Sitting in a bus for 8 hours with 4 of your friends? You can all listen to the same exact music, at the same time, with this Belkin 5-way Headphone Splitter. All it does is plug into your music device and offer 5 jacks to stick other audio cables in.
It’s too late to buy this for this Christmas, even as a stocking stuffer, since it won’t be delivered on time. But you might feel the urge to be social anytime, so don’t let that stop you. It’s $10.
