DESIGN
Boston is carefully designed with the Bluetooth device placed on the back of your neck and a clip-on cord to keep the earphones in place while working out. The earbuds can be joined together magnetically so that you may safely wear them around the neck when not in use. Boston comes in several vibrant colors. No matter how tough your work out or the weather conditions, Boston is there to help boost your workout. The earphones are water and sweat-resistant (IPX5 certified).
