52 Pack Acoustic Foam Panels 1" x 12" x 12"Acoustic Wedge Studio Foam Sound Absorption Wall Panels (Black/Blue)

I ordered these more to cover the walls, and add some echo cancellation, as I live in a historical building that is just starting to do renovations, so my walls has cracks, they are uneven and the paint isn't the best looking, but not tons I can do about it as I rent. Since i have a Youtube studio set up in my room, I figured the best way to make it look more modern was acoustic panels. They do also help with echo cancellation, that "stadium" type of sound, but they don't block noise out from other areas, they aren't for soundproofing, they are designed to stop sound from bouncing around, which does quiet things, such as a window fan, that has it's sound bounced back from the opposite wall. They come VERY compressed. maybe 12 inches thick, and I was worried as it said it could take 48 hours to expand, unless you soak them in water, then it can be reduced to 1-5 hours. However, as soon as I opened the package, POOF they expanded nicely and were pretty much good to go, a few panels were still squished, but they are good enough to go on the wall. The pictures I have attached are from under 60 seconds after opening the package up... One thing, is that they do stink... they smell like really strong mildew, and my skin felt a bit itchy where I had touched them, then myself, but it went away fast. The smell is not mildew, just the smell from the polymer. This is the same foam you get in like a cheap mic windscreen cover, or cheap earbud covers. very fluffy and not rigid. I put mine by a window with the fan pulling air out, and it went away within an hour, anyone that has ordered a mattress recently will be familiar with the process. The panels are large also, very large.

I love these ones are more easy than the purple ones I bought previously

Looks great and easy to install. the adhesive strips are easy to use too and stick well too. Good for studio sound insulation

Quality is better than expected, wouldn’t hesitate to order again

These were a little disappointing because they are not sound proof. Not even close. They do help buffer the sound a little, but I wish we chose something different. My son does appreciate the cool design his walls have though. They were really easy to apply to the walls and have stayed up perfectly over the past year, for whatever that is worth.

They make a very noticeable difference with just the 52.

I've ordered these twice. The fist order has 2 defective purple panels, one of which I just used on an edge that didn't matter. But on the second order, a bunch of the purple panels were cut wrong... they are impossible to use. I already installed the others before I found these... not sure what to do - tear them down and return?? Contacting the vendor gets me into an automated loop. Ugh. Sad because other than about 9 unusable purple tiles, these look great installed. :o(

Awesome they aren’t tipple A quality but get the job done and for a good price super easy set up too. Thickness is average for price but absorbed the sounds just fine even for being relatively small.

Look great

Colour discrepancy

The ones that expanded when I opened them were great. The red ones expanded fine no problem, the black ones 90% of them did not expand even after 24 hours. I read the instructions it said to wait for 8 hours or use water to expand them however after 24 hours they still have not expanded. Really disappointed I have asked Amazon to send a new pack of the black ones hopefully they will
