Carry both a phone stand and a headphone splitter in one small device with the Kikkerland Stand ‘n Splitter. The headphone plug slips into a suction cup base that sticks to the back of your device and props it up for viewing. Or plug it into the headphone jack and share your music with a friend.
It would be really ideal for plane travel if you could do both at the same time but I suppose you need to buy two to do that. Regardless, this is still a handy little two-in-one accessory.
