Akko V3 Crystal Pro vs. HMX FJ400
An in-depth look at the Akko V3 Crystal Pro and the HMX FJ400 switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, enthusiasts often find themselves weighing the distinct characteristics of various options, such as the Akko V3 Crystal Pro and the HMX FJ400, both of which are linear switches designed to enhance the typing experience. The V3 Crystal Pro is revered for its fully polycarbonate construction, which not only contributes to its unique bright and chirpy sound profile but also ensures a silky smooth typing experience that many typists find appealing. This switch is categorized as 'Bouncy,' 'Chirpy,' and 'Polished,' making it an excellent choice for those who seek auditory satisfaction alongside tactile comfort. On the other hand, the HMX FJ400 is positioned as a balanced option within the HMX Film switch lineup, appealing to users who prefer a harmonious sound profile without extremes, although its specific categories are less defined. With the Crystal Pro's lively auditory feedback and the FJ400's versatility, both switches present compelling arguments for why a typist might lean toward one over the other. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Akko V3 Crystal Pro and the HMX FJ400 utilize distinct materials for their housing, which fundamentally shapes their overall sound profiles and tactile characteristics. The V3 Crystal Pro features a polycarbonate top housing, known for producing a sharper, higher-pitched sound. Its stiffer nature contributes to a more resonant audio experience, making it particularly effective for RGB lighting applications due to its translucency. In contrast, the FJ400 incorporates POM (Polyoxymethylene) for its top housing, resulting in a unique sound profile that leans towards a deeper, more muted timbre. This difference means that while the V3 Crystal Pro excels in clarity and brightness, the FJ400 offers a sound that is rich and fuller, catering to distinct user preferences in tactile feedback.
When we examine the bottom housings, further contrasts emerge. The V3 Crystal Pro also utilizes polycarbonate, which aligns its bottom housing sound profile with that of its top housing, promoting a cohesive and bright auditory experience. Conversely, the FJ400 features a nylon bottom housing, which introduces additional depth and warmth to the switch’s output. Nylon's softer nature absorbs sound more effectively, resulting in a rounder and more subdued auditory impact when keys are bottomed out. This distinction highlights how even with similar materials in the top housing, the variations in the bottom materials lead to uniquely different sound characteristics for each switch.
Despite the differences in housing materials, achieving a satisfactory typing experience might hinge on personal preference rather than inherent superiority. Both switches can effectively fulfill users’ needs depending on the desired sound profile and tactile feedback. For instance, users who appreciate a crisp sound might favor the V3 Crystal Pro, while those who prefer a deeper acoustic experience may gravitate towards the FJ400. Ultimately, while each switch produces distinct auditory qualities due to their differing materials, they could still deliver comparable results based on keyboard and user interaction. Different users can find satisfaction in the unique characteristics that each switch provides, leading to a personalized typing experience that meets individual preferences.
Weight
The Akko V3 Crystal Pro linear switch and the HMX FJ400 linear switch both fall into the medium weight category, but they exhibit some differences in their actuation and bottom out forces. The V3 Crystal Pro has an actuation force of 48 grams and a bottom out force of 60 grams, making it slightly lighter to actuate, which can be beneficial for extended typing sessions or gaming marathons. In contrast, the FJ400 requires a slightly higher actuation force of 50 grams but has a lower bottom out force of 58 grams. This means that while the FJ400 feels a bit stronger initially when pressing any key, it allows for a quicker release once pressed all the way down. Thus, the V3 Crystal Pro is better suited for users who prefer a lighter touch, while the FJ400 provides a heftier feel, which might attract those who enjoy a solid typing experience. Overall, both switches offer unique characteristics, and users can choose according to their preferences for weight and feel.
Travel distance
Both the Akko V3 Crystal Pro linear switch and the HMX FJ400 linear switch have the same travel distance of 3.8 mm, meaning that pressing down on a key with either switch will yield a similar feel and depth of engagement. Since both switches share this equal travel distance, users can expect a consistent experience when typing or gaming, regardless of which switch they choose. This similarity in travel distance suggests that responsiveness and key actuation will be very comparable, making both options viable choices for those seeking linear switches.

Typing experience
The Akko V3 Crystal Pro linear switch produces a bright and chirpy sound signature, characterized by a unique acoustic quality that offers a little squeak when pressed. This distinct sound profile is largely attributed to its fully polycarbonate construction, which enhances the overall auditory experience. Users can expect the V3 Crystal Pro to deliver a lively and engaging sound, making each keystroke feel more pronounced. In contrast, the HMX FJ400 linear switch provides a more balanced sound profile, but details regarding its specific acoustic qualities remain unknown. However, it's important to note that the sound a switch produces can also be influenced greatly by factors such as the choice of keyboard and keycaps used.
When it comes to feel, the V3 Crystal Pro stands out with its bouncy and polished characteristics. The bouncy nature of this switch provides a spring-like feedback sensation, giving each key press a lively and responsive feel that many typists find enjoyable. Furthermore, the polished finish contributes to a sleek typing experience, resulting in reduced friction and smooth key travel thanks to the materials used and factory lubing. Unfortunately, little is known about the feel of the HMX FJ400 switch, making direct comparisons challenging.
In summary, the Akko V3 Crystal Pro linear switch is celebrated for its bright, chirpy sound and its bouncy, polished typing feel, while the HMX FJ400 linear switch remains somewhat of an enigma in terms of both sound and feel. Those searching for a distinct auditory experience with a lively typing sensation may lean towards the V3 Crystal Pro, whereas the FJ400 offers a more understated sound profile that may appeal to those preferring a balanced approach. Ultimately, both switches cater to different preferences, and the choice will depend on individual typing style and desired sensory feedback.
Conclusion
To conclude, choosing between the Akko V3 Crystal Pro and the HMX FJ400 linear switches ultimately depends on your personal preferences and usage scenarios. If you value a lively and engaging typing experience, the V3 Crystal Pro might be the ideal choice for you, given its bouncy feel and polished design that ensures smooth key travel. The chirpy sound profile adds a playful twist, making it suitable for those who enjoy a more dynamic auditory feedback while typing or gaming. On the other hand, if you’re looking for a balanced option that blends performance with a more subdued sound signature, the FJ400 could be your go-to switch. Its slightly lower bottom out force provides a similar feel to the V3, but without the distinct chirpiness, offering a more versatile experience that suits both casual typing and prolonged work sessions. Ultimately, your choice will hinge on whether you prioritize an engaging tactile experience or a balanced, quieter typing environment.
