Sonicism 12 Pack Pyramid Sound Proof Foam Panels with Self-Adhesive, 12" X 12" X 1" Acoustic Foam Panels of High Density, Soundproof Wall Panels Fast Expand, Sound Absorption and Decoration (Black)

The media could not be loaded. Overall we were happy with the product as we bought enough to help soundproof a 10x12 room that we built for shooting video content for digital media. Out of all of the panels we purchased, we had 3 or so that after time didn't adhere, but it could have been due to the humidity in the room since it's been a 100+ weather here in Texas for the past 3-4 weeks now. They provide a good adhesive tape with the product in case you have a panel or so that doesn't stick. Other than that, it is a really great quality product, and one we would recommend to those who are looking for noise cancelling/absorption for a space they are trying to soundproof.

Works perfect and stuck on wall perfect was easy to install and is built great and they look really nice of comfy on my wall and the thickness of them is good they stick to the wall really easy my fingers kept getting stuck! Would recommend, and the build durability is also great they are lasting!

I bought 36 of these to deaden my small home studio - not enough to fully cover the walls but at least they cut down on all the echo. The adhesive is very effective - I followed the instructions and gave each one a thorough push against the wall and not one has come loose.Problem is, I didn't do enough research and was not aware of sound absorbing blankets. I just got six and hung them around my space and they are great, especially combined with the foam pads that are still up.If you decide to go the foam pad route, I cannot recommend highly enough that you first lay out a barrier of blue painter's tape on the surface you plan to stick the pad to, and then stick the pad to the blue painter tape. It'll take you about 5 minutes time per pad, if that, to cut off the tape and stick it to the surface, but you will save yourself so much time, mess and effort in the event you decide you want to move or remove the pads.I now know from experience what an utter pain it is to remove these and then remove the chunks of foam and adhesive that remains (mineral spirits or denatured alcohol work well, but what a mess!).So in summary, the pads absorb sound pretty well and the adhesive is great - perhaps too great in the event you find you want to move the pads.For my part, tho, sound absorbing blankets would have been the better choice.

Product works as intended, but cosmetically a third of the squares had permanent damage due to packing issues. Ass been in pics above, some squares were smashed and deformed. After giving them days to expand and form, nothing changed. 1/3 of the first package I received were like this.Adhesive is strong. Dampens sound very well.It's a hit or miss on the quality tho.

Out of the 2 packs of 6, 5 were squashed on one side and I had to cut off 2 lines of smooshed, not inflatable product. They come with extra stickers if you need them- pay attention the backs of these tiles have removable paper so they have a full side to stick them to the walls and the addition tape is for mess ups!So far 3 weeks after install they are stuck very strongly to the painted drywall. None have peeled and there are 48 tiles. I did cut up a few so technically there’s about 50. Aside from the damaged edges on some (I needed to cut a line anyway to fit the last row in) these are a good product.Update:1 year later and they are still on the wall. Doing fine.

I bought these explicitly because they show 3M adhesive backings in their ad. The adhesive on this product is NOT a 3M adhesive. It is barely sticky, it won't even grab paper. These are also listed as 2 inches deep. They barely crest 1.5 inches. Total garbage. Fortunately with Prime I don't have to deal with trying to repack this. See photos.

Very easy to install works very good

I saw a lot of reviews saying that theirs came damaged. Mine came flat as well, they’re not damaged all you need to do is run your nail, coin, ruler, something hard over them and they pop right back up. Shame people leave bad reviews without trying to fix them :/ as far as quality they do a decent/good job. you’ll need a lot more if you want a huge difference in sound reduction. I used these to keep the sound in because my buildings walls are thin and they definitely work. worried about removal though because they super stuck to the wall. UPDATE: These were super hard to get off the wall. It was very time consuming and was left with grease stains. If you don’t use an adhesive remover they will rip off the paint so be careful!
