TTC Silent Frozen (V2) vs. HMX SU
An in-depth look at the TTC Silent Frozen (V2) and the HMX SU switches—which one is the best fit for you?
Overview
When it comes to selecting the right mechanical keyboard switch, two noteworthy options are the TTC Silent Frozen (V2) and the HMX SU, both of which offer linear characteristics that cater to different preferences. The Silent Frozen (V2) stands out for its extremely quiet sound profile, making it an excellent choice for those who prioritize a serene typing experience without the distraction of noise. Its smooth, pillowy feel adds an element of comfort, enhancing the overall user experience for long typing sessions. On the other hand, the HMX SU, with its full PA12 housing and T5 stem, provides a subtle yet relatively deep sound profile, appealing to users looking for a more unique auditory feedback while maintaining a smooth typing experience. While both switches offer a linear feel, the Silent Frozen (V2) excels in its quiet performance and softness, whereas the HMX SU provides a balance of deeper sound with solid construction. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The TTC Silent Frozen (V2) and HMX SU switches distinguish themselves through their choice of housing materials, each leading to different acoustic profiles. The Silent Frozen (V2) employs polycarbonate for both its top and bottom housings. This material is known for its stiffness, resulting in a sharper and crisper sound. The translucency of polycarbonate not only contributes to a clearer sound but also enhances RGB lighting effects, making the switch visually appealing. In contrast, the HMX SU utilizes nylon for both its top and bottom housings, which fosters a deeper, fuller sound profile due to the material's softer nature. Nylon is adept at dampening sound, leading to a rounder acoustic experience that contrasts sharply with the sharpness of polycarbonate.
When considering the bottom and top housing contributions, the design of each switch further emphasizes their material differences. For the TTC Silent Frozen (V2), the polycarbonate bottom housing plays a significant role in defining the switch's bottom-out sound, creating a resonant experience. Conversely, the nylon bottom housing of the HMX SU influences the switch's response by providing a softer and more muted sound, ideal for those who prefer a quieter typing experience. The top housing also has critical implications; while the polycarbonate top enhances sounds produced upon releasing the key, the nylon top of the HMX SU contributes a subdued tone during key release, cultivating a typing experience that feels distinct yet cohesive.
Ultimately, while the TTC Silent Frozen (V2) and HMX SU switches utilize different housing materials, both can achieve gratifying acoustic effects that cater to varied preferences. If one enjoys a clearer, more vibrant sound, the polycarbonate materials of the Silent Frozen (V2) will provide that experience, while those who lean towards a softer, more rounded sound will find satisfaction in the nylon constructions of the HMX SU. If someone seeks similar tactile satisfaction and sound response characteristics regardless of housing material, they might find ways to tune their typing experience through switch modifications, such as adding dampening materials or using keycap designs that suit their acoustic preferences. Thus, while the housing materials differ, similar results can be achieved through customization and careful consideration of the typing environment.
Weight
When comparing the TTC Silent Frozen (V2) linear switch to the HMX SU linear switch, notable differences arise in their actuation and bottom out forces. The Silent Frozen (V2) has a lighter actuation force of 39 grams and a bottom out force of 43 grams, making it more suitable for users who prefer a softer touch for extended typing sessions. In contrast, the HMX SU linear switch features a heavier actuation force of 45 grams and a bottom out force of 50 grams, providing a more substantial feel that some typists might find more satisfying. Consequently, those who seek a lighter switch for comfort during long use should opt for the Silent Frozen (V2), while those who favor a more pronounced key press could prefer the HMX SU. Overall, while both switches are classified as light, the Silent Frozen (V2) is the lighter of the two options.
Travel distance
When comparing the travel distances of the TTC Silent Frozen (V2) linear switch and the HMX SU linear switch, we find that the Silent Frozen has a travel distance of 3.5 mm, while the HMX SU offers a slightly longer travel distance of 3.6 mm. This makes the Silent Frozen the shorter option, which may appeal to users seeking quicker responsiveness and faster key presses, particularly in gaming scenarios. On the other hand, the HMX SU, with its longer distance, may provide a more substantial feel and could be preferred by those who appreciate a tactile depth in their key presses. Overall, while both switches offer relatively similar travel distances, the subtle difference might influence the choice based on personal preferences for either speed or depth in keyboard feedback.

Typing experience
When it comes to sound, the TTC Silent Frozen (V2) switches are renowned for their extremely quiet profile, characterized by a thocky, low-pitched, and muted sound. This combination results in a deep, rich tone that is both satisfying and unobtrusive, making it ideal for environments where noise levels should be kept to a minimum. In contrast, the HMX SU linear switches have a subtle and relatively deep sound profile, although the specific nuances of their acoustic characteristics are less defined. Given that the sound output of mechanical switches can vary based on factors such as the keyboard configuration and keycap materials, both switches may achieve a similar level of quietness, particularly in setups that prioritize noise dampening.
Regarding the feel, the TTC Silent Frozen (V2) switches are celebrated for their creamy, buttery, and polished typing experience. They provide a smooth, effortless actuation that reduces finger strain, making them comfortable for long typing sessions. Descriptors such as feathery and subtle further emphasize their light tactile resistance, ensuring a refined but gentle experience. On the other hand, little is known about the feel of the HMX SU switches. This absence of information makes it difficult to gauge how they compare to the TTC Silent Frozen (V2) in terms of typing experience, but it is possible that users might appreciate a similarly smooth interaction depending on the specific design and materials employed.
In summary, while the TTC Silent Frozen (V2) switches offer a distinctive acoustic profile and a notably smooth feel ideal for quiet environments and prolonged use, the HMX SU linear switches present an undetermined but possibly deep and subtle sound experience, with limited information on their feel. Overall, if noise and smoothness are priorities for a newcomer, the TTC Silent Frozen (V2) presents a clear advantage; however, users may find satisfaction in either switch depending on their individual preferences and the acoustic characteristics of their setup.
Conclusion
To conclude, when choosing between the TTC Silent Frozen (V2) linear switch and the HMX SU linear switch, it's essential to consider your personal preferences regarding sound and feel, as well as the intended use of your keyboard. If you prioritize an exceptionally quiet typing experience with a soft, smooth feel, the Silent Frozen (V2) is an excellent choice, especially for environments like offices or shared spaces where noise could be disruptive. Its lighter bottom-out force of 43 grams makes it a great option for long typing sessions without causing finger fatigue, while the creamy, buttery sensation adds to its overall comfort. On the other hand, if you prefer a slightly heavier key press with a deeper sound profile, the HMX SU switch may be better suited for you. With a 50-gram bottom-out force, it delivers a more pronounced tactile feedback, which can enhance the typing experience for those who enjoy a bit more resistance while typing. Ultimately, your decision should hinge on whether you value whisper-quiet operation and lighter touch, or if you lean towards a fuller, slightly more substantial keystroke. Both switches have their distinct advantages, catering to different typing preferences and environments.
