DEKIRU12 Pack Self adhesive Hexagon Acoustic Panels Sound Proof Foam Panels, 14 X 13 X 0.4 Inches Soundproof Wall Panels For Office Ceiling &Door (White)

It is great for design but the adhesive can wear off at times. I just purchased it and left for a few hours and some pieces fell off. I would just be mindful. Otherwise great.

I like these! Super easy to install and make cuts to fit the corners of the wall. They absorb sound well enough too.

I did not find that this product made a noticeable difference for me.

These worked great for us, and helped dampen the noise from the furnace in the hall closet.Will likely buy more to cover the rest of the closet inside.

They fell off and either took the paint with them or my paint bubbled up
