BXIBXI Sound Absorber - 16 Pack Self-adhesive 36 X 31 X 0.9 cm Acoustic Absorption Panels, Hexagon Sound Absorbing Panels for Wall and Ceiling Acoustic Treatment

These panels are a great addition to any setup.The quality is quite good and I feel like they will last. The adhesive is very strong and I would recommend to not stick them down fully until your happy with the positioning.Although I did buy these for decoration I did notice having these panels removed some echo in my room (especially when clapping my hands)I only used one 16 pack for my medium sized room so more packs would do a great job at removing echo / improving sound quality.They are quite expensive for the price though, that's why I gave 4 stars.

From openong these I knew where the money went (the pannels) maybe the packaging could be better but you can't expect to much for the price. The come with adhesive already on the and it's really strong. The only bad this is that it is really strong,meaning of you mess up there really hard to get off the wall without leaving residue.

These panels were bought to go on plastered walls in a fairly small space to create a room capable of recording some vocals. I avoided absorbing foam as I want the space to be multipurpose and retain a pleasing visual appearance. They take off a fraction of the top end reflections however the panels are actually so hard that they have now introduced a bit of a mid frequency resonance 'honk'.Visually they look good on the wall, the adhesive works almost too well - I tried to remove one and stripped all the paint, so now I am left with over priced expensive decorations and will still need to find a temporary solution for vocal work.

They stick well to my wallpaper and will probably ruin it when removed 😛They are light grey not white hence no 5 starsUpdateAs for effectiveness...used within a HI-FI/home theatre setting... they didn't help with the 1st reflection issues..they actually made it worse...and they ruined the wallpaper upon removal

These panels make no difference whatsoever - I’ve had them in my bedroom for a couple of years before I decided to get proper soundproofed wall installed. What’s more, when you try to strip them off the wall, they’ll take plaster off the wall with them or leave the glue behind on the wall which isn’t easy to take off. They seemed like an easy fix but not worth the money and hassle.
