Stairville Sound Abso 500g/m² 5.0x3.0m Bk

I set up the curtain to split a room in 2. There was music playing on the other side on a Bose speaker when I pulled the curtain for the first time and immediately I could hear the difference. I yet have to try it when playing drums as it covers the door as well and need a test subject outside the room but I'm confident it will help.
I took the 5 x 3m. it's a bit long as my ceiling is only 2,2m so it's draging on the floor and makes it heavy to move but that's the purpose I guess. The look is fantastic. I only gave 4 stars as it does feel a bit like a heavy fleece blanket and catches dust very easily.
