Sound Proof Panels for Walls, 17"×11"×0.4" Self Adhesive Soundproof Wall Panels, 12 Pack High Density Acoustic Panels,Soundproofing for Recording Studio Home Offices (Gray)

Very good quality and look very nice! Super easy to put on the wall and the sticky part actually sticks.

I recently got a set of these acoustic panels, and overall, I’m pretty happy with the results. These panels not only look great but also do a solid job of improving the acoustics in the room. The design is sleek and modern, adding a nice aesthetic touch to my space while also serving a practical purpose. The self-adhesive backing is legit impressive—it sticks really well, even on a rough sand-plaster finish, which is a win for anyone dealing with less-than-smooth walls. The installation was quick and easy, and once they were in place, the panels immediately started making a noticeable difference in the room’s sound quality. They definitely help deaden the noise and improve the overall acoustics, making the space feel more comfortable and less echoey. That said, as some other reviewers have pointed out, there is a slight chemical odor when you first unpack them. It’s not overpowering, but it's noticeable. Thankfully, the odor dissipates within a few hours, and it’s really best to open them outdoors and let them "breathe" for a bit before installation. After that, there’s no lingering smell at all. In conclusion, these acoustic panels are a great combination of form and function. They look good, are easy to install, and effectively improve room acoustics. Just be aware of the initial odor and give them some time to air out before you install them. Highly recommended if you’re looking for stylish and effective soundproofing - you won't be building a DIY anechoic chamber with these, but for streamers or home recordists - or just people working remote - these are great.

To be clear, I didn't go into these with any higher expectations than what I got out of them; they're merely a thin acoustic panel. They are most definitely not soundproof by any measure. If you're seeking to soundproof an area, it's best to look elsewhere. HOWEVER... If you're after a product to lessen the sharpness of higher frequency tones in a room, these can be of help. I had pickled up this set of six panels to utilize in a couple of corners of my office/studio, and possibly to build a small voice-over recording box for my microphone, and as such, they're not bad! The smell of the materials dissipates quickly with a night outdoors, and the adhesive isn't exactly strong, so I can see having to spend some time rectifying that with some 3M-type adhesive strips or Velcro, should you wish to mount them more permanently. I'm presently just leaning them at an angle to reduce the reverb off of a corner, and in that sense, they're doing some good. Considering these as what they are, they're alright. Considering them in light of being something better in terms of sound control, there are probably better options out there. Overall, not bad for reflecting some sound and controlling the acoustics in a very small studio.

We added these on a wall we installed to divide a section of our home for a private guest space and block the sound of us going up and down our wooden stairs. These panels do help with sound carrying but are not completely sound proof, though to be fair, we have not covered the entire wall. The pattern is more vivid in person than expected and it looks nice in the gray color. These panels are also in black or white in packs of six or twelve. The adhesive needed a bit of help to stick to our plaster walls, so 4.5 stars.

First, how effective these will be depends a lot on the room, the noise level, and your expectations. If you have ever noticed how lively an empty bathroom is and how much that changes by adding a couple of towels and a floor mat, that is about how much these products will help if you are using them in a fairly small and lively space. The larger the space is, the more panels will be required to make a difference. Second, calling them soundproof is a little misleading. Absorbtive sound panels like these do almost nothing to reduce the sound traveling into a room and only slightly reduce the sound traveling out of the room because they reduce the noise level in the room. These appear to be made with compressed felt and are dense, as the description says. Due to their thin construction, they will mainly reduce the higher frequencies in a space but won't do much for low frequencies. I am using these, along with some other acoustic products, in my basement hangout space to help reduce the noise, even though there is a lot going on.
