52 Pack Acoustic Foam Panel Wedge Studio Soundproofing Wall Tiles 12" X 12" X 1"

So, I bought a total of 9 packs for a 12x10 studio. I bought 5 packs of purple and black and 4 packs of all black. They transformed my recording studio, as i used them to cover from wall to wall and even my ceiling. The room is super soundproof and love it.When they arrive, they are vacuum sealed, meaning they are compressed. Based on the picture shown, add a little bit of water and throw them in the dryer and they will fluff up perfectly. I did not come with an adhesive but I purchased 3M 90 adhesive spray. Worked great.I recommend this product to anyone. 100% satisfied.

EDIT/UPDATE: After some time the water trick really helped. I recounted and it looks like only 8 of the 40 were less than stellar but still serviceable in the right locations. I can say with confidence that these are 100% worth the asking price! After a couple of days of of letting them hang there I replaced them and it came out 99% perfect!! I am sure some people have a few more or less that cam out bad but all things considered if you're willing to work with them they be suitable for most people. Order with confidence!My pictures say it all but basically 70% of them came out with lil to no problem. 33 were solid, 15 were less than satisfactory, I hung them anyway. I personally wanted some smaller ones as my office isn't that big and the thicker ones I have are too much to put behind me so I got these. I am not disappointed at all. For the most part the flaws you see in the pictures are more my fault than the product but some cuts are too warped to fit perfectly. I wanted them to fit perfect but it's harder to do than you may think 😂. The sound in my office is solid af now! If you're hesitant to buy just look at it this way for the good ones you get it's like a dollar a square ⬛ not too bad imo, with some extra to put off camera that are less than stellar looking. 🤷🏻

This was the second time I've ordered one of the lower priced acoustic foams after initially ordering a 24 pack with another brand (Dekiru) & seller. These were seemingly even lower quality than the previous ones and came feeling much more moist and smelled significantly more. They were also slightly discolored compared to the other pack but that was to be expected (sort of). Without comparing the two, the major downside was some were slightly off either in height or in width/length. For the price though, they weren't bad and now that I've had them up for 2-3 months (between both brands), they've actually felt like they've become more sturdy than when they were initially received.Granted, they regained their form with a few hours but leaving them to sit out inadvertently allowed them to get a teeny bit bigger. After the first week, they're going to feel extremely soft and fluffy which leaves the impression like they're not very good for sound dampening. However, again, after months of being up in a dry environment (inside an upstairs bedroom not a garage or something), they've become more stiff. So, in terms of feeling low quality, they're surprisingly feeling a lot more like mid-quality(?) I would say; basically they don't feel like a cheap knock off like when I first received them and let them expand for about a week or so.However, in terms of sound dampening, on their own, they don't seem like they have an NRC rating of 0.4 as they claim. But, I combined them with floor mats which together seems fairly effective. When I first received them, I tried seeing if I could hear an audible difference when placing a cell phone playing music under a stack of them and suffice to say, any change in volume was almost not even noticeable, throwing a pillow on top of my phone would've probably made a greater reduction in dB. Definitely get what you pay for but worth it if you're into a placebo effect and are using it in conjunction with some other sound dampening material.

The foam is thin, but impressively effective. We are using for our 13-year old son's bedroom who is a gamer. We have tall ceilings so we will need to buy more to cover all of the walls. 48 panels covered about 1.5 walls. Shipped quickly and description is true. The tape purchased was 3M, needs 3 to 4 pieces of double-back adhesive to stay on the wall.
