Put this on a office glass that shared a tv Amazing difference Easy to use and very professional looking A+

I bought these panels to help sound-proof a small, casual podcast space in my home office. The room isn't huge, and these panels covered a decent amount of wall space behind the chairs. The panels were very easy to install. They are self-adhesive, and all I had to do was peel off the backing and stick them to the wall. No need for nails or screws. I wouldn't say these panels completely soundproofed the room by themselves, but they did noticeably reduce the echo. The real strength is how awesome these look! So, combined with some more standard foam panels for other areas out of sight, these panels really help to elevate the look that you may be going for. The panels seem well-made. The foam is fairly firm and doesn't seem like it would easily get damaged. If you're looking for an easy-to-install solution to reduce some echo in a small room, these panels are a good option. They are relatively affordable, easy to use, and most importantly, look awesome!

Great Job will use again on a larger job
