These were very easy to do definitely recommend

4.0 out of 5 stars Great

M. · 7 February 2025

Came packaged all vacuum packed, sprung back to shape within a few hours, the adhesive is good, had no issues sticking to my walls, use it for streaming as my walls are very plain and can notice a difference in audio quality, not a HUGE difference, but a difference nonetheless :) will probably buy more to cover more empty walls

5.0 out of 5 stars Does the job!

Does the job! These soundproof panels are good for basic soundproofing. I wouldn’t say they’re studio quality, of course, but for a pack of 24, they’re not bad at all. Once taken out of the packaging, they puff up quite quickly—I left them for a few hours, and none were deformed or torn; all were in great condition. The sticky adhesive on the back is good quality, and after a month, none have fallen off the wall. If you’re looking for simple soundproofing, I’d recommend these. They don’t completely block out sound, but they work well for what I need!

1.0 out of 5 stars Adhesive is not sticky at all

H. · 7 October 2024

I put these on my walls, 20 minutes later, half of them are falling off. I've repeatedly been putting them back up until I felt the sticky side was barely sticking to my hand never mind the wall. These look nice and would be great, its just a shame that they stick very very poorly.UPDATED REVIEW- Down to 1 star. Here I am 2 weeks later and the entire set has fallen off the wall. Ive been putting them back up daily, used a reverse adhesive and they still wont stick, now they are pinned up with drawing pins but they pop the pins out and fall off after a while. I wish I could send this back but unfortunately they are now used. I feel like I have just paid for a headache.

3.0 out of 5 stars Pretty pointless.

Don’t think these cut out any noise. Don’t really know what they’re supposed to do. Maybe if you’re in a studio looking to reduce echoes; but then you would be using proper dampening. Maybe 3 stars is too generous.

5.0 out of 5 stars Worked great & sprang back to shape quickly.

M.C.D.N. · 22 July 2024

Bought these to reduce echo when recording my voice. My main concern when buying foam sound panels was that they wouldn’t rebound to the original shape after the vacuum packed delivery. Other people had mentioned having to soak and dry these kind of tiles or leave them for weeks - Some never regaining shape. These, however, sprang back to shape as fast as I could get them out of the vacuum bag, and were ready for use right away.Overall they are doing a good job. I’ll need to get some more to continue to get rid of the echo from other walls/ceiling, but so far so good with what I have. 👍Only slight negative is that not all the panels are the exact same size. Maybe up to 5mm tolerance. This is just me being a perfectionist though!

4.0 out of 5 stars Easy to use and stuck down well

Hi stuck well and easy to put up. Product does work to an extent in terms of blocking noise. In my situation I am considering other noise reduction options.

2.0 out of 5 stars Do not buy from this seller. Look elsewhere. Poor quality for premium price.

Do not buy these, looks elesehwere. I was willing to pay a higher price than others. However what I received is disapointing. Althought the size is as described, 50% of them are completle flat and the glue is not spreac on the whole square. Try find some other seller, avoie this one.

Very nice

Perfect living room sound boards to dullen the tv for those in the office looks nice and has made a difference

Great Sound Dampening, Creating a Unique and Soft Sounding Space!!

M. · 19 July 2025

This six pack of 2" thick pyramid shaped acoustic foam panels by Hertber, are different, but in a nice way. They came vacuum packed (as most do), but instantly expanded to full size when I opened them. Like In less then a second! Just POOF!! And they were full size. That's the first time I've seen that happen. And that's a good thing!The base of these foam panels are 3/4" thick, while the pyramid portion is 1-1/4" thick. There is no funky smell and I was pleasantly surprised by the unique amount of firmness these sound panels had. Still soft to the touch, but firm.The adhesive on the back of the panel is very strong, so be sure of their location before placing them on a wall, studio door or any other surface. Peeling off the paper from the back side is easy to do and the panels stick firmly to the wall. This particular brand of sound panel seems to have unique sound dampening qualities. Creating a nice, tight feeling, blended with a soft & quiet feel wherever they are placed.Even though these foam panels seem to be fully expanded. I always like to steam foam panels like these, just to make sure they actually DO expand all the way. I believe that by doing this, these acoustic foam panels function better and give you the full peak performance that they were designed to provide.

Awesome soundproof

Absolutely happy about these foam for my studio.I had previously bought the pyramid type for a booth and needed to get more for the walls.I really like the style of these and when their direction is alternated it looks super cool on the wall.They arrived vacuum sealed, so I left them out for a day to get back their form, although they started to form back almost right away.One thing I did notice was that they had a very strong chemical smell, I had to open the window for air and turned my fan on and it disparate after a while.I had used double sided tape to hang them and later on when I came back into the room they were all on the floor. However I think that tape isn’t the best quality. I will find an alternative.Really great quality foam and easy to use.

ちゃんと効果を感じられます

この手の商品は色々買いました。その中でもこれは裏面全体に両面テープがはられていて、それがかなりの強度です。ですのでまず貼るのが簡単と言うことと、材質にもよりますがかなりしっかり接着されます。測定器を使って部屋の定在波をやっつけようと、いろいろ試したところ、二枚重ね、あるいは間に別メーカーの分厚い吸音材を挟んでみたところ、かなり効果がでました。今は天井にパンチングボードを吊るして、その表面に貼っているところです。果たしてどれくらいの効果がでるか楽しみです。凸凹したウレタンとうまく組み合わせば、そこそこ気に入る音が手に入ると思いますよ。なんといっても両面テープがすでに貼られている点が作業を楽にしてくれます。おすすめします。ただし、セールの時ね。

Good for echo in rooms

Use a heat gun or hair dryer to get them back to shape. They expanded pretty quickly from being flat packed. These were slightly larger than the last batch I purchased unfortunately so it messed up my pattern a bit.
