12 Pack Self-Adhesive Acoustic Panels, 12"X 12"X1" Sound Proof Foam Panels, High Density Soundproofing Wall Panels for Home Studio, Acoustic Foam Wedges Absorbing Noise (Gray)

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.

I got this for my dog house. It only stuck for about 5 min then fell off. Kept trying to get it to stick and just will not stay up. Do not buy this, its a waist of time and money.

I purchased this set of gray acoustic foam panels, primarily for their aesthetic appeal, with the added benefit of potential acoustic enhancement. However, my experience with these panels has been less than satisfactory.The panels arrived in a pleasing gray color that perfectly matched my interior decor. They were easy to install and initially added a professional touch to my space. However, after just a month of use, I noticed a significant color change. The once appealing gray had transformed into an unattractive army green. This unexpected color shift was a major disappointment, as it clashed with my room's color scheme and overall aesthetic.As for their acoustic properties, I can't definitively say whether they made a significant difference. My primary motivation for purchasing these panels was their aesthetic appeal, so the potential acoustic benefits were a secondary consideration. However, even if they did enhance the room's acoustics, the unsightly color change overshadows any potential benefits.In conclusion, while these acoustic foam panels may or may not improve room acoustics, their aesthetic value significantly diminishes over time. I now find myself in the position of having to remove them due to their unappealing appearance. I would not recommend these panels to anyone purchasing them for aesthetic purposes. The product did not live up to my expectations, and the color change was a significant drawback.

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.

I bought these for the claim that they inflate immediately upon opening, but they DO NOT. You still have to wait 24-48 hours. And I waited a full 48 hours, and 8 of them STILL haven’t risen like they were supposed to. The best things I can say is that they arrived a day earlier than expected and the adhesion is really good.
