Kailh BCP vs. Outemu Dustproof Blue

An in-depth look at the Kailh BCP and the Outemu Dustproof Blue switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, the choice often boils down to individual preferences in typing feel and sound feedback. The Kailh BCP, known for its smooth linear action, reimagines the iconic Black Cherry Pies (BCPs) with custom-molded switches that boast a creamy and elastic sensation while typing. Its operation is marked by a distinct pop and clack, making it an engaging choice for those who favor a tactile and lively experience without the distractions of disassembly hassles. On the other hand, the Outemu Dustproof Blue switch offers a more traditional clicky feedback, beloved by typists who appreciate the auditory confirmation of each keystroke. This switch's signature clicking sound is not only satisfying but also serves as a clear indicator of actuation, making it a top choice for those who thrive on the rhythm of their typing. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

When comparing the housing materials of the Kailh BCP and Outemu Dustproof Blue switches, a notable difference is found between the top housings. The Kailh BCP utilizes a nylon top housing, which is renowned for its ability to produce a deeper and fuller sound profile. This is largely attributed to the softness of nylon, a material that dampens sound more effectively than harder alternatives. In contrast, the Outemu Dustproof Blue features a polycarbonate top housing that contributes a sharper and crisper sound profile. The stiffer nature of polycarbonate enhances resonance, providing a more pronounced auditory feedback that many typists and gamers may prefer for its clarity. Aesthetically, the translucency of the polycarbonate allows RGB lighting to shine through, making it a popular choice for illuminated keyboards, while the nylon top does not offer the same visual effect.

In terms of bottom housing, both switches employ nylon, which leads to a uniformity in their acoustic performance in this aspect. Nylon's softer properties result in a sound that is again deep and full, creating a pleasant, cushioned bottom-out feel regardless of the switch type. The smoothness of the nylon utilized in both the Kailh BCP and the Dustproof Blue contributes to a similar tactile experience; users can expect a softer landing when they depress the keys due to the nylon's sound-absorbing characteristics. This similarity ensures that, in terms of bottom-out sound and feel, the two switches resonate closely, despite their differing top housing materials.

Ultimately, the combination of a nylon bottom housing with a nylon top in the Kailh BCP allows for a cohesive sound experience that enhances performance through deeper, warmer tones. Meanwhile, the Outemu Dustproof Blue’s mixed housing approach, featuring polycarbonate on top, yields a more contrasted auditory output with a brighter sound signature. However, the sonic qualities introduced by the nylon bottom housing help to soften the impact of the polycarbonate's sharper characteristics. Therefore, while users may perceive differences between the two switches based on their distinct top materials, the underlying nylon bottom housing ensures that both switches share a foundational acoustic warmth, illustrating how the combination of differing and similar materials can orchestrate a diverse yet harmonious typing experience.

Weight

When comparing the Kailh BCP linear switch and the Outemu Dustproof Blue clicky switch, there are notable differences and subtle similarities in their actuation and bottom out forces. The BCP switch requires an actuation force of 52 grams, while the Dustproof Blue has a slightly lighter actuation force of 50 grams, making it the more suitable option for users who prefer a lighter touch, especially during prolonged typing or gaming sessions. In terms of bottom out forces, the BCP reaches 63.5 grams, compared to the Dustproof Blue's 65 grams, indicating a firmer resistance when fully pressed down. Consequently, while both switches fall within the medium-heavy category, the Kailh BCP offers a marginally heavier feel compared to the Outemu switch's lighter overall actuation. Thus, for those who appreciate a stronger push, the BCP may provide a more satisfying experience, whereas the Dustproof Blue could appeal to typists seeking a softer touch.

Travel distance

The Kailh BCP linear switch features a travel distance of 3.5 mm, while the Outemu Dustproof Blue clicky switch has a slightly longer travel distance of 4 mm. This means that the BCP switch offers a more responsive feel, making it a suitable choice for gamers who prefer quicker actuation times. On the other hand, the Dustproof Blue's 4 mm travel distance may provide a more pronounced tactile experience, which some users find more satisfying, especially for typing or gaming that benefits from a deeper keypress. Therefore, if you're seeking a shorter travel distance for enhanced responsiveness, the Kailh BCP is the better option. Conversely, if you favor a deeper, more traditional feel, the Outemu Dustproof Blue would be the preferable choice.

Typing experience

In terms of sound, the Kailh BCP linear switch delivers a distinctly poppy and clacky sound profile that is both satisfying and expressive. This lively auditory feedback enhances the typing experience, making each keystroke feel impactful. On the other hand, the Outemu Dustproof Blue clicky switch falls into a similar category where, although specific sound characteristics haven't been outlined, clicky switches generally produce audible feedback that mimics traditional mechanical switch sounds. While the qualities may vary depending on the typing surface and keycap choice, one can expect a satisfying sound from both switches, although the BCP will be more uniquely defined in its sound profile.

When it comes to feel, the Kailh BCP switch offers a creamy, viscous, elastic, and bouncy sensation that enhances the typing experience, making each keypress feel responsive and robust. This tactile sensation is further amplified by the switch's linear design, which allows for smooth and uninterrupted keystrokes. Conversely, the Outemu Dustproof Blue clicky switch, being a clicky variant, is likely to provide a tactile bump during actuation, a distinct feature that offers a different typing experience. However, without specific information on the feel, it's difficult to accurately compare them. Nonetheless, both switches aim to deliver an agreeable tactile experience, tailored to their respective user preferences.

In conclusion, while the Kailh BCP linear switch is recognized for its delightful sound and superior tactile experience, the Outemu Dustproof Blue clicky switch is characterized by conventional clickiness. The notable differences in sound profile and feel between these switches can cater to varying preferences in typing style. Users looking for a lively, auditory experience matched with a plush feeling might gravitate toward the BCP, while those who enjoy tactile feedback from clicky switches may find the Outemu Dustproof Blue appealing. Understanding these nuances can provide newcomers with valuable insights into selecting the perfect switch for their mechanical keyboard setup.

Conclusion

To conclude, when deciding between the Kailh BCP linear switch and the Outemu Dustproof Blue clicky switch, your choice will largely depend on your personal preferences and typing style. If you prefer a smoother, quieter experience with a balanced tactile feedback, the Kailh BCP is an excellent option. It offers a unique, creamy feel and a bouncy response that can enhance your typing comfort, making it ideal for long writing sessions or coding. Furthermore, if you enjoy a more subdued auditory profile while still retaining a satisfying tactile sensation, the BCP is the way to go. Conversely, if you thrive on auditory feedback and enjoy the enthusiastic, clicky sound that typifies a more traditional typing experience, the Outemu Dustproof Blue should be your go-to switch. Its medium-heavy bottom-out force provides a satisfying heft, and the distinct click can enhance your typing rhythm, making it particularly appealing for those who enjoy the aural cues of their keystrokes. Ultimately, your decision should reflect whether you prioritize a smooth and quiet typing experience (Kailh BCP) or an engaging and audible interaction (Outemu Dustproof Blue).
