DEKIRU Acoustic Foam Arched Sound Proof Foam Panels, High Density Fire Retardant Studio Foam Wedge, Sound Proof Padding for Home Studio Acoustic Treatment Wall Decoration (12 PACK 2" X 12" X 12")

The quality of the material is pretty good. It doesn't feel like cheap or something like that. The 3M strips are a little bit tricky to use, but they work pretty good once you figure them out. Besides, using the water recovery method you can get them running in no time, instead of waiting 24-48 hours. I've bought two times from these guys (first a 12 pack and then a 24) and I've had no trouble.

These work right out of the box without water. I went to walmart to buy 3M sticky tabs and still stuck to the wall over 2 months. They seem to absorb sound where I have them placed, in front of my computer. I really like the way how it creates ambiance feeling and dark walls makes my room feel more interesting.

Rebuilding studio and needed some inexpensive sound proofing in shed. These seemed to be a great option-fair price, good reviews, panels didn’t need to be soaked to uncompress.They do what they are supposed to do once you get them on the wall. 3M strips that are included are inadequate to say the least and don’t keep panels on wall. Used them only to find half of the panels on floor next day.

When I got the panels they were squished pretty tight. I followed the directions and let them sit for 24 hours and they expanded to full size. They were easy to work with and have really made a difference in reducing noise coming from outside my office.

the 3M tabs they include are a major pain to use, takes about 5 minutes to strip the very VERY thin cut backs off them to be able to use them. half the time you end up splitting the paper. plan on buying additional adhesion if you order this. EDIT: put them on the corners and then bend and scratch the sides and you can fully install them, takes a long time though

The look good, and are the full 2" height. strong enough for me to bathe in a tub and wring out without any tearing or cracks. I will be buying more in the future!

I'm not really sure what good these would provide in any situation. They're not really sense enough to do anything. Perhaps, they may slightly take down high pitched echoes but that's a stretch and my ears could hear the difference. Would not recommend.

This 2in foam was great for setting up my youtube studio! Love it. Don't bother with the cheaper 1inch foam. It is really not worth it.

They are great panels for the price. Don't expect this to fix your room sounding issues, but they look good and they help.
