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.

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.

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.

Honestly for the price I feel like you should get more than one keyboards worth. Not like 20sq ft or anything but dang. It does help get some deeper thocks though! Easy to cut to fit, sounds great, and stable.

Excellent foam. Works great. The only complaint I could possibly have is that they don't pre-cut it into perfect sizes for keyboards. You'd think they'd do that to save on wasted foam and just provide one size fits all for the various form factors but no biggie, just cut it to size and you're good to go.

There is probably a bunch of stuff you could put in your keyboard to dampen sound lying around your house, but you were curious, and the internet led you here, to poron foam. It's true, this stuff is good. I had a fun little project upgrade a budget Redragon board with Outemu reds (the most pingy, hollow board I've ever heard), and this poron foam combined with aditional sound dampening foam between the PCB and the plate and a tape mod turned this awful-sounding board into an absolute DELIGHT to type on. Again, poron foam is just part of the equation, but this stuff worked, and I've got a bit left over since the board was TKL and there's enough foam for a full size board. Would buy again!

Do you have a mechanical keyboard that sounds a bit tinny, or maybe a little hollow? Is it cheap and mostly made of plastic? Buy this. It'll feel like your keyboard just added 2-3x the value.

Just a roll of Poron to cut for your keyboard. I used one later for the bottom of my GMMK Pro. Its nothing special, but it does exactly what you want it to for case ping and sound dampening. Appears to be legit Poron and not some fake foam. Can be a pain to cut, so make sure you have a good cutting utility.

Great. Thanks

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