The placement of the smart assistant button (back of the left ear cup) means that it is easy to press by mistake with your left thumb if you grab the ear cups to adjust the positioning on your head. Everything snaps off and back in with little to no effort. We actually purchased two of the racks and we are using one in the closet and the other by the front door. If you have wide feet you know how difficult it can be to fine any well made as well as comfortable sandals. JBL does not give out a lot of info on interface requirements for their speaker. I already had one of these speakers but I bought another so I could pair both for better sound. Product sound quality good. I received this waist trainer on time. Still comfy, a plus (4+ stars) The product was the perfect size to fit in a particular space in my pantry, it is sturdy and there is no assembly.
