I ordered to use one hand to hands-free kit on my Samsung Galaxy S3 (in-ear earphones provided with the S3 are a little too big for my taste) and iPod Nano (6th generation) and I'm not disappointed except for inactive volume buttons on the S3 but works on the iPod, a discreet button (between the + and - volume) allows the break with one click, or the transition to the next song by double-clicking (possibly configurable?) as well as S3 on the iPod.
So to recommend for those who still hesitate hoping it takes the shock in the long!
