50 Pack Acoustic Panels Soundproof Studio Foam for Walls Sound Absorbing Panels Sound Insulation Panels Wedge for Home Studio Ceiling, 1" X 12" X 12" (50Pcs, Black&Blue)

I really like these they look amazing in my office and really transformed the place as well as providing some shelter from the loud groanings of my 3D printer humming away in the other room. Sound suppression is evident. They also add a small amount of insulative value to the room. A cheap DIA makeover for sure! There's no smell after putting them up I guess I don't smell anything from them. They've held up now for several weeks and no issues. The foam cuts nicely and looks uniform and I have no issues with its quality.

Good quality for the price

These were a present for my nine year old grandson for his bedroom and he absolutely loves them.

They do have a chemical smell when you open the package. Sometimes it can be quite strong. When it is very strong I use the manufacturer suggested prep and let them soak in hot water for about an hour or little more. Then lay them out on a flat surface individually for the overnight. When I return they are definitely poofed and all smell is gone. I see reviews of people who use double sided tape and Velcro to attach to the wall or ceiling. You have to remember that sounds cause things to vibrate. The louder the sound the stronger the vibrations. most double sided tape warns against using in areas with loud noise. Velcro holds a little longer but those glued surfaces don't stick well to porous surfaces. I have installed every set with my staples gun like you would use for construction and my first studios foam has been installed very solid for nearly 15 years with no problem. Remember, these are foam and will absorb every bad odor they are subjected to. If you have people smoking in your studio that will stay forever. I have a guy in studio 3 that burns continuous incense and even when it's not burning the room smells like it is. These 1 inch squares aren't designed for A1 level studios. These are for your home studio or a kids playroom. They can be used as a secondary form of sound deadening products when you are using 2 or 3 forms of deadening products in a room or studio. They work great on ceilings right up against the wall where sound waves reflect off the wall at an angle and caught by the foam shapes. For lower on walls and in the middle of the ceiling its better to use the 22 inch squares that have pyramid shapes covering the squares or larger sections of egg crate foam. Using these as intended, I have never been disappointed in what they do. This seller has them at an excellent price. Buy a 50 pack from a music studio supply store and pay 3 to 4 times this price for the identical product. I just ordered 3 more sets for a studio I'm doing in Cincinnati Ohio in a few weeks. Don't go in expecting these to be your primary source for deadening and use the proper mounting hardware and you won't be disappointed.

The product states it blocks out noise, well these are thin an thick the thickness varies. These will NOT dampen or drown out the noise you wish to not hear or want people to hear. Better yet if your going to get these, get some styrofoam sheet as well, grab some FlexGlue & put them on the Styrofoam sheeting, then take your FlexGlue an apply to the back of the styrofoam sheet, press firmly let dry, its not going to come off an the noise will be dampened. This is more for rooms that are already sound proof'd but you may have missed a " spot " around the door or corner. Pro's : none Cons: cheap, not as effective as stated by seller! wouldn't buy again!
