I was looking to improve the acoustics of a small corner of my home, mainly for recording videos and taking calls, and these panels solved the problem much better than I imagined. In addition to reducing echo, they made the wall look beautiful with that natural oak slatted effect that is so trendy right now.
Installation was very straightforward. It was just a matter of measuring, aligning, and sticking them on. The adhesive backing is quite strong, so it is important to position them correctly before pressing them fully onto the wall. I installed them by myself and had no trouble at all.
The felt material is lightweight yet firm. It does not look cheap, it on the contrary, it gives the room a modern and cozy feel. It looks perfect in my office, but I can also imagine using it in a TV room or bedroom.
Regarding the sound, I noticed a significant reduction in echo, and the room feels more acoustically tight, especially for recordings and online meetings. A quick tip: clean the wall thoroughly before installing and mark your alignment with a pencil or tape to ensure everything stays straight.

Quick option for wall accenting!

These panels are very convenient! They are extremely lightweight and easy to handle. Cutting then is very easy and can be done with a straight edge and sharp utility knife with no problem at all. Just make sure that your layout is good on the first panel and every thing else will be a breeze. However, if you do mess up, the panels can be pulled back off fairly easy, if you haven't pressed them in hard on the initial set. If you pressed hard right away, good luck getting them off easy!

These acoustic panels offer a stylish solution for improving sound quality and enhancing your room aesthetics.

I've been looking for something to put behind my TV as time goes on. One tends to go a little larger each time! I had originally had a TV mounted on the wall and no matter what I did I couldn't get it seamlessly painted to match the rest of the wall and I wasn't in the mood to repaint my living room. This really fit the bill for me! I needed something to cover the blemished wall but it needed to be thin and not really super noticeable. These tiles were so easy to install and as you can see by my photo they're perfect for behind the TV and also will help with soundproofing. Easy as 123! You simply peel off the back. Stick it to the wall or to the surface. Once I got the top three lined up and level it was easy just to put them all in line and within 10 minutes the whole thing was done.

Absolute junk. Not as pictured or described. Definitely returning.

Well I think we found a winner. These are thick.
And on top of it, they actually do WORK.
So, I tested it. I played a constant 140hz tone creating 82dB of sound through one megaphone speaker.
I put one over it - 55dB. WHAT! If you hold this to your mouth and yell, you instantly feel your voice vanish.
Now, other acoustic panels do this also, but not at this price.
This is a good value for these you get a good bit of them, you don't get the false claim of "12x12" like a lot of them.
It measures true to size, it does work, it's durable, it sticks to the wall the first time (and doesn't come off).
Looks great, quality product. Would definitely recommend these.
Also, I put two under a subwoofer it actually dampens a lot of the vibration from the subwoofer.
These really are great, they are better than others in this price range that's for sure.

We like these 8-pack acoustic Peel and Stick Acoustic Wall Panels. They come as advertised: 11.8" x 11.8". Made out of PET Soundproof & Noise Cancelling Acoustic Felt. We liked them so much that we bought another pack on our own to complete our DIY Home construction project that we have been working on ourselves. These panels make our entertainment center room a high-quality sound fidelity mini acoustic studio. BRAVO! The padding is over an inch thick, so it helps with sound as they each got a wonderful thickness and strength to them and come in sizes from 11.8" x 11.8". The ones we got come in a teak color, a dark walnut color, and grey color -- whichever suits your needs... For us, we love the dark chocolatey look of the dark walnut panels. These felt panels provide us the sound fidelity we need for a very good experience watching TV or playing video games with the kids. We recommend 100%. These are thick, and extremely functional at muzzling sound from the outdoors, and a good value for the money. These are the best. Do not hesitate to get them. This not only gets 5-stars from me... this gets my RARE TRIED+TRUE 5+1 BONUS STAR Rating for a total of 6-stars! I only give 5 stars to products that I use and exceeded my expectations for quality, functionality, ease-of-use, premium appearance & looks, durability, ease of installation & time to build, good value for the price point, accuracy in size & fit - and when possible - sustainability, green certification, safety, & environmental considerations. And my rare 6 stars rating goes to companies that bring a product that is truly INNOVATIVE and superb to have! I hope you gain some insight from my review and I appreciate you taking the time to read it.

Perfect all the way around!!

Panels are the advertised size, stick easily to walls, and help with sound absorption in small spaces. Installation is straightforward, just peel and press. They feel lightweight but hold up once mounted.

These are really thick. The wood looks almost like real wood but not quite up close, but still better looking than regular vinyl. The padding is over an inch thick, so it helps with sound. Since it's so thick you can easily nail these into the wall if you wanted to make sure they last, and put the nails in the ridges in between to hide it. The stickiness is decent but because they're so high quality and heavy and thick, I prefer to nail them and not trust the stickiness over time. They are very strong though and can withstand scratches and picture hanging and such on them.
