I searched for a way to an MP3 player cable roll up makes sense, but this wobbly plastic thing I find simply sinnfrei. Arrived there is indeed but all are just two flexible textile plastic parts, which are held together in the middle by a thin plastic pin. Wrap the cable therefore is not only difficult, since the gap in carrying out the cable is not gently spreads apart, but resists. For me too annoying. Must keep good one well that is when the cable finally there is (enough space is always), the cable before "things" in the (pants) pocket protects. for me but was crucial to find a way to keep my cable so that I need less time for the typical entrödeln, but the hoped-saving time is definitely not to be found here.
