I haven’t had time to get these put on a wall yet, but from what I’ve already seen I’m pleased with them. The wood color looks as pictured online to my eyes. The build quality is very sturdy (although these are still very long boards so you do have to be careful about bending or breaking them). They were packaged well for shipping, including individual corner blocks for each corner of both panels. The foam backing is quite thick, at least 14” and possibly a bit more. If you want to use these for the sound dampening property, this will very likely work. 

I didn’t necessarily expect them to, but they didn’t come with any hardware necessary to put them on a wall. The instructions provide a few options for hanging including gluing and screwing into wall studs. I’ll have to figure out what the best approach is in my space, but I do like that it gives you the instructions for a few different options.
