HMX Gravel vs. Kailh BCP

Overview

When comparing mechanical keyboard switches, the HMX Gravel and the Kailh BCP emerge as two noteworthy options, each catering to distinct user preferences. The Gravel is celebrated for its exceptional smoothness and refined typing feel, providing a medium-light actuation force that enables a responsive and nearly effortless experience. This makes it an appealing choice for those seeking a seamless typing experience without sacrificing tactile feedback. In contrast, the Kailh BCP switches put a creative spin on the classic Black Cherry Pies, boasting a creamy and bouncy texture with an engaging poppy sound profile. This switch is ideal for individuals who appreciate a more dynamic auditory experience while typing. While both switches are linear and offer unique benefits, understanding their individual characteristics is crucial for users to make informed choices. 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 HMX Gravel and Kailh BCP switches, the primary distinction lies in their top housing materials. The Gravel utilizes polycarbonate for its top housing, which is known for producing a sharper, higher-pitched, and crisper sound profile. The inherent stiffness of polycarbonate contributes to this distinctive acoustic signature, enhancing clarity and resonance, which can be particularly beneficial for users seeking a more defined auditory experience. Moreover, the translucency of polycarbonate allows for effective RGB lighting, providing an aesthetically appealing glow that complements the switch’s performance.

On the other hand, the Kailh BCP features a nylon top housing, which contrasts starkly with the Gravel's polycarbonate. Nylon is celebrated for its sound-absorbing properties, yielding a deeper and fuller sound profile. This material's softer nature results in a more muffled auditory experience compared to the Gravel, leading to a rounder and less pronounced sound. Users who prefer a more subdued and warmer typing experience may find the BCP's nylon housing to be more to their liking. The choice between polycarbonate and nylon in the top housing ultimately influences the character of the switch, catering to different preferences in tactile and auditory feedback.

Interestingly, both switches share nylon for their bottom housing, which aligns them closely in acoustic performance when it comes to the key's bottom-out sound. This similarity means that, regardless of the differences in their top housing materials, users can expect a comparably full and rounded sound profile from both switches upon bottoming out. This dual use of nylon ensures that both the HMX Gravel and Kailh BCP offer a satisfying tactile feel when pressed, while their distinct top housings create divergent experiences on release. Consequently, users can achieve unique auditory experiences based on which switch they prefer, helping to inform their choice based on personal sound and feel preferences.

Weight

When comparing the HMX Gravel linear switch and the Kailh BCP linear switch, there are notable differences in their actuation and bottom out forces. The Gravel switch features a lighter actuation force of 45 grams and a bottom out force of 50 grams, making it more suitable for users who prefer a softer touch for prolonged typing or gaming sessions. In contrast, the Kailh BCP switch has a heavier actuation force of 52 grams and a bottom out force of 63.5 grams, appealing to those who enjoy a firmer push feel for a more substantial typing experience. Therefore, the Gravel is the lighter option, while the BCP is the heavier choice. The difference in force requirements means that users of the Gravel switch can expect a gentler tactile experience, while those opting for the BCP will have to apply more force, resulting in a stronger and more tactile feedback.

Travel distance

The HMX Gravel linear switch and the Kailh BCP linear switch both exhibit the same travel distance of 3.5 mm, indicating that users can expect a similar feel when pressing down on either switch. Since both switches travel the same distance from the top to the bottom, their performance in terms of travel distance will yield comparable results, making them equally suitable for those who prefer a consistent keypress experience. This equal travel distance may appeal to users looking for uniformity in their typing or gaming activities.

Typing experience

In terms of sound, the HMX Gravel linear switch is characterized by its smooth and quiet operation, making it an excellent choice for those who prefer a more muted auditory experience while typing. This allows for an almost serene atmosphere, enhancing the focus of the user. In contrast, the Kailh BCP linear switch stands out with its poppy and clacky sound profile, which can be more engaging and satisfying for those who enjoy a lively acoustic feedback as they type. While the sound personality of these switches differs significantly, it's important to remember that sound perception can also vary based on the keyboard build and keycap material used.

When it comes to feel, the Gravel switch offers a notably smooth and refined typing experience, aided by its medium-light actuation force that makes it responsive and effortless to press. This can create a sensation of fluidity that many typists appreciate. On the other hand, the Kailh BCP switch introduces a creamy, viscous, elastic, and bouncy feel, offering a tactile delight that is both unique and enjoyable. The difference in their physical sensations creates distinct typing experiences that cater to different preferences; one leans towards a smooth ride while the other emphasizes a bouncier, more tactile feedback.

In conclusion, while both the HMX Gravel and Kailh BCP linear switches present unique qualities in sound and feel, they cater to different user preferences. The Gravel excels in a quieter, smoother experience, while the BCP provides a more expressive sound with a delightful bounce. Selecting between the two ultimately comes down to whether you prefer a serene typing experience or an engaging, energetic one. Regardless of choice, enthusiasts can expect a satisfying experience that aligns with their desired keyboard feel.

Conclusion

To wrap up, when selecting between the HMX Gravel linear switch and the Kailh BCP linear switch, consider your personal preferences and typing needs. If you favor a smoother and lighter typing experience that is exceptionally refined, the Gravel switch is an excellent choice. Its 50-gram bottom-out force allows for quick, effortless keystrokes, making it ideal for long typing sessions or fast-paced gaming where responsiveness is key. Conversely, if you prefer a firmer feel with a touch of character in your typing, the BCP switch, with its 63.5-gram bottom-out force, might suit you better. Its distinctive poppy sound and bouncy tactile feedback can bring a lively essence to your writing or gaming. Ultimately, choose the Gravel for a silky smooth experience or the BCP for a more dynamic, engaging typing journey.
