Easy to use
They arrived very quickly after ordering and i have tested them out in different settings they do block out a lot of noise if you have them in 100% correctly if not in correctly you just need to reposition them to get best noise blocking. They are easy to use as well.  The only down side is they came with minimal instructions and they dont say which ear plugs to use for which noise to block out.  After playing around some with them the round disks work great for keeping water out and the blue ones where the quietest next is the orange and last are the grey ones.
