Upgrade 36 pack Sound Proof Foam Panels With Self-Adhesive, 1" X 12" X 12" Quick-Recovery Acoustic Panels, Acoustic Foam Wedges High Density (36pcs, Black）

Got them today, did my measuring and placement testing. Opened them up and let them sit about 30min and they formed nicely. Super easy to place on the wall, and they stayed nicely. Noticed a difference right away, not so tinny and echo-ey sounding now, more full sound from my Towers and Center. I'm running Klipsch speakers in a 7.2.2 configuration. Have about 15 sheets left so I have some more to use. Biggest difference was setting them up behind the center channel and TV area wall.

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!

Not all of the pieces fully expanded. This occurred mainly on the edges. Overall this product is pretty good, I just expect it to fully expand to get a full good review. The initial adhesive is good, but I cannot speak to the longevity of it.

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.

Exactly as advertised. Good price. Extra double sided tape helpful. Placed inside intage grill wall to reduce room noise from transferring to basement through hvac intake grill. Reduced echo and noise significantly. Glad they are 1” to allow good air flow.

I have purchased other similar products before and these are the best option in this price point. The competitors are requiring you to add your own adhesive and this can cost you time and money. With these you just remove the strip and they are ready to stick and the panels don't fall off at all. The noise reduction is amazing as well.

Sure, these are easy to install, and the adhesion is good. They even look nice. Also, mine all expanded to 1” witching 3 minutes.Many physical elements are as described.But I’m sure you need these for function, right? When it says 1”, take their word for it and look at what 1” is.They are 1” at their peak. The valleys are more like 1/4”. Most of the images make them look thicker than 1/4”.They cut some of the hard wall slap back, but they don’t give you that good dead sound so you can dial in exactly what you want/need for your recording.All in all, if you want them for purposes other than recording, they may be perfect for you. For my purposes, I’m gonna spend more this time and find what I now know I need.Cheers!

Work great and stick to the wall very well. They’ve been hanging on the wall with no issue for about a month now. They came air sealed but expanded almost immediately after I opened the package. They absorb sound fairly well. Less echo in the room. I’m going to get some more to finish my space.
