It has a 4 part mini phone plug.
On the cable there is a white plastic block with a + on one end and a - on the other. No idea what this is used for. Seems it can be clicked, but otherwise has no effect.
I thought I was supposed to alter playing back of music - stop, pause, start, change volume. There is absolutely no documentation anywhere on this (short of spending a week searching). The 920 manual doesn't mention a word. Nothing about them in box.
So - what is this white thing that does NOT change the playback volume of music nor videos? How can I or can I control music playback, skip to next track, play, pause etc with these in box ear buds?
Please bring back the day when documentation existed and wasn't an afterthought. Most of the software on the 920 - I have to guess how it works. There is no doc on the phone nor on line.
