Acoustic Panels 12-Pack Soundproof Wall Panels 12''X10''X0.4'' Sound Panels High Density Sound Dampening Panels - [Light Turquoise Hexagon]

Helped reduce the noise in my office but I needed a lot of them!

These are awesome. I ordered two sets after moving into a new home office that has a lot of echo to it. I added carpet, helped some but not enough. The room is big. I'm a podcaster and was looking for a solution. I thought I would end up recording in my closet. But no! I wish I could upload sound files here so you could hear the before and after. I just have them on the wall behind my mic and it's a clear difference. I'm ordering more for beside my desk. I put them up with teeny 18x 3/4" (1.2mmx19mm) nails like someone else suggested and they went up so easily.

Wonderful for creative placement and holds up well.

These are very good quality however they do fall off the wall randomly as the adhesive is not strong enough

I bought 4 packs on three different days. All 4 packs were the same size, no problem. They were easy to cut with a box cutter. I used 3m double sided foam tape to stick it to the wall. It insulates the outer wall and provides sound dampening; it is a win-win.
