30 cm x 26 cm x 0.9 cm, Pack of 20 Acoustic Absorption Panels

I bought these to stop the noise of my neighbour as they made love like young people but combined with her being a screaming banshee..... I put them up and then they moved out the next week.... unlucky / lucky for me BUT they do look good on the wall and it’s become a feature wall now that I’m not going to cover up 😆

These panels work really well.Can make your HiFi sound way better.Each panel comes with an adhesive backing with a devilishly difficult cover to peel off.I put these up with the adhesive backing that comes with them (attached) and they all fell down within 4 days. That's not a failing of the panels at all - the backs are really sticky but they will fall off.Got some proper contact adhesive for these and they make a huge difference, sound wise.It's a thick tile that lines up brilliantly, looks good in geometric patterns on a wall, has contoured edges, get them in tight and check every tile with a spirit level as to be able to make micro adjustments.Acoustically impressive, fairly cheap hex panel.It's also quite nice to look at as well - when installed properly.

Wouldn’t stick and fell off the same day

No difference, used two packs for a small room. The way the discs come with the sticky backing means you cannot remove them without destroying the paint on the wall.
