DEKIRU Self Adhesive Soundproof Foam Panels 18 Pack, 12''X10''X0.4'' Hexagon Acoustic Panels, Easy Install Sound Absorbing Panels for Home Recording Studio, Office, and More (Black)

These are incredible value for money. They're light but sturdy, unlike foam squares which are very flimsy. The self-adhesive backing is easy to remove and strong, so when you place them on the wall they stay put. The variety of colors means you can create any pattern or color gradient for your space. I chose a greyscale combo and it fits together almost perfectly.This isn't really "soundproofing" but what it does is reduce echo and reverberation, which is ideal if you have a small studio space in your home, or a home theater and the acoustics just need a boost. I cannot recommend highly enough.

Went on really easily and does a fair job at absorbing echo.

Es Importante saber que no son aislantes antirruido. Nunca van a insonorizar del.ruido externo una habitación. Su función es eliminar rebote en el audio y mejorar al audio al interior de una habitación. Para mi estudio estuvieron perfectas. Es necesario comprar varios paquetes (para tener mejores resultados) dependiendo del número de metros cuadrados a cubrir.

I used this in a rental unit to spruce it up a bit but when it came time to move, the hexagons left behind a sticky residue. I'd recommend using command strips or some other hanging adhesive that's renter friendly and won't leave behind residue when it comes time to redecorate, move out, etc.

Not sure how well they do with soundproofing but they helped with echo in my office and I get compliments on them a lot. I left the backing on and used 3M double sided tape to put them up
