12 Pack Sound Proof Foam Panels, 12"X 12"X 0.4",Acoustic Panels Self-Adhesive,Soundproof Wall Panels High Density,Acoustic Panels Sound Absorbing for Wall Decoration and Acoustic Treatment-Black-12p

Best ever, i love them! They are so easy to stick on the well and work extremely well for absorbing the echo in my home studio. They look good too. I have purchased 2 packs and will get 1 more.

These are great for dampening sound on open walls and "boomy" rooms. They have a cool futuristic design and can be assembled in all sorts of hex patterns. I bought Black and mid grey and they look like modern art on the walls.Was getting a lot of bounce off the plaster wall behind my computer but these reduced the echo-ness considerably. They seem to hold to the wall pretty well. Easier than having to buy 3rd party tape and cutting strips.They do what they advertise. Would recommend.

I was looking for a subtle option to add to my apartment, as I hear everything that happens under the sun right outside my door.Pros: easy to install - just peel and stick, multiple colors options, aesthetically pleasing to the eyes, not thick, helps decrease low-pitch noises.Cons: doesn’t work well for high-pitch noises (like dogs barking, car horns), no instruction on how to remove, and I believe(?) they’re one-time use only.Regardless, I wound recommend these over the thicker, black foam squares.

The media could not be loaded.  These panels have worked really well and have stayed well-adhered even on a matte, slightly textured wallpaper. Got compliments on them every time I’ve posted them on social media or someone has visited the studio. Also a better price than others I’ve seen. Definitely recommend.

The room was still quite echoic after putting these up. Fortunately, all I wanted was something cute. The panels worked well for the time I needed them. However, trying to remove them was a nightmare. I used a hair dryer to loosen the adhesive. Unfortunately, it left adhesive and sometimes blue fibers on the wall as well. I tried multiple methods of slowly removing as well as soap/water, fantastik and olive oil. It was so stuck on the wall that it took hours using fantastik and scrubbing to get the residue off.Point is:they are super cutethey don’t dampen sound muchThey’re awful to remove

Applying these panels to your wall is like applying a sticker. Peel off the paper protecting the sticky back of the panel and smack it wherever you want on your wall. I only got 12 of them so I'm not quite sure how well 12 is supposed to work for an entire wall but people haven't been saying they hear me yelling or anything, so I'd say it's working well enough. In terms of hearing what's outside, I can definitely still hear noise, but I feel like most of it is entering from my door, which I decided against putting the panels on as my door has a lot of ridges to it. If you want something convenient that even a kid could install on the wall that absorbs some of your noise, then this is 100% for you.

I applied these to my wall and removed them after about 4 months. I tried removing the adhesive from the wall using various methods (rubbing alcohol, goo gone, heat, hot water and dish soap), nothing removed the adhesive entirely. I’m having to sand the entire wall and repaint. If you plan on using these, make sure you don’t attach to a wall if you don’t want to take a chance with having to repaint.They provided some noise cancellation, but were not worth the effort and money to fix the wall.

I ordered two packs of these acoustic panels for our office. Our office building is a bit older, and so it doesn't have very good soundproofing. However, it's not very secure to have conversations be loud between the different rooms. It was incredibly easy to set these up on the back of the doors and they have helped a LOT. In fact, a colleague came by and decided to order some for himself. They're classy, easy to install, and you can cut them to make room for wall features. All in all we were really happy with how it turned out, and we'll be ordering more.
