I bought this mostly for the decoration if I'm honest. It was cheap enough that I figured there would be no audible benefits, but it did remove a slight echo in the area of the room I used it and I'm pleasantly surprised about that. I had to soak them all in hot water, ring them out and let them dry thoroughly with a dehumidifier before installing.

So far so good! I followed the instructions and they all came out perfectly. I filled the tub about 1/3 of HOT water, let them soak there for a little bit. When I got the water out, I made sure not to squeeze them too hard and I rolled them following their natural lines to avoid any weird wrinkles. the I put them in the dryer for 30 minutes, mind you, some of them might still be a little moist after a day or so. I just noticed that today but I threw them back in the dryer and I hope that does the trick. Now off to install them!

The material is very good, it enhanced my bedroom studio. Love them.

Awesome product works better than i thought it might. I built a shop vac cabinet for my CNC routers, to try to quiet down the sound of the shop vac; nothing is more annoying than the sound of a vacuum cleaner running the whole time your routers are running lol. Figuring the sound would really echo inside of the cabinet and turn it into a speaker so i bought these in anticipation of that. Sure enough once i had it done i was getting >85 dB, but once I lined the inside of the cabinet with the panels the sound dropped to >60 which is hardly noticeable over the rest of the tools. I do wish the adhesive was a bit stronger, but once you have pressed it firmly into place (maybe roll it out) i think it will be fine. I'll be buying more for sure

UPDATE: As promised here's an update after unpacking over 200 panels. They are still the cheapest 2" panels and may be very worth it in small volumes or if you don't depend on the true measurements of the panels and have time to request replacements. While my first few packs were fine, the additional 16 packs I bought had mixed results. I added photos to show the permanent heat deformation from the manufacturing process that won't go away no matter how many hot baths you soak them in. The foam is already melted to it's final shape as shown. Additionally, the dimensions of the panels range between 11.75" and 12" squared which is also depicted in my photos. The somewhat good news is the deformed panels were only about 10%; however, the smaller 11.75" dimensions were far more common. I have a "sunk cost" dilemma at this point and found a way to make what I have work. I would have asked for replacements, but would have been a shipping/time hassle and I was eager to finish my isolation booth. If others don't have to depend on exact dimensions or have time to push back to ask for replacements, this is still a MUCH cheaper option for 2" panels and the foam quality of the good panels are great. If F.Stop added a disclaimer these are known issues and adds that as part of their return policy, I would happily rate this 4 stars, and if they fixed their QA issues to ensure true 12"x12" and no deformities F.Stop would be 5 stars and the best option for the price on Amazon.ORIGINAL REVIEW:I spent a lot of time looking for these as I need over 200 for an drum set isolation booth, and these are easily the best price for 2" thick panels. I noticed many complained about how malformed the panels were, so I only bought one set to test. As you will see in the pictures, I had no issues whatsoever. The package came with 2 methods to restore the shape, and the second method (see photos) worked in seconds. This is the same solution for many other brands of foam panels like these. I used very hot water, and you can see the comparison photo showing what they looked like before and after being soaked and dried. I also noticed many complaining the panels were not truly 2", but as you can see in my photo these panels definitely are 2". I don't know if F.Stop has changed their product and instructions or if buyers were simply not trying hard enough to restore the shape of the panels, but I have had no issues whatsoever and have purchased the remaining 16 packages I need. I will provide an update once the rest have been received. For now, you cannot go wrong with the price and quality of these entry level panels.

I essentially bought several different types/brands of acoustic foam panels because I was worried about different in quality and delivery. I bought1. "3 of New Level 6 Pack- Acoustic Panels Studio Foam Egg Crate 2" X 12" X 12"2. "12 Pack Set Acoustic Foam Panels, Studio Wedge Tiles, 2" X 12" X 12" Acoustic Foam Sound Absorption Pyramid Studio Treatment Wall Panels"3. "12 Pack Set Acoustic Panels, 2" X 12" X 12" Acoustic Foam Panels, Studio Wedge Tiles, Sound Panels wedges Soundproof Sound Insulation Absorbing"The first is from "Urban Mall", and the other two are from "F.Stop Labs". This review is comparing item #2 with item #1.First, both #2 and #3 arrived together, in a single box, compressed into individual 12-pack bags as can be seen in the first picture that compares the foam panel with a bag next to it. That panel in the first picture is a panel that was taken out of the bag, aired for Sunday, Monday, and Tuesday (72 hours). After 3 days the foam was all compressed, and looked really bad. It did not uncompress at all. That was the first method the seller recommended to use. Then I soaked the panel in water, squeezed the water out, and let it air dry over night. The next morning it was still damp, but the overall shape was better.The second picture compares a panel that was uncompressed for 3 days (on the right) with a panel that was left wet and then air dried (on the right).I would not recommend you to get #2 or #3 because you will have to wet each panel, squeeze it, and then find space to let it dry - that will take quite a large space. So that is one reason why not to get it.Second reason why not to get these panels is because of the quality. As you can see in the last picture, the panels arrive wrinkled, and have additional damage cuts on the back side.Third reason why not to get these is because of the product specification is not matching what you will get. I ordered the 2 inch thickness foam panels. Letting the panel air decompress will bring it to about 1.5" at best. Wetting the panels and then drying them will generate a better shape, but will still give you panels with thickness of 0.75" at the lower end, and 1.75" at the higher side. Not even close to the 2.0" that was ordered.
