Acoustic Panels 12-Pack Soundproof Wall Panels 14''X13''X0.4'' Sound Panels High Density Sound Dampening Panels - [Deep Black Hexagon]

Used two strip's of thick double sided tap and they have held up day 2

I used commander strip stickers to put them on my wall as they do not come with any adhesives. They are true to the color. They are soft but sturdy as for cutting sound - I would think I'd need a couple more 12 packs to cover more of the wall between me and my roommates wall. I do like the look of them and will be getting more as my financials allow it

Really really good, works quite well to dampen sound and lower echo. It's not meant to work miracles, but it certainly works the same or better than the generic foam "acoustic panels" with spikes. The material is very high quality and just feels like it was made well. These work very well as a Voice actor to make audio sound less tinny, and are a GREAT decoration that makes the room look much nicer. Doesn't have adhesive on the back, but that's probably a good thing that allows them to package it very efficiently and you don't have to wait hours for them to inflate and none of them were physically defective in any way.. Just use some good double-sided mounting tape and you'll be golden. They're not very heavy. The accuracy of the manufacturing is very good, the bevels and shapes were cut very evenly and consistently. They just feel SO high quality in-hand. They are fairly sized, they cover up a fair bit of space, I would recommend getting at least two twelve packs, each a different color. They don't have any noticeable outward smell, but smelling them up-close smelt like pleasant fresh linen. They're a bit on the expensive side, but for very good reason. You are paying for high quality and it shows.

me hubiera gustado que trajera la cita para la pegar los mosaicos

Absolutely useless. Poor adhesion with double-sided stickers, and not effective at soundproofing. Just a decorative panel that looks like a soundproofing solution.
