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

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

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

These are awesome and easy to put up. Sound absorption is minimal, but it helps. The glue on the back is super sticky so, make sure you know where you want to put them u less your an expert at refinishing drywall.

Ekkogo means echo gone. Using 18 of these 14x12 hex panels in 4 colors per 48x56 ceiling panels has already reduced echo in my new 1,800 sqft rehearsal room with just six of the twenty panels installed so far. Four color pattern also adds visual uniqueness to the otherwise black ceiling.
