Thanks to the 6-hour battery life they can wirelessly stream JBL Pure Bass sound and provide hands-free call management. Inside the premium housing is a pair of 12.5 mm drivers which will punch out some serious bass, while the soft, ergonomically shaped earbuds ensure the listening experience remains comfortable for long-listening hours. In addition, a single-button remote lets you control music playback, as well as answer calls on the fly with the built-in microphone, making the JBL TUNE 100BT your everyday companion for work, at home and on the go.
