Switch Sound

MMD Princess V2 Tactile

The MMD Princess V2 Tactile is comparable to the Boba U4T in terms of sound. They have a similar sound profile, but the MMD Princess V2 Tactile has a slightly brighter and clackier bottom out and a bolder volume. The difference in materials used and the short travel distance could be a factor in why the MMD Princess V2 Tactile has a louder and higher pitched sound. The MMD Princess V2 Tactile has a very crisp tactile bump that creates an emphasized bottom out and a very poppy top out also due to the tactile bump on the upstroke. 

Here is a sound test of the MMD Princess V2 Tactile:

MMD Princess V2 Linear

The MMD Princess V2 Linear is a creamy sounding switch that falls comfortably in the mid-tones and borders both the lows and the highs. The bottom out has a hard and creamy sound signature while the top out has a soft and crispy sound signature. Its snappy sound profile could be due to the short travel distance and the creamy sound profile could be the result of the smooth and soft POM+PFTE stem material making contact with the hard PC top and bottom housing, producing notes in both the low and high ranges.

MMD Vivian

The MMD Vivian stands out as a thocky switch. It has a hard and creamy bottom out and a soft and dampened top out. The PUM bottom housing material helps create a deep tone but also a hard plastic-y sound profile. Overall, the combination of the PUM bottom housing and the soft modified UPE stem material produces a soft and thocky sound signature.

MMD Matcha Ice Cream V3

The MMD Matcha Ice Cream V3 has as a crisp and high-pitched clack. The bottom out is sharp and crisp while the top out is soft. While it feels glossy smooth to type on, there is some scratchiness in the sound in its stock form, however it is not noticeable during normal typing. The scratchiness is noticeably reduced when hand lubed, offering a smoother and more enjoyable typing experience. The MMD Matcha Ice Cream V3 has a satisfying clack that isn't obnoxiously loud, especially for light typists.

Switch Feel

MMD Princess V2 Tactile

The MMD Princess V2 Tactile has a pronounced tactile bump with a slight linear post-travel. It feels clean and snappy to type on with no noticeable scratch or stem wobble. I would describe the MMD Princess V2 Tactile as having a large, rounded uppercase "P" shaped tactile bump. It creates a very responsive bottom out where you can feel the tactility almost throughout the entirety of the keypress. The short travel distance could play a role in how responsive and snappy the MMD Princess V2 Tactile feels. The MMD Princess V2 Tactile feels very similar in terms of feel to the Boba U4T. They have a similar feeling bump and a similar feeling snappiness to each bottom out and top out thanks to their crisp tactile bumps.

MMD Princess V2 Linear

The MMD Princess V2 Linear falls right in the middle for typing feel as well as it did for sound. The factory lube feels smooth and consistent, providing a very comfortable typing experience without fatigue. The MMD Princess V2 Linear also feels very responsive due to a combination of its short travel distance and a dual-staged spring. The short travel distance helps with faster actuations on the downstroke and the dual-staged spring helps with the snappy responsiveness on the upstroke. 

MMD Vivian

The MMD Vivian feels as thocky as it sounds. The MMD Vivian is a great option for those who enjoy the feeling of thoroughly lubed switches. Its creamy typing feel could be due to the modified UPE stem material because of its softness. The modified UPE stem material provides a thocky and soft feeling typing experience. 

MMD Matcha Ice Cream V3

The MMD Matcha Ice Cream V3 feels glossy to type on. It has a smoothness similar to gliding on glass in contrast to a smoothness that traditional lubed switches have. Although on off center keypresses there are subtle notes of scratchiness. This could be due to their stem rail design that has the middle of the rail welled out so that only the edges of the stem rail made contact with the rails of the bottom housing. Less surface area in contact with each other would reduce the amount of friction and resistance. The scratchiness is noticeably reduced when hand lubed, offering a smoother and more enjoyable typing experience. The MMD Matcha Ice Cream V3 also has a short travel distance and a dual-staged spring like the MMD Princess V2 Linear, creating a similar responsive actuation and snappy upstroke. 

Additional Notes

The MMD Vivian has a LED diffuser for enthusiasts who enjoy displaying RGB or LED in their keyboard setup.

The MMD Matcha Ice Cream V3 has a non-traditional stem rail design. The middle of the stem rail is welled out so that only about half of the surface area of the stem rail makes contact with the bottom housing rails. 

These MMD switches are designed with the bottom of the stem rail beveled at a 45 degree angle, while traditionally the bottom of the stem rails are flat against the bottom, like Cherry switches for example.
