Outemu Crystal vs. Kailh Plum
An in-depth look at the Outemu Crystal and the Kailh Plum switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, two popular options to consider are the Outemu Crystal and the Kailh Plum. The Crystal is a linear switch, known for its unique typing experience of medium-light weight and a fairly elastic feel. It offers a neutral sound profile while typing, making it a suitable choice for those who prefer a quieter keyboard. On the other hand, the Plum is a tactile switch that stands out for its hefty feel without a pronounced tactile bump. Unlike many other tactile switches, weightiness and tactility are not directly correlated with the Plum. It also provides a neutral and enjoyable sound profile. However, let's dive in a bit deeper beyond these generalities so that you can make an informed decision on the best switch for your needs.

Housing materials
The housing materials of the Outemu Crystal and the Kailh Plum switches share many similarities. Both switches feature a polycarbonate top housing, which creates a sharper, higher-pitched, and crisper sound profile. This is because polycarbonate is a relatively stiffer plastic, resulting in a clear and resonant sound. Additionally, the translucency of polycarbonate makes it ideal for switches with RGB lighting. Therefore, both the Crystal and the Plum switches will provide similar results in terms of sound and aesthetics due to their shared polycarbonate top housing material.
However, the differences arise when we look at the bottom housing of these switches. The Crystal switch utilizes a polycarbonate bottom housing, which complements the characteristics of the top housing. The stiffer nature of polycarbonate in the bottom housing enhances the overall sound profile, allowing for a more defined and impactful bottom-out sound and feel. On the other hand, the Plum switch has a nylon bottom housing. Nylon is known for its softer composition, which absorbs more sound compared to harder plastics. As a result, the Plum switch produces a deeper and fuller sound profile, creating a somewhat duller and rounder sound.
The distinction between the two switches becomes apparent when considering the impact of each housing material. While the bottom housing influences the bottom-out sound and feel, the top housing has a greater effect on the sound when releasing a key. Therefore, the Crystal switch with its polycarbonate bottom housing will deliver a crisper and more pronounced bottom-out sound, while the Plum switch with its nylon bottom housing will provide a deeper and fuller sound profile. Overall, both switches offer unique audio experiences based on the composition of their respective housing materials.
Weight
When comparing the actuation force and bottom out force of the Outemu Crystal linear switch and the Kailh Plum tactile switch, we can see some key differences. The Crystal has an actuation force of 45 grams, while the Plum's actuation force is not specified. However, in terms of bottom out force, the Crystal requires 55 grams, while the Plum is significantly heavier at 70 grams.
Considering weight as a factor, those who prefer a lighter typing experience may lean towards the Crystal switch. Its actuation force of 45 grams allows for a smoother and lighter keystroke, making it ideal for longer typing sessions or extended gaming sessions. On the other hand, for individuals seeking a stronger and more substantial push feel, the Plum switch might be the preferred choice. With its higher bottom out force of 70 grams, it provides a more tactile and forceful typing experience.
It is worth noting that if a lighter or heavier force is desired, users can still achieve similar results by adjusting their typing technique. For instance, if one prefers a lighter force but chooses the Plum switch, they can type more gently to reduce the perceived heaviness. Similarly, if someone prefers a heavier force but opts for the Crystal switch, they can type with more force to compensate for the lighter actuation and bottom out forces.
In conclusion, the Outemu Crystal linear switch offers a medium-light typing experience with an actuation force of 45 grams and a bottom out force of 55 grams. On the other hand, the Kailh Plum tactile switch provides a medium-heavy feel with an unknown actuation force and a bottom out force of 70 grams. The choice between these switches ultimately depends on the individual's preference for a lighter or heavier typing experience.
Travel distance
When comparing the travel distance of the Outemu Crystal linear switch and the Kailh Plum tactile switch, it is clear that the Crystal has a longer distance of 4.0mm, while the Plum has a slightly shorter distance of 3.6mm. The 4.0mm travel distance of the Crystal is more in line with traditional switch distances, providing a deeper and more substantial feel when pressing down on the keys. On the other hand, the 3.6mm travel distance of the Plum is slightly shallower, which may appeal to gamers who prioritize quicker response times. While both options offer a satisfactory travel distance, the Crystal provides a touch more depth, resulting in a more robust typing experience.

Typing experience
When it comes to sound, the Outemu Crystal linear switch has a unique acoustic signature, described as "chirpy". This means that the switches have a slight squeak to them, setting them apart from other switches. Additionally, they have a high-pitched sound, producing a sharp and crisp sound when pressed. If you prefer a switch with a more rich and bassy sound profile, the Crystal may not be the best choice for you. On the other hand, the Kailh Plum tactile switch has a neutral sound profile that is enjoyable. It doesn't have any specific sound characteristics mentioned, but it is described as suitable for most intents and purposes. However, it's important to note that the sound of a switch can also be influenced by other factors such as the keyboard board and keycaps used.
When it comes to feel, the Outemu Crystal linear switch is described as having a polished finish. This results in a smooth and refined typing experience, with reduced friction and smooth key travel. The Crystal switches provide a sleek typing experience due to the materials used and/or factory lubing. On the other hand, the Kailh Plum tactile switch offers a mild typing experience. It is described as a more gentle switch compared to those with more pronounced characteristics. The sound and feel of the Plum switch are approachable to most, as it falls within a safe and middle-ground zone. Additionally, the Plum switch is described as a stepped switch, meaning it has a two-stage feel. Unlike hypertactile switches which have a single big bump, the stepped switches have some pre-travel and/or post-travel, resulting in a milder tactile experience.
In conclusion, the Outemu Crystal linear switch and the Kailh Plum tactile switch have different subjective qualities in terms of sound and feel. The Crystal offers a chirpy and high-pitched sound with a polished and smooth feel, providing a unique linear typing experience. On the other hand, the Plum switch has a neutral sound profile that is enjoyable and offers a more mild and gentle typing experience, being approachable to most users. Both switches have their own distinct characteristics, so the choice between them would depend on personal preferences regarding sound and feel. However, if you prefer a similar typing experience to the Crystal but with a different sound profile, the Plum switch could provide a comparable result.
Conclusion
To sum up, the Outemu Crystal linear switch would be a great choice if you are looking for a unique, linear typing experience with a medium-light weight. These switches have a fairly elastic feel and offer a neutral sound profile when typing. On the other hand, if you prefer a heavier switch with a tactile feel, the Kailh Plum tactile switch would be more suitable. These switches feel quite hefty but don't have a huge tactile bump, making them incredibly unique. Their sound profile is neutral and enjoyable. Ultimately, the choice between these two switches depends on your preference for weight and tactility. If you prefer a lighter, linear switch, go for the Crystal. If you prefer a heavier, tactile switch, the Plum would be a better fit. Both switches offer their own advantages and can provide an enjoyable typing experience.
