The Yurbuds Armband makes a great companion to Yurbuds Earphones. The armband is made from an ultra-soft neoprene material that stretches to give a secure fit while remaining comfortable. The armband fits a majority of smart phones and music players, plus it protects them from sweat and moisture. A YurSafety ID is included, which is a custom engraved key with secondary contact information and medical notes in case of an emergency. Compatible with the iPhone 3, 3S, 4, 4S, iPod Touch and many Android smartphones.
