feedback that can make every keystroke feel satisfying. In contrast, the Sea Glass switch is crafted with a proprietary material blend that results in a typing experience that is described as frictionless, mild, feathery, and easy-to-press. This combination leads to an exceptionally smooth and lightweight feel, which is less resistant and ideal for users looking for minimal exertion during typing. While the BCP may deliver a more pronounced tactile experience with notable feedback, the Sea Glass offers a gentler, more responsive feel that reduces finger fatigue without sacrificing smoothness.
Combining all these attributes, both the Kailh BCP and Durock Sea Glass linear switches bring unique qualities to the table. The BCP’s more audible and tactile experience can cater to those who appreciate a lively typing environment, while the Sea Glass switch provides a lighter touch and a serene, airy auditory presence. Depending on your preferred typing experience, you will find similar results in terms of key press effort with the BCP's bouncy nature contrasting with the Sea Glass's feathery lightness, each appealing to different user preferences. Ultimately, your choice will depend on whether you value a vibrant sound and feel or prioritize a smooth and effortless typing experience.
Conclusion
To conclude, the choice between Kailh BCP linear switches and Durock Sea Glass linear switches ultimately comes down to your personal preferences and typing style. If you prefer a more pronounced tactile experience with a medium-heavy keystroke and enjoy the satisfying poppy and clacky sound profile that the BCP offers, then you might find this switch to be your ideal match. The creamy, bouncy feel of the Kailh BCP will likely appeal to those who enjoy a bit more resistance and feedback during their typing sessions. On the other hand, if you lean towards a lighter, more effortless typing experience, the Durock Sea Glass switches may be your best option. With their 62g bottom-out force, they provide a frictionless and feathery touch that can help minimize finger fatigue, making them perfect for long hours of use, whether for work or gaming. The uniquely airy sound signature also adds an appealing quality for those who appreciate quieter, more subtle acoustics. Ultimately, consider what aspects are most important to you—whether it’s the tactile engagement of the BCP or the smooth, weightless feel of the Sea Glass—and choose the switch that aligns best with your typing needs.
