12 Pack Acoustic Panels, 12"X 12"X1" Sound Proof Foam Panels, High Density Soundproof Wall Panels for Home Studio, Acoustic Foam Wedges Absorbing Noise (Black)

These acoustic panels made a huge difference in my space! I installed them in my home office/studio, and they effectively reduce echo and outside noise. The material feels high-quality, and they look great on the wall—both functional and stylish.Installation was super easy; they stick well with adhesive strips or command hooks. I noticed an immediate improvement in sound clarity, making them perfect for recording, streaming, or just creating a quieter environment.If you need affordable and effective acoustic treatment, these are a great choice. Highly recommend!

Works ok. Some panels did not expand fully. Very sticky though! Easy to cut to size, use and apply! I applied them to thick paper so I can move them around and attach elsewhere if needed. Once they stick removal would be messy.

Work well. While remodeling our teenagers rooms, we put them in between the wall that tvs butt up to. If one turns theirs up, doesn't bother the other at all!

I knew these wouldn't be top tier in this price range but just some things to consider.They have peel off backings and an adhesive on the back, this adhesive barely held on my wall for a day. I think they know this so they also include double-sided adhesive squares. Be warned these are much stronger adhesive and will peel the paint off your wall, unfortunately they don't seem to stick very well to the foam and even after redoing the entire wall using these squares I had several fall off over night.The QA on these are also not the best, not every square is cut to the same dimensions, so this makes laying out a nice alternating pattern on your wall more difficult. Nothing was way out of whack but I'd say they were +/- .25 of an inch.They come in a vacuum sealed pack to compress them for shipping. All of them came back to life nicely aside from the top and bottom 1/2 pieces per package. Those had some issues returning to normal state, even after following the instructions for how to restore them. Tugging on them with your fingers was the best way to get them back to shape but they still don't look as nice as the squares that weren't on the top or bottom of the pack.Several days in and they still stink, it's not the most offensive smell but it's unpleasant.Compared to something like the Auralex foam squares, these can't compete, but overall I'm pretty happy with the way my wall turned out for the price.Verdict: they are OK, decent for the price but not without fault.

The adhesive is very weak. Even with prepping the wall, cleaning and letting it dry, they’ll fall off. The cuts on them are very inconsistent, so alternating then vertical to horizontal makes it easier on the eyes. If you want them to stick well, buy spray adhesive and apply them on the back. If you can’t be bothered doing extra steps, just avoid this one all together.You’ll also need a steamer to let them puff out more since some corners and edges will be flat even outside the vacuum sealed bag.

As described

Great

We purchased these to add some sound dampening to a commercial refrigerator. They have been installed for 10 months and have turned yellow from the original gray. So the foam is degrading and will probably start crumbling soon. The adhesive is drying out and failing. They worked well for some sound absorption, but are not a longevity product.
