I'll raise you. I once Bought a new set of headphones that came with miniUSB that plugs into a volume knob which itself plugs into my desktop via USB 2. It also came with a miniUSB to 3.5mm adapter. Just this morning I was pulling them out of my backpack getting off the train and noticed for the first time (I've had these headphones a year) there's a discreet 3.5mm headphone jack. You know what didn't come in the box? A 3.5mm headphone cable. Which means if I want to plug this thing into an old iPod or my docking station at work, I'd need to bring a miniUSB cable and an adapter. Or just go buy my own 3.5mm cable. Very interesting design choices if you ask me.
