12 Pack 12 X 12 X 0.4 Inches Acoustic Absorption Panel, 3D Unique Soundproofing Insulation, Used in Home & Offices

Detailed review (Unpaid/Non Sponsored)I feel that this is a good product and deserves a 5-star rating. Here is why.Pros:-The product measures as advertised.-The product is shipped fast.-This product has a low odor.-This product adheres well with glue spray or other adhesive tapes.-This product is dense and is absorbent. It has multi-groove patterns that will also help absorb a wider range of frequencies vers a typical style pattern.Cons:No many to be honest, but if I have to pick a list of potential drawbacks here we go.-The product is vacuum shrunk to minimize shipping costs. This is a pro when you think of it because the buys save in price, but due to this shipping method you will not pull this out of the box lay it in your space. It will take you about 30-90 minutes depending on if you use a dryer, or if you air dry (would not recommend) but if you do at least 24 hours. Because the seller covers this and it's matched with common sense that these steps will need to be taken., I did not feel that this was worth a negative star but definitely worth noting for those who just read reviews.*If you air dry have the following:1 A clean lint-free space2 Space them so they are not touching3 do not stack them it will warp the foam4 Make sure your space is ventilated5 Make sure that you have an absorbent product under the foam. Towels, have them on Rack or something like that. This way all 6 sides can dry.

These arrive in a HIGHLY compressed state, nested face to face and vacuum packed. I would not expect these t oexpand on their own.After unsealing wrapping, I gently pulled each of the paired pieces apart and thoroughly soaked them with a hose outside. I wrung each piece out thoroughly, again gently, and soaked them again, leaving them in full sunlight for several hours to see if they would expand with the water contained within the foam to evaporate and possibly aid in decompression.This worked for about four or five of them, but the rest I had to tease into shape by lightly tugging areas that remained compressed.Ultimately, I was successful and got them all fully expanded as you can see in the two that I photographed for my review.These are not as dense as the pro level stuff, but I have seen a lot lighter. At this price point, I think they are an excellent buy and will serve well in chopping low frequency returns from the corners of a small studio.

These are great but DO NOT DRY THEM IN A DRYER. I’ve used these before and I think they’re great, but they are not durable enough. I soaked these things for a minute like it said and I put them in the dryer afterwards. Even after going through the dryer the foam was still wet and it was torn apart. Edges were ripped and it just makes it look worse. I would rather wait a few days for them to expand than have ripped edges and corners. If you’ve ordered a while ago and are buying more. Just so you know they are a bit smaller than before. Maybe an inch shorter on one side. So you should probably replace all the sound proofing instead of just getting more

I’m on the move to create the ultimate white gaming/work station office. I want most everything to be lighter colored which is really hard to do.These panels are close enough for me as I am being realistic in not everything can be shiny bright white anyways.I applied these to walls that had a little grit on them with this “EZLIFEGO” double sided tape I also found on Amazon as well. It holds up remarkably! Just make sure to press the tape on well and press hard on the panel for atleast a few seconds to ensure it’s going to stay on. I plan on getting some pearl white glue to use with my hot glue gun to seal the edges of them together for a more pristine look.I’ll probably end up purchasing atleast a few more packs of these or maybe even a dozen more to complete the entire office I work in. love the way they look and the quality of them seems like it’s really going to help block out noise which is also very important for me as I record music as well.

When I ordered these foam pieces, they arrived, smashed together, shoved into plastic bags, that were then vacuum-sealed, and then put in a box that should have never been able to fit all these items. By the time they got to me, they were warped beyond salvaging (even after waiting the recommended 24-48 hours for the air to let them expand).And oh god, the smell!!!! I can’t even describe what exactly they smell like, as I’ve never smelled anything like it, but it was so strong, that I had to contain the foam in one room, shut off from the rest of the apartment. Even then, the smell spread, and now gives me headaches.The only reason I didn’t toss these in the trash, immediately, is because the company was demanding the foam be returned, before giving me a refund.. How am I supposed to fit all those warped things, back into that box, without vacuum-sealing capabilities??This was hands down the worst Amazon experience I’ve had yet. terrible products, terrible customer service, etc. Do yourself a favor, and do NOT buy these. Total rip-off.
