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-Grey)

You need to separate the rows from each other, when mine were delivered, they weren’t taking shape until I realized the end was stuck to the adhesive, making it impossible to reform to the original shape.

I would give this a 5star rating but I dislike the two sided little sticky tape. Works good I should had bought two more but it has muffled my sons room a tad. I feel two more might do some justice. The tape is small and time consuming. Still gets the job done just small. Great look to my sons room and the price is right. Again, no issue just the tape I don't feel for. Durability is just fine and I've heard of a smell, we haven't detected that.

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.

Does not drown out any noise , what so ever . Don’t waste your money !

Bought these for my son’s gaming desk. Will be buying more soon. These are think and great quality

Very easy to put where you want to put them. Peel the backing paper, after a good clean of the surface, and them stick where you want it to be.

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.
