HONKID Keyboard Foam, Sound Dampening Foam for Mechanical Keyboard Bottom, Made of LE-20 Poron, Black (H 3mm)

It's really hard to put into words how this works. If you are looking for a deeper thock sound and premium feel for your switches, this is the kit for you. I also paired this with a Poron gasket and pads (the little squares with cutouts that the switches rest on). With all three kits installed it takes your keyboard to enthusiast level. The foam needs to be cut to the desired size to put on the bottom of your board. That was easy enough just measure and match. Depending on your board you might have to make little custom changes, but it is worth it if your into modifying. For mine I had to make a little u shape cutout for where the USB-C port was as this raised it to much and wouldn't align with the port.

I got this for my first ever experience assembling a keyboard, so my opinions are naive. But, I think this works well! I was assembling a 75% Artemis Paragon keyboard, which doesn't sell components like foams, so I needed something I could customize. I did a shoddy job cutting the foam, but it was just the right thickness for everything to be nice and snug (and the sound is quieter too).

Nice, dense foam. It does what it is supposed to and took the ping out of my aluminum case. I paired it with the tape mod and it worked perfectly.

Surprisingly effective, for such a thin material. I actually chuckled at the difference in noise with vs. without this thing. One drawback is that depth is insufficient (for me anyway, and I’d say probably for most). I had to cut it into two pieces to cover the areas where the keyboard makes contact with the desk surface. Despite this, I’m still giving 5 stars because the performance exceeds my expectations, but a lot.

Made my old GMMK board sound so much better. Before this mod it sounded very hollow, now it sounds deep and doesn’t feel empty anymore. Effective, but a hassle to install.

I added this foam to my Epomaker TK68 with 3 layers masking tape and this is how it sounds! It gives it a very deep, and slightly poppy sound. The switches used in this video are lubed Gateron milky yellows. The foam is nice because it’s not too thick and fits into most keyboard cases. It even fits great in this stacked acrylic keyboard—which I wasn’t expecting because stacked acrylic keebs don’t have any actual “space” inside the case.

The pad was surprisingly effective but taking my keyboard apart for the installation was a little nerve-wracking since I've never done it before. $14.99 (at the time of this review) for what is probably fourteen cents worth of foam seems a little excessive, but it does what it says it'll do if you take your time and follow the installation guide.

I used a combination of this and neoprene for my keyboard and they sound great together!

Great. Thanks

It's nice you cut it however you wish. Works.
