18 Pack Hexagon Acoustic Panels,12" X 10" X 0.4" Sound Absorbing Panels

Had these for probably a couple years on my wall now, can't complain about the adhesive at all! Holds very strongly and would likely strip the paint on my wall if I had to take them off, can't complain about that! These look great and are dense enough to take the echo out of rooms which allows for a better listening experience. For how much they were, I really can't complain at all, I like them! I like the look of these over the foam ones!

50 Pack Acoustic Foam Panels,2"X 12" X 12." I wanted to wait until I purchased my second set to do this review so that it would be honest and accurate. To be clear, these are not for sound proofing...they are for sound absorption just like a sponge absorbing water. They absorb room reflections but do not block sound. They're foam. One example is for vocals to keep the reverb in the room from coming into the mic. This will not keep noise like cars passing by, helicopters flying above, HVAC, or other noise from coming in hence, they will not block sound and soundproof your area. This is something that you as the consumer need to understand and accept BEFORE you purchase these panels. As sound absorption panels, they are good quality panels and work great! Also, to be clear, I am in no way telling, suggesting, or recommending anyone to NOT purchase these panels. They are good quality panels and I have had no issues with them! First thing to know that it clearly says that the adhesive tape does not come with the panels...you have to purchase your own. These are NOT self-adhesive! Second, when using the adhesive tape like 3m, you will need some additional adhesive like Gorilla Glue as foam doesn't always stick to the adhesive tape or the wall. Third, be patient! The best method is to let them set out for at least three days. The first two days is for the "smell" to air out while getting air in. The third day is an extra measure to examine them to see if any forming needs to be done. Pic 1: When then arrived and after I took the package out of the Amazon Box. Pic 2: When I took them out of the main wrapping. There are two vacuum sealed packs. Pic 3: When I took them out of the main wrapping. Since it's now unsealed, air started coming in and they already started expanding. Note: They expand quickly so prepare to get them out of the back quick! Pic 4: What they looked like 5 minutes later. Some expanded in full and some didn't and are deformed. There are two to each "stack". Pic 5: One of the "stacks" that was still somewhat compressed and deformed. Pic 6: After I pulled apart the stack that was still somewhat compressed. One panel. Pic 7. The other panel. Notice on both panel the triangles are deformed. Pic 8: Me beginning to pull the triangles gently. Pic 9: Me fully and gently pulling the triangles gently. As you can see, it's already getting it's form back. For the panels that are deformed, gently pulling the foam to get it to form helps get more air in and they will get their form quicker! This part takes patience! Those that said the panels would not take shape or stay deformed are not doing this to help shape the panels! Pic 10: All 50 Panels laid out and getting air All of this was done within one hour. They still need air out to completely form. Although the directions state 24 hours, it's better to wait 3 days. On my first set, I sprayed some Febreze to further take out the smell and will do the same to these. This does not take away their absorption properties.

Decided to try them again. still not 12 inches but made them work. I did have about 10 that would not stick so that was a letdown. First order was super sticky. I ordered enough to do a small bathroom also but did not have enough because of the nonstick ones, so I am returning some. They are easy to install and help just a bit with noise BUT they are not 12 inches. The are 11.75 and I had 3 areas to put them. Exactly 3 foot and 2 exactly 4 foot. So I ended up with an inch and a half not covered. the length of the ceiling. I would have returned if I had measured before I spent 12 hours up and down a ladder. I am going to get some trim wood to cover the space. Something I didn't expect to have to do. They do look nice and stick very good but if I have to pull them down I will ruin the ceiling. I would recommend them whole heartedly if they were as advertised.

I bought my mom some "peace and quite" for her birthday... did her laundry room and she loves it. These squares make ceilings super easy and I used 8 on the 32x80 door. Full coverage is much easier IMO but not required. Honestly once you get the first 4 up you'll likely go get whoever else is home to make sure you're not having a stroke. These panels are super bizarre as they literally create a black hole effect in a room you thought was quiet. Even sealed in the Amazon box they somehow absorb sound lol. My dogs LOVE the rooms with these tiles as the cave like stillness is awesome. These were the first batch of self adhesive panels I'd bought. They are on par with the others I've purchased as far as noise canceling/look. You can pay more for slightly nicer looking panels but now that I've heard both side by side I will not be buying the next price point up because they simply aren't worth it for me personally. The adhesive is NO JOKE you get ONE shot. Peel the backer off one edge and lay it in place with one hand under holding the peeled backer and the other hand on top of the tile holding the sticky edge in place. When you got it close peel the backer off and VERY lightly press and make sure you're still lined up. Once you press down these are permanent IMO. The adhesive is on par with self stick flooring. I did absolutely ZERO base prep... just stuckem up. The adhesive is overkill which is what I personally prefer. I used blue painters tape mark my borders and edges. If you are doing full coverage you could easily do a whole room in an hour or two max. A large HD paper cutter will cut these perfectly straight. I cut half way across and then flip it and finish the cut. You absolutely could use a utility knife and a good straight edge, BUT if you're doing a whole room get a large paper cutter. I'm using a Wescott 15in 30 sheet cutter. The trick for straight cuts is the half cut. Honestly this puts so little stress on the cutter you could return it... but that's on you. Just ordered 3 more sets for my Dad's office. He doesn't get excited about much, but they were both blown away.

I have bought these twice, and the second set developed a terrible mildew smell within a few months just like other reviews have mentioned. I had to take those down and trash them. Both sets were effective, but I used them for acoustic dampening, not soundproofing. First set went in a giant HVAC unit closet that holds a heat pump, and it dampened the sound. I used the adhesive backing and stuck these to the exposed back of drywall, they stick great even being exposed to a range of hot and cold temps. Second set went in a corner of my bedroom where the HVAC heat pump noise echoed. It dampened the echo. I did NOT use the sticky side on the drywall, I was able to use a single nail in the corner of each panel to hold them in place. They did great to cut down the echo, but this was the set that started to smell musty after a few months. I live in the high desert and it's never above 35% humidity indoors, so. This is a problem with the product and how it's packaged and container shipped. It's hit or miss, you won't know for a couple of months if you have a problem with he mold and mildew growing in the tiles. So. If you are putting these up somewhere not in your living space with the understanding these are sound and echo dampening, not sound proofing, go for it. If you want it for your bedroom, find something else that won't be surprisingly smelly in a few months.

Adhesive is far, far, far too strong. These are absolutely NOT renter friendly. I wish I had read the reviews before making this purchase and sticking them up on my wall. For anyone else who ended up in my position, here was my method: Let Goo Gone spray gel soak into the adhesive for at least 1 hour, maybe up to 3 hours and be sure to re-apply a few times. After the adhesive backing starts to pull away from the wall a little, go in with a plastic scraping device (I used a plastic dough bench scraper). Be patient, and try to peel as much of the adhesive off of the wall as possible, rather than just scraping. Use the scraper to work your way around edges and give yourself little areas to start peeling up with your fingers. This process and the trial and error of figuring it out took me about 4 and a half hours, during which I took no breaks and swore like a sailor. I’ll never buy these again. Also they didn’t even make my room less echo-ey.

Bought this pack twice, very good product. The Walmart double sided acrylic tape works wonders with these panels. They stuck for over a year and would of stayed stuck for many years if we didn't have to move. I also used T Pins where I could to keep them mounted. They sound treat a room beautifully and they look great! Will continue to buy this product if I ever need more.

The panels worked flawlessly for me. First off and most importantly they’re very fireproof as you can see from my video. Not even a direct flame form a torch can get it to light on fire. The 24 I received was enough to reduce the noice from my cello by 1.6 decibels, and that’s considerably good! The tone sounds way better as well with that slight reduction in reverb. The panels stuck very will with the full back adhesive vs the small stickers you’ll see on the competitors. Also them being easy to cut and as a bonus. I was able to use small trimmings from pieces I cut to fill and small gaps between panels. The gaps were there due to me rushing installations. All in all I strongly recommend this product. The cost is perfect for what you get.

Como diseño están muy bonitos, pero no disminuye el ruido.

Se adhiere fácilmente a la pared, ideal para contener el ruido, el producto llegó en la fecha indicada y en buenas condiciones 👍

Self adhesive is STUCK does not come off at all.

Very good

Looked good, easy to install. Turns out the adhesive is still strong enough to peel paint off the wall. Good thing I had to repaint anyways.
