24 Pack Acoustic Panels,2" x 12" x 12"Sound Proof Foam Panels for Wall,Fireproof Absorbing Noise Cancelling Panels,to Absorb Noise and Eliminate Echoes. (12 Purple+12 Black)

I thought the quality was fine, especially for the price... they do need a day or two to fully "decompress" - but after went on perfectly. I used four sound foam Gell stickers on each, and not one has fallen since I put them up, and they sit regularly in 110° F AZ garage. Remember, these are NOT sound absorbing / noise reducing foams... they are simply to control the reverberations and reflections. :-)

I used these to create an absorption section on a wall. These are not professional panels, but I was doing it more for decorative reasons than true acoustic treatment. ...That said, they did have some positive effect. These will only help with high frequency reflections, they will not prevent low end problems or noise problems.I followed the instructions, which advised rinsing in water, ringing out by hand and then drying in the dryer. When unwrapped there were several panels that seemed too smashed to use - but after washing they almost all recovered. The problem was that almost all of the magenta squares ended up with little pits in the surface which are quite noticeable up close. The black squares were much better but still had a few pits on a couple -but also less noticeable, since black.BTW... I highly recommend 3M #77 Spray Adhesive with the note that they will adhere right away so you wont be able to move them after contact. The CRC product I also tried would allow movement but didn't hold quite as well around the edges.

I had zero problems getting this foam expanded back to normal size. Made a huge difference in the room acoustics. I feel like I'm hearing music for the first time!

I might have gone overboard setting up the home studio here, but they were what I thought was a good value. I like how they're vacuum packed and expand to perfect shape after releasing them from their packaging.Put them up with little sewing straight pins from the wife's sewing box. Shhh don't tell her.Easy peasy.Nothing over complicated.I'm satisfied.They feel great, look great and do the job.

I just got this today and opened it and I did not had to wait 24,48 hours like they said same day install and it works great with a little bit hot glue in the corners not to much hot glue.Makes my daughter room looks good with the colors and I guess it can tell a little bit the sound difference I will get more for the other room. I wish they can offer me more discount..

It would be 5 stare but there is one Purple panel missing but other then that, it's good

I ordered a total of 3 sets for my teenage son’s room. He absolutely loves them! They have definitely made his room more dense! It’s helped a lot with him streaming with his friends online while they play games and chat (or yell 😆). They’re worth it for the price in my opinion.They come in vacuum sealed plastic and do expand rather quickly. Only one set I had to wet three of the foam squares to get them to expand.I have attached a picture of them in their packaging, versus after opening.As far as getting them up, my son used double sided tape (a piece on every corner). It’s only been a couple weeks since he placed the first one, and no issues with any falling yet.I’ll try to include a picture of his walls soon for this review soon (ish).

These are a great price point and they do help in corners at reducing standing bass waves, but in the description it says "soundproof"; they are NOT. So many of these throw around that phrase and making something "soundproof" is not only close to impossible, it would never be at this kind of price.Rant over.
