Bought for sports (jogging) these headphones. Have tried all sizes, not fit my ear size 8 shows a too big, too small 2). The bail is too stiff, the headset is to me several times completely fallen off ear during light training. With my old 2 euros headphones me is that never happens. Promote it anyone - in any case not before you've tried it in your own ear. Sound no longer relevant, since they are unusable for Sport on my part.
