JABRA EVOLVE 40 MS MONO NC MON

Features world-class speakers that are built for both voice calls and listening to music. Switch easily between conversations and listening to your favourite tracks. The in-line call controller gives you easy access with large buttons and LED indicators, and the discreet boom arm can be tucked away into the headband when not on a call. The integrated 'busy light' turns red to let people know when you're on a call. It can also be turned on manually when you don't want to be disturbed.
