50 Packs Acoustic Foam Panels Pyramid 2"" X 12"" X 12"" High Density 25kg/m3, Soundproofing Foam Noise Cancelling Foam with 300 PCS Double-Side Adhesive, FS0307Y

Alright so I'm aware that some of the biggest issue with this product is 1) the double sided adhesion stickers and 2) squished/flattened fpam panels.I found the best way to address peeling the covered side of the sticky pads is to actually rip it. The pads themselves have some stretch to them, so you can actually gently rip the covered covered portion to allow you get a better grip on it. Once you try it, you'll understand. (Don't try and peel it, try gently ripping the yellow paper and it'll be way easier to manage)As for the squished panels that don't seem to inflate, another reviewer mentioned that if you run it under some water (warm or otherwise) it'll inflate just like the others. I had a really flat one that might as well have been 1" or .5 inches but after running it under some water, it inflated like a sponge.You can squeeze the excess water and just set it outside in the sun to dry off. (or use paperwork towels, whatever you have).Great product and came as intended. May update my review in terms of sound absorption. ('m aware this isn't a noise cancelling product, those cost way more).

These panels do the job nicely and economically. Easy to cut and custom fit. Dampened and absorbed the sound as expected...The adhesive tape dots are included with the purchase also worked very well.

The place where I live cannot block noise. However, I missed the return window, and now these soundproof foam panels are piled up at home, completely useless.

This product did not have enough double sided round stickers for all of the acoustic squares provided

I have ordered two packs of these. They arrive vacuum packed and flat. The first pack took a couple days to expand out to the 2 inch depth. Some of the pieces didn't expand the whole way. The second package popped out to the 2 in depth within minutes! So fun to watch. :) Easy to install. I'm still hanging them in my booth, so I don't know about sound mitigation yet.

The media could not be loaded. I made sure to follow the instructions and if you do so this product does work correctly. There is no weird smells, they all expanded evenly. Shipping quality was also great!

I was looking for a solution for my office at work, I have a large office 20x30, and in that room, there is a closet that houses the Breakers and such for the entire building, one of the pieces of equipment in there was quite loud, giving off a constant loud electrical buzzing, Sounded almost as loud as a phone vibrating on a desk 20 ft away or so, but constant. I found these on Amazon. I thought, for the money, they were worth the shot. I installed them this afternoon and shut the closet door; this took the sound from a noticeable audible level to a very faint hum, no louder than the mini fridge in my office; in fact, I never noticed the fridge sound before, and now I do. Very impressed.

Keeps my network cabinet nice and quiet.

The foam acoustic panels worked perfectly, once I put the stickers on the foam panels I had a really hard time peeling of the paper part of the sticker maybe because of my big hands but other than that they worked perfectly.
