Share music with others using this three-way earphone splitter shaped like a tree branch. The Branch Earphone Splitter by Kikkerland, can be plugged to any standard 3.5 headphone jack and will split the signal into three so you would be able to share what you are playing on your portable device (mp3 player, iPhone, etc) with other people. Alternatively you can use it to hook multiple powered speakers to a single audio source. The Branch Earphone Splitter also comes with a removable cap that can be used to hang it your keyring.
