This Besmelody 3.5mm Audio stereo splitter cable converts a single 3.5mm stereo jack to two 3.5mm stereo jacks. It allows you to share music with your family or friends through headphones from the same source.
In-Line Headphone Volume Control Adds convenience to any headphone that does not provide a local volume control. Simply plugs into the sound source and provides a 3.5mm jack for connecting existing headphones.

The Headphone Splitter works with any device that has a 3.5mm port, including MP3 players, CD players, and portable DVD players. Other compatible devices include iPhones, iPod, iPads, smartphones, media players, tablets, MacBooks, ultrabooks, and laptop.
