KTT Hyacinth vs. Gazzew U4Tx

An in-depth look at the KTT Hyacinth and the Gazzew U4Tx switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, there are a multitude of options to choose from, each with its own unique characteristics and benefits. Two switches that stand out among the rest are the KTT Hyacinth and the Gazzew U4Tx. The Hyacinth is a linear switch that prioritizes user comfort and tactile feedback. By opting for a 3.5mm travel distance, it eliminates the hard bottoming-out experience commonly associated with longer-stem switches. Additionally, the Hyacinth's choice of a single-stage elongated spring ensures a consistent force curve. On the other hand, the U4Tx is a tactile switch that combines the best of both worlds. It offers a refined sound profile with a deep, resonant "thock" when bottoming out and a whisper-quiet topping out sound. The U4Tx provides a sharp and satisfying tactile bump, delivering a luxurious typing experience. While these general pointers can certainly help in making a decision, diving deeper into the intricacies of these switches will ultimately allow you to choose the best one for your specific needs.

Housing materials

The housing materials of the KTT Hyacinth and the Gazzew U4Tx have distinct differences that affect their sound profiles. The Hyacinth's polycarbonate top housing offers a sharper and crisper sound due to its stiffer nature. This results in a higher-pitched sound that works well with RGB lighting. In contrast, the U4Tx's proprietary Gazzew blend top housing, often called "boba plastic," delivers a rich and deep sound profile. Its softness contributes to a more resonant and full-bodied tone. While the two materials differ in terms of sound characteristics, both can provide satisfying results.

In terms of bottom housing, the Hyacinth features a nylon material that creates a deeper and fuller sound. The softness of nylon allows it to absorb more sound, resulting in a duller and rounder tone. On the other hand, the U4Tx's Gazzew blend bottom housing shares the same "boba plastic" material as its top housing, ensuring consistency in sound profile. The soft nature of this proprietary blend contributes to a rich and deep sound experience. Although both bottom housings deliver different sound profiles, they both aim to enhance the overall typing experience.

Both the top and bottom housing materials play a crucial role in determining the sound generated when using these switches. When pressing down on a switch, the qualities of the bottom housing become prominent, influencing the sound and feel at the moment of bottoming out. Conversely, the top housing comes into play when releasing a key, shaping the sound that is produced. Each material's unique characteristics contribute to the overall sound profile, allowing users to choose based on their personal preferences. While the specific materials may differ between the Hyacinth and the U4Tx, the impact on the sound experience remains an essential factor to consider.

Weight

When comparing the actuation force and bottom out force of the KTT Hyacinth linear switch and the Gazzew U4Tx tactile switch, there are noticeable differences in terms of weight. The Hyacinth exhibits a medium-light actuation force of 45 grams and a bottom out force of 56 grams. In contrast, the U4Tx's actuation force is not available, but its bottom out force is 65 grams, placing it in the medium-heavy category.

For those who prefer a lighter typing experience, the Hyacinth would be a suitable choice as its actuation force is lighter than its bottom out force. This lighter weight allows for longer typing sessions without causing fatigue. On the other hand, individuals who appreciate a more substantial push feel during typing may opt for the U4Tx. Its heavier bottom out force provides a satisfying tactile feedback and a sense of solidity while typing.

It is important to note that, in terms of actuation force, we are unable to directly compare the two switches as the specific value for the U4Tx is not provided. However, it can be inferred that the Hyacinth would likely have a lighter actuation force compared to the U4Tx due to its overall lighter weight classification. Therefore, if one desires a similar actuation force as the Hyacinth, it would be advisable to select a U4Tx variant with a similar or lighter weight classification.

Considering the factors of weight, the Hyacinth is lighter, making it suitable for extended typing sessions or gaming marathons. Conversely, the U4Tx is heavier, providing a stronger push feel for those seeking a more substantial typing experience. Ultimately, the choice between these two switches will depend on individual preferences and the desired typing sensation one is seeking.

Travel distance

The KTT Hyacinth linear switch and the Gazzew U4Tx tactile switch have slightly different travel distances. The Hyacinth has a travel distance of 3.5 mm, while the U4Tx has a travel distance of 3.6 mm. Although the difference may seem minimal, it may be noticeable to those with a sensitive touch. The Hyacinth has a slightly shallower travel distance, which can be advantageous for gamers or individuals looking for faster response times. On the other hand, the U4Tx offers a slightly longer travel distance, which can provide a more satisfying and deep keystroke experience for those who prefer it. Ultimately, the choice between the two switches depends on personal preference and the desired feel when typing or gaming. However, it is important to note that both switches fall within the range of shorter travel distances, offering similar results in terms of overall key press sensation.
