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

Great product and received them in a box so all panels were safe. Love them in my music studio.

I Brought two packs of these for my new in home studio and they work great for recording vocals. I suggest buying some adhesive if you don’t want to put holes in your walls. I used clear thumbtacks and you can’t even see them because of the ridges! I Definitely Recommend these.

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 : noneCons: cheap, not as effective as stated by seller!wouldn't buy again!

This product worked great for me and was exactly what I needed. It was an easy process as far as the installation goes plus it looks awesome in my studio.

Applying adhesive to the back of these was a hit or miss since they had a tendency to peel away or fall off. For easier way to apply, I decided to make strips of them in a grid pattern and hot glue a piece of ribbon to the end, that way I just have to worry about adhering fewer pieces. Plus they roll up easy when I want to take them down. It blocks sound great and it's a better alternative than breaking bank on ones that come with adhesive on the back.

These are good but not has thick as I thought they would be

Really thin lol. No adhesive but that isn't an issue for me as I'm using gorilla wall putty anyway to not leave a residue. Personally I'm going to pay a few dollars extra and get the "BEEQUIET" brand as I think they look better and are also thicker providing slightly better sound dampening if I had to guess. I'd recommend trying them both from amazon and choose for yourself. But I immediately returned these.

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.
