Grid Style Acoustic Foam Panels - 12 Pack (Black)

Use a hair dryer on high heat on the design side and then focus on the uneven edges or sides. You can put then in the dryer for 30-40 minutes and then finish with a hair dryer. Thank me later. If you want try warm water on 1 or 2 first.

These panels are more effective than the pyramid-style that I've tried in the past, which leads me to believe that this style of noise cancelling panels is a better deal in terms of noise proofing. They're thicker and larger overall, so it's nota direct comparison, but I would urge anyone that's not entirely concerned with aesthetics to opt for this deeper panel since it does work better (in my experience).The panels come vacuum sealed, and only a few of them required "activation" by soaking them and them drying them out again. I'm glad so few required that, because it's definitely a pain. That being said, you can put them in the washing machine on a gentle cycle, per the instructions, which is more convenient than using a bathtub or similar.Overall, I think these are a good deal and would do a good job reducing the reverb and overall noise levels in may spaces, such as a home office. I would gladly recommend these noise cancelling panels!

These foam panels have a different design than my other ones, and that design yields more foam overall than the others. The entire edge is a full 2 inches thick, and the indentations are also fairly shallow. Unlike some others, they also fully expanded on the first try getting them wet and then wringing them out. The full price is more expensive than other sets. but as of right now there is a 15% off coupon that will bring their price right in line with most of the offerings I have seen. Unless the style is a problem for you, I suggest giving these a try. They will offer a bit more sound absorption than most of the other 2 inch thick models I have seen.

I have been very impressed by the design, build, and effectiveness of these 12.6 in sound suppression and echo reduction acoustic panels.Unique sound dispersion grid that is very effective at eliminating wall echo while also reducing low-frequency booming.These panels expanded on their own within a few hours and without having to soak or use any other method for expansion. They are a full 2" thick with oversized dimensions of 12.6 in. They are also aesthetic when mounted on wall or ceiling.The panels do not have any adhesive backing and can be applied to a wall with either spray adhesive or other methods. I use corner strips of Bell & Howell two-sided "Alien Tape" which is highly effective and allows the panels to be removed in necessary without damaging wall paint or leaving residue. (Alien Tape is available on Amazon)I couln't be more pleased with this set of great acoustic panels for use in my Basement Recording Studio, where I livestream, as well as produce VoiceOvers and videos. They rate a very high FIVE STARS with me, and earn my honest and very hearty recommendation. Much better than typical wedge panels!*If you found my review helpful to you, PLEASE let Amazon know by clicking the "HELPFUL" button below!

First off, I bought different acoustic panels before these ones and they were a nightmare. So naturally, I was expecting this to be a whole project and was prepared to dedicate a lot of time to it. However, once I received these I decided to just lay them flat on the floor and left them overnight. Come morning, they were all perfectly expanded and I couldn't believe it. I really didn't think it was going to work but it did, so it's worth a try to just leave them out if you're short on time/patience. I was so surprised by how thick these came out to be too because the other ones I own are not thick at all. The quality on these is insane and they really work! (At least in a closet which is where I have my studio.) Not sure about bigger rooms but I'm willing to bet if you have enough of them, they will do just fine. I absolutely love these and I'm so glad they expanded on their own and I didn't have to do any washing, drying, etc. Definitely check instructions though because I just kind of ignored them and maybe I got lucky, who knows. Overall, these are amazing.
