Cambik 6 Pack Wedge Acoustic Foam Panels Soundproof Studio Wall Tiles Sound Absorbing Home Studio Office Insulation Fire Resistant Sound Proof Padding Sound Treatment Foam 12”X12”X2” Black (Pack of 6)

I love these panels proper cutting, proper size of pyramids and easy to install.Packing with vaccum without air in bag and i also make a vocal booth to test these panels.I put my mic under vocal booth or box and then i record vocals , damn , not a single reverb sound reflect from these .All frequencies and waves are captured by these panels .It's value for money to record any vocals, instruments without unwanted reflection.One suggestion for all , is please install these panels with double sided tape because if you want to remove these panels or want to reuse on other wall or place them , with tape they do not harm your walls by removing or do not damages during removal from walls .These are damage when you install with adhesive and remove it.Thanks

these panels are just thin as a foam sheet. only show piece not absorbing any sound. cheap quality foam not worthy
