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)

These acoustic sound absorbing panels look just as good in person as they did online! I was afraid to get them and find they were thin, light and foamy. But these are nice and dense and the pyramids give it an extremely cool, professional look!I did have a couple issues that I contacted customer support about. First, I was impressed that they clearly display their email address on a flyer in the package to insure the customer can count on support if they need it. Within just a few hours of emailing them, they got back to me with a solution and happily made it right! Next time I need more, I won't even bother shopping around, I'm so pleased with this product and customer support!The tiles stick great to the wall, but can also be removed without any damage to the foam or the wall. Even though these are peel and stick, they also come with adhesive squares if you need them. So far I have not needed them. Some of these panels fit near perfect into my desk wall shelving, so I just pushed them back in each one and they are snug enough where I didn't need to peel and stick them. But I also have some installed on the wall, and those are holding very well.This room was a bedroom with a twin bed, plus a home office. But I decided to make it just an office space with another desk and computer, so I moved out the bed. I couldn't believe the sound difference. Without the bed, everything was echoing, loud and just made the office have a "cold" like environment. Even just typing bothered me because it just sounded too loud. I didn't even like talking in here. It's amazing how just by hanging some panels on the wall changes the whole environment into a room you enjoy being in.If you've never tried sound panels, the price is worth it, especially considering how much it can improve the comfort level of a room. They are not just for professionals or sound studios. They would also be great for a kids bedroom, and you might find you won't have to turn up the living room TV so loud anymore ;)

Works as expected.

Soundproofing ok, but the self-adhesive isn't very good. Mine starting falling off in about a week. I tried using double face tape to fix them, but the tape didn't stick to the tile for more than an hour or two. I finally stajpled them to the door.

Good product. The paper for the adhesive backing can be tough to peel off, but the adhesive itself is awesome. These panels aren't moving, period.Only complaint is that the squares aren't totally symmetrical. You'll be lining up the next panel, only to realize the squares don't align perfectly. Does this effect performance? No. But it'll bug those with ocd

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!

Very easy to install works very good

The whole reason I bought this was to have an already applied adhesive on the back. The fact I now need to use another adhesive or double sided tape is ridiculous more than half the tiles fell!!

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!
