These are good quality boards. They're thicker than I thought they would be, and line up perfectly. The backing is crazy sticky, so be sure you have them where you want them! I put them opposite my front speakers to soak up some sound bouncing around.

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.
