I measured myself before ordering and checked the sizing chart. Microphone and Ear doesnt function. Has options for left or right ear, a mirroring option, and portrait or landscape. That said, these are probably overkill for a phone or tablet and are designed more for home system listening. Been looking for something like this for ages - a kind of slipper I can wear round the house that doesnt have a heavy, flappy sole and that lets me feel the ground beneath my feet. This set was perfect, and looks great in the location we wanted to use the sets. 60+ dollars for this thing and it?s broken. Otherwise they are a good slipper and I think they will hold up well. This came brand new in the box, exactly as it would come from Harman Kardons own website. So, lets try these.
