Note Regarding Hori Low Profile Matte Buttons. Additional Compatibility Reports.
The Silencer pads compatible with the recent Hori Hayabusa low-profile matte version, but will require cutting off the side tabs. This is similar to Seimitsu PS-15 low profile pushbuttons. Additionally customers have reported compatibility with Samducksa 201 Futaba and 202 MX pushbuttons.
In November 2012, one of the highest voted ideas in our product suggestion forum was creating silent foam washers. This would provide an alternative to Sanwa's ground-breaking, but limited silent button lineup of OBSFS pushbuttons. Imagine having the ability to silence Sanwa OBSN screwbuttons, or the more recent translucent OBSC pushbuttons.
Now imagine the same for Seimitsu.
Available now is Silencer - a 1mm foam washer shaped to fit in both Sanwa and Seimitsu 30mm pushbuttons. Suggested by you, and tested over several months for performance and durability.
Unique Shape and material
Silencer is a 1mm foam washer that conforms to the internal housing of Sanwa and Seimitsu's 30mm pushbutton lineup. It also utilizes small "tabs" at each end of the washer, which additionally absorb the sharp sound created as the pushbutton plunger's tab meets the rim. Sanwa and Seimitsu - for copyright purposes - deliberately orient their plunger tabs differently from one another. Silencer's tabs can be oriented horizontally or vertically for Sanwa or Seimitsu's unique housing. For Sanwa OBSF, OBSN, OBSC and Seimitsu PS-15 pushbuttons, Silencer's tabs can be snipped off without affecting its ability to reduce noise.
Silencer's foam material was chosen for the closest match to Sanwa's original foam washers. For increased durability, an incredibly thin and flexible plastic film was placed on one side.
Installation
installing the Silencer foam pads into a Sanwa or Seimitsu pushbutton is straightforward. Place the washer - plastic film side down - into the button housing. Align the small tabs so that they stick out of the holes on each side of the housing. For Seimitsu PS-15 low profile pushbuttons, snip the tabs off with scissors and place into the housing.
Months of Play-testing, Sound and Endurance Tests
The objective of Silencer is to provide an alternative washer for Sanwa and Seimitsu pushbuttons that effectively reduces noise, but also matches the actuation ability and natural feel in Sanwa's OBSFS offering. To do this, we sent prototypes of the washer - originally in clear silicone and later foam - to a group of dedicated testers. Over several months, we learned that foam was more effective in matching Sanwa's original washer and absorbing shock while matching the actuation of Sanwa's own product. We also learned that "springiness" and "mushiness" was an undesired factor in other washers - first with our silicone prototypes, and later with competing solutions.
Further, we performed blind tests with individuals and groups, who assumed that Sanwa's OBSFS pushbuttons were installed. The washers were taken to tournaments in Philadelphia and utilized in joysticks swapped amongst players during the events. Those using Silencers indirectly reported no differences in feel to our testers; they didn't feel "springy" or"mushy", and were able to tap away normals, links and combos as they always did.
Finally, we performed tests in Seimitsu's PS-14 K and KN series of pushbuttons. The KN was most compatible due to its internal housing; Silencers proved effective for both in muffling sound while not restricting their unique feel. Though we couldn't perform blind tests, players that did use them were quite pleased that pads were designed for Seimitsu.

Exactly what you expect!
Great product. Easy to install, you don't even need to remove the buttons from the case if you can sqeeze on there with a flathead. Don't mistake the silencer name though. It definitely dampens the sound but it changes the press to more of a "thud" instead of a "clack". I personally felt my inputs we're much more accurate after I installed them. Something about the way it changes the press makes it feel more accurate to me although it could be placebo. 10/10 putting them.on all my sticks. Carter on May 23rd 2018

Easy to install, awesome product
These babies greatly reduce the clickety clack from your buttons. I'd recommend them to anyone. And you can't tell the difference gameplay wise, I haven't noticed any negative impact on my gameplay, and they're super inexpensive, so you have zero reason not to get these!

Great for your significant other
If your SI complains about your stick all the time and how noisy it is or anything like that. These are a GOD-SEND! The noise muffle is noticeable enough for you to at least say you tried. Kris on Feb 19th 2018

Good pads, even for none supported buttons.
Even though these washers are designed for Sanwa and Seimitsu buttons, having no other options I stuck them in my Crowns, and was pleasantly surprised. They dont totally silence the button but they do suppress them enough to not be audible when a game has audio, and near silent when pressed in a certain way. All this without making the buttons feel mushy. I cant really find any fault with them. Khan on Feb 6th 2018

Nearly silent
For a dollar these can't be passed up, just try them out Unknown on Feb 5th 2018

Perfect for Sanwa Buttons
The only difference after putting the silencers is the noise; my only concern was about if the buttons will keep responsive after the mod. I'm very happy with the result, easy to install, and very quiet! Unknown on Jan 30th 2018

Silent foam pads
Very impressed with them. Easy install and noise reduction. Makes the buttons feel and sound better. No more clacking on button combos. James on Jan 9th 2018

If you like silence these are absolutely needed!
I'm only giving these 4 stars because they take a while to get used to as they change the feel of the button, however they make your buttons almost 100% silent, it's actually pretty insane. How it works: Put them in your button and it stops the button from hitting the bottom of the button which is how it reduces the noise. If you like to play late at night and don't live alone, definitely pick these up. ^.Faith on Dec 16th 2017
