Upgrade 12 pack Sound Proof Foam Panels With Self-Adhesive, 1" X 12" X 12" Acoustic Panels Quick-Recovery, Acoustic Foam Wedges High Density (12pcs, Black)

They are easy to install with the adhesive sticker. Just make sure to press on it when installing it. Either way, it sticks very well. They’re light and they work the way they’re suppose to. It eliminates sound. Perfect for our little studio. Just keep in mind they take a while to fully form because they come compressed in the package!

These are probably the best out there for the price and convenience. No soaking or hair dryer/dryer needed. I open the package and laid them out on the bed for about an hour. The peel and stick adhesive is strong, just prep the wall with a clorox wipe. I purchased these for my son's room because his soundbar sub was shaking the wall. It did a great job at minimizing the bass felt in the living room.

Upon receiving these curious foam panels, I must confess my initial reaction was one of bewilderment. Such peculiarly shaped objects, reminiscent of a bedraggled sponge that had undergone an encounter with a tailor's scissors. However, one should not be hasty in judgment, for appearances can deceive. The installation process, dear reader, was an experience not unlike engaging in a spirited tussle with a particularly tenacious octopus. Yet, with patience and perseverance, the panels eventually yielded to my determined hands and adorned my chamber walls. Now, let us discuss their purpose, shall we? These foamy fellows purportedly possess the supernatural ability to quell the unruly cacophony that permeates one's living quarters. In truth, I half-expected them to serenade me with a chorus of "Hush, hush, dear sir!" in dulcet tones. Alas, my dreams were but ephemeral whimsy. To assess their efficacy, I decided to embark on an auditory experiment. With a rambunctious gramophone blaring forth the swinging tunes of yesteryear, I positioned myself within the confines of my newly fortified sanctuary. Lo and behold, the decibels were indeed stifled to a somewhat more manageable level. The wall-mounted sponges, or rather, the sound dampening panels, had achieved their designated purpose with modest success. Yet, dear interlocutor, it is vital to temper one's expectations. These foam panels are not miracle workers. They cannot transform a symphony into a somnolent whisper or reduce the exuberant laughter of children to a mere mouse's murmur. No, no, they are but humble servants in the realm of acoustics. As I reclined in my newly subdued chamber, I pondered their aesthetic impact. Ah, yes, their appearance. The foam panels, while practical in their function, possess a somewhat utilitarian charm. One cannot help but feel they belong in the modest abode of a music enthusiast, rather than adorning the opulent halls of a grand mansion. In conclusion, dear reader, I find myself in a position of moderate admiration for these acoustic sound dampening foam panels. They may not revolutionize the world of acoustics or transport you to a realm of perfect silence, but they certainly make a commendable effort in taming the auditory chaos that often plagues our lives. If you seek a touch of tranquility without sacrificing your entire fortune, these humble foam panels might just be the ticket. Good day to you, sir or madam, and may the melodies of life grace your ears with harmony and mirth!

Great acoustic panels, helped reduce the noise and echo in a small room that I have a piano in. A few of the panels had squished/shaved corners that didn't fill out, but its not too bad. I found the best way to install them was to buy a presentation/poster board from Walmart, like the kids use for science fair projects, and install the panels on the board. The adhesive on the panels worked out perfectly. Then you can thumbtack/nail/screw the poster board to the wall. Easier to take down or reposition that way. Good luck.

These are great for that pro studio look and feel! These really do fully expand within a few mins like it says. Yes the adhesive backing does work beautifully with one catch, you have to read the one key instruction that says “clean the surface you’re sticking them on first.” I used Lysol Disinfectant Spray, let it dry for a few mins and I haven’t had any problems after a couple weeks of them being stuck to the wall. Before sticking them though, I used thumb tacks to place them on the wall in the design I wanted to make sure they would work in the area I wanted. The only con that you personally may have and it is not a con for me is: These do not do much in terms of sound dampening. They do a little and I can hear a mild difference but nothing that’s going to be useable for a live band or loud environment. For me, I knew these weren’t going to be that and I was okay with it for that’s not what I bought these for. I needed these for video content and over all atmosphere feel and these are excellent for that!
