USING THE STEALTH
Prior to using the headset i strongly recommend heading over to the official Jabra support page to download the latest firmware version (they update the firmware of their headsets quite often).
Once you connect the headset to your PC and launch the firmware update file it will display the installed firmware version and the one you will be updating it to.
After that the firmware update program will install the necessary headset drivers and will proceed to upload the firmware.
The entire process takes roughly a minute to complete so again i strongly suggest doing so (firmware updates are not for show, they correct many bugs and even improve on audio quality and battery life - sometimes they also add new features).
