KTT Hyacinth vs. SP-Star Polaris Gray
An in-depth look at the KTT Hyacinth and the SP-Star Polaris Gray switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, two popular options to consider are the KTT Hyacinth and the SP-Star Polaris Gray. The Hyacinth stands out for its unique design choice of a 3.5mm travel distance, aimed at avoiding the hard bottoming-out experience often found with longer stemmed switches. This decision demonstrates a commitment to finding the perfect balance between tactile feedback, auditory experience, and user comfort. On the other hand, the Polaris Gray is highly regarded for those who prefer a bouncy typing experience. With a clean and clacky sound profile, these switches offer a different typing sensation and are categorized as low-pitched, neutral, mild, thocky, and polished. While these general pointers may help you make an initial decision, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for your needs.

Housing materials
The KTT Hyacinth and the SP-Star Polaris Gray share similar housing materials in their polycarbonate top housing. Both switches utilize this material to create a sharper, higher-pitched, and crisper sound profile. Polycarbonate is known for its stiffness, which leads to a clearer and more resonant sound. Additionally, both switches benefit from the translucency of polycarbonate, making it an excellent choice for RGB lighting enthusiasts. Therefore, users can expect similar results in terms of sound and aesthetics when using either switch's polycarbonate top housing.
However, the key point of distinction lies in the bottom housing material. The Hyacinth features a nylon bottom housing, renowned for producing a deeper and fuller sound profile. The softness of nylon allows it to absorb more sound, resulting in a duller and rounder sound. On the other hand, the Polaris Gray utilizes a polycarbonate bottom housing, which mirrors the traits of its top housing. This translates to a sharper, higher-pitched, and crisper sound profile in both the press and release of the switch.
When it comes to the user experience, the choice of bottom housing material plays a significant role. Pressing down on the Hyacinth switch will evoke the qualities of the nylon bottom housing, significantly impacting the bottom-out sound and feel. In contrast, the top housing, whether polycarbonate for both switches, will have more influence on the sound when you release a key. This distinction ensures that users can have a unique typing or gaming experience depending on their preference for a deeper and fuller sound (Hyacinth) or a sharper and crisper sound (Polaris Gray).
Weight
When comparing the actuation force and bottom out force of the KTT Hyacinth linear switch and the SP-Star Polaris Gray linear switch, there are both similarities and differences to consider. The Hyacinth has an actuation force of 45 grams and a bottom out force of 56 grams, which falls under the category of medium-light. On the other hand, the Polaris Gray's actuation force is unknown, but its bottom out force is 67 grams, making it medium-heavy.
For those who prefer a lighter typing experience, the Hyacinth switch would be the ideal choice as its actuation and bottom out forces are relatively lighter. This is especially beneficial for individuals who type for extended periods or engage in long gaming sessions, as the lighter weight allows for a smoother and less fatiguing typing experience.
On the other hand, the Polaris Gray switch caters to those who prefer a stronger push feel and a more substantial typing experience. With a higher bottom out force of 67 grams, this switch offers a more satisfying tactile feedback for individuals who enjoy a heavier typing sensation.
Although the actuation force of the Polaris Gray switch is not stated, it can be assumed that it is likely to be heavier than that of the Hyacinth, considering its higher bottom out force. Thus, users can expect a similar actuation force or even a slightly heavier force with the Polaris Gray switch.
Ultimately, the decision between these two switches depends on personal preference and typing style. If a lighter typing experience is desired, the Hyacinth switch is the lighter option. Conversely, for those seeking a heavier and more robust typing feel, the Polaris Gray switch provides a medium-heavy force for a satisfying keystroke.
Travel distance
The travel distance of the KTT Hyacinth linear switch is 3.5 mm, while the travel distance of the SP-Star Polaris Gray linear switch is 4 mm. In terms of travel distance, the Polaris Gray has a slightly longer distance compared to the Hyacinth. 4.0 mm is considered a more traditional travel distance, providing a balance between responsiveness and depth. On the other hand, the Hyacinth's 3.5 mm travel distance is on the shorter side, appealing to gamers who prioritize faster response times. While the Hyacinth offers a more responsive experience, some individuals may find the shorter travel distance to feel too abrupt. For those who prefer a more substantial key press, the Polaris Gray's longer travel distance would be the preferable option. Ultimately, the choice between the two switches depends on personal preference and the desired level of responsiveness or depth.

Typing experience
In terms of sound, the KTT Hyacinth is known for its neutral sound profile, which means it has a moderate sound profile and actuation force requirement. This makes it suitable for most purposes, whether you are a beginner or advanced user and whether you plan to use it at home or work. On the other hand, the SP-Star Polaris Gray has a low-pitched sound profile, which gives it a more bass-heavy and mellow tone compared to higher-pitched switches. Additionally, it is also described as neutral and thocky, producing a deep, rich, and satisfying sound when pressed and released. It is important to note that the sound of the switch can also be influenced by other factors such as the keyboard board and keycaps used.
When it comes to feel, the KTT Hyacinth is described as silky, offering an exceptionally smooth typing experience. These switches enhance the overall smoothness of the typing feel and minimize resistance when pressing and releasing keys. Additionally, they are also described as subtle, which means they have a gentle resistance that is not feather-like but still maintains a light typing feel. The sound signature of these switches is not resonant, making them suitable for shared spaces. On the other hand, the SP-Star Polaris Gray is described as mild, offering a more gentle typing experience compared to switches with more pronounced characteristics. Its qualities stand in a safe middle-ground zone that is approachable to most users. Furthermore, it is also described as polished, indicating that it has a smooth and refined finish, resulting in a sleek typing experience. This can be attributed to the materials used and/or factory lubing, which provide reduced friction and smooth key travel.
In conclusion, the KTT Hyacinth and SP-Star Polaris Gray switches have distinct subjective qualities in terms of sound and feel. The Hyacinth offers a neutral sound profile with a moderate actuation force requirement and a silky and subtle typing feel. On the other hand, the Polaris Gray provides a low-pitched sound profile, giving it a more bass-heavy and mellow tone, as well as a mild and polished typing feel. These differences make them suitable for different preferences and purposes. However, if you are seeking similar results, such as a moderate sound profile and a smooth typing experience, you can expect comparable qualities from both switches. Ultimately, the choice between the two will rely on your personal preferences and the specific experience you are looking to achieve.
Conclusion
In closing, if you are looking for a medium-light switch with a focus on balance between tactile feedback, auditory experience, and user comfort, the KTT Hyacinth linear switch is a great choice. With its 3.5mm travel distance and single-stage elongated spring, you can expect a consistent force curve and a smooth typing experience. The sound profile of the Hyacinth is described as neutral, making it suitable for various purposes and environments.
