Jabra Classic is as straightforward as headsets come. Besides the on-off slider, you have volume controls on the headset on the side and a centrally placed answer/end button on the front – all easy to reach and use. Headsets need power naps too. The battery saving mode in Jabra Classic turns the headset off after having been disconnected from your mobile device for a full four. And to wake your Jabra Classic up again, just press the answer/end button.
