KTT Hyacinth vs. Gazzew U4T

An in-depth look at the KTT Hyacinth and the Gazzew U4T switches—which one is the best fit for you?

Overview

The KTT Hyacinth and the Gazzew U4T are two mechanical keyboard switches that offer distinct features and benefits. The Hyacinth is a linear switch that stands out for its design choice of a 3.5mm travel distance. This decision was made to ensure a smooth typing experience without the common issue of a hard bottoming-out feel. The Hyacinth also deviates from the norm by using a single-stage elongated spring instead of the dual-stage elongated springs commonly found in other switches. This choice provides a more consistent force curve and adds to the overall user comfort. On the other hand, the Gazzew U4Ts are tactile switches that provide a harmonious fusion of thockiness and sharp tactility. The distinctive bassy 'thock' sound profile, paired with the assertive tactile feedback, ensures that every keystroke delivers both auditory and tactile satisfaction. While these general pointers give you an idea of what each switch offers, let's dive in a bit deeper beyond generalities so you can best decide on the perfect switch for you.

Housing materials

The housing materials of the KTT Hyacinth and the Gazzew U4T switches have distinct differences that contribute to the overall sound profile of each switch. The Hyacinth utilizes a polycarbonate top housing, which results in a sharper, higher-pitched, and crisper sound. The stiffer nature of polycarbonate enhances resonance and clarity, making it an excellent choice for those who prioritize a clear and resonant sound profile. In terms of aesthetics, its translucency makes it ideal for showcasing RGB lighting. On the other hand, the U4T's proprietary Gazzew blend top housing, also known as "boba plastic," provides a rich and deep sound profile due to its softness.

When it comes to the bottom housing, the Hyacinth employs a nylon material known for eliciting a deeper and fuller sound profile. Compared to harder plastics, nylon absorbs more sound, resulting in a duller and rounder sound. This classic switch housing material is favored for its ability to create a satisfying acoustic experience. Similarly, the U4T incorporates the proprietary Gazzew blend bottom housing, which shares characteristics with its top housing. This "boba plastic" also delivers a rich and deep sound profile due to its softness. Both nylon and the Gazzew blend contribute to creating switches that emphasize a tactile and pleasing sound output.

While the two switches have different housing materials, it's important to note that the qualities of these materials are split between the top and bottom of the switch. When pressing down on either switch, the bottom housing's impact on the bottom-out sound and feel will be more noticeable. Conversely, the top housing will have a greater influence on the sound produced when releasing a key. Despite these differences, both the Hyacinth and the U4T offer unique and enjoyable acoustic experiences. Whether it's the sharp and crisp sound of the Hyacinth's polycarbonate or the rich depth provided by the Gazzew blend, users can expect satisfying results from these housing materials.

Weight

When comparing the actuation force and bottom out force of the KTT Hyacinth linear switch and the Gazzew U4T tactile switch, there are some notable differences to consider. The Hyacinth has an actuation force of 45 grams, while the U4T's actuation force is unknown. In terms of bottom out force, the Hyacinth requires 56 grams of force, while the U4T requires 62 grams. This makes the Hyacinth lighter in both actuation and bottom out force compared to the U4T, which falls within the medium range.

For those who prefer a lighter typing experience and want to be able to type for extended periods, the Hyacinth may be the better choice. Its lower actuation and bottom out forces allow for smoother and faster keystrokes. On the other hand, if someone prefers a more substantial typing feel and enjoys a stronger push, the U4T would provide a more satisfying tactile experience.

It is important to note that although the actuation force of the U4T is unknown, it can be inferred that it may require a heavier force based on its higher bottom out force compared to the Hyacinth. However, without specific information on the actuation force, it is difficult to make a definitive comparison between the two switches.

Overall, the decision between the Hyacinth and U4T switches should be based on personal preference. Factors such as desired typing experience, duration of usage, and individual finger strength should be taken into consideration when choosing between these switches.

Travel distance

When comparing the travel distance of the KTT Hyacinth linear switch and the Gazzew U4T tactile switch, it is evident that they have different distances. The Hyacinth has a travel distance of 3.5 mm, while the U4T has a slightly longer travel distance of 4 mm. In terms of traditional travel distances, 4.0 mm is considered the norm, while 3.0 mm is regarded as the shallowest. However, with the growing popularity of gaming, shorter travel distances are becoming more prevalent, as they offer faster response times. Therefore, if you prioritize a quicker and more responsive typing experience, the Hyacinth with its shorter travel distance would be a suitable choice. On the other hand, if you prefer a more substantial and deeper keystroke, the U4T with its longer travel distance might be more satisfying. Ultimately, the choice between the two switches depends on individual preference and typing style.
