The media could not be loaded. I was looking for an affordable alternative for the more expensive formed tiles. I figured for the cost vs the number of items in the box what’s the worst that could happen? Send them back! To my surprise they are very easy to install and have a very high end look for a very low end price. Highly recommend for any room in a house to make a statement. Mine was in a garage.

First and foremost - If you are a professional musician or studio owner - look elsewhere and do it quickly.False advertisement 1) False NRC rating. I do not believe the NRC for these tiles is .95. I believe this is false advertising, and the seller should provide objective proof as to the NRC advertised, and in what frequency range this reduction coefficient exists. They do not currently do this.False advertising 2) False Density rating. The NRC rating is achieved in large part by the density of the material of the tile. It is obvious by comparing these to well-made .4" acoustic tiles of similar material, that they are not the advertised 230 kg/m3 density (507 lbs per cubic yard). They are NOT EVEN CLOSE to this density. This is the primary reason I purchased these over other tiles (like Dexmoko, who - BTW - is honest and makes a well-made tile at a 390 lbs/m3). These are likely 220 lbs or less, which is 100 kg.In addition ...- They are packed extremely poorly. There is ZERO attempt at protecting the health of these tiles as they travel, like most other sellers, who cover them in plastic to preserve them. See photos.- They have serious quality control issues with both color and refinement. See the rough edges, markings, and bubbling on the adhesive back in the photos.I will be returning ALL of them, and suggesting to Amazon to discipline this seller, and require them to advertise their products honestly.

As entry level it is pretty good.Ive been puchased this product as my first one in noise absorber stuff.I had a noise echo in my study corner, from the window of my room.After placing those panels, it reduced significantly the echos from noise and speech.Now the study corner in way more comfortable than before.As for the adhesive, it is strong even for not so smooth wall like mine.Very pleased from the quality at this price, and ill buy more to complete the look.

I used this to construct a small vocal booth. It looks really pretty with the white from the inside. And it is sturdy as I have carried it around and set it up in various places, including in my bathroom. The sound quality is good.

I don’t think they do much, if anything at all. They look nice but a 12 pack doesn’t cover a whole door, so I got two packs. They’re different shades of white. Not a big deal but weird. There doesn’t seem to be any difference in sound muffling. A waste of $70. Left a terrible residue behind that not even goo gone could easily solved. Spent hours spraying and scraping.

They were easy to use but just a bit challenging when you have to cut them. Needs a very sharp blade.

I thought everything was great with these until I had to remove them when I moved apartments.The ENTIRE WALL underneath was COVERED IN GLUE!!!!I had to spend HOURS of my time PAINFULLY using Goo-Gone and scrubbers to get it off.I had to resort to SCRAPING THE WALLS! I'm definitely not getting that security deposit back now.DO NOT BUY!!!!If you do, do yourself a favor and throw them out or leave the backing on.
