These Sinfonian earbuds are the perfect traveling companion for any music lover or just the casual person on the move. Designed to work with almost any standard audio device with a standard 1/8″ stereo headphone port, these stereo headphones have the added benefit of being designed specifically to be as portable as they are convenient. The small size of the earbuds is great for pocket, purse, or travel bag. These headphones can be extended to an astonishing 48″ in length by simply pulling the retractable cord until the self-locking mechanism engages. Another simple tug will retract these back to the 2″ housing with little effort.
