The Jam Unleashed consists of two individual earbuds, which do completely without any cables. Being so small, they are optimally suited for sports activities and listening on the go. Thanks to their ergonomic shape, they fit securely in the ear and give the user absolute freedom of motion. The rechargeable battery powers the earbuds for up to five hours. They are recharged in a carrying case simultaneously serving as a backup battery, since it is capable of recharging the earbuds up to ten times before the battery itself requires charging. Other mobile devices can also be charged via the USB port.
