The official application to retrieve from the Jabra Playstore Google is very intuitive and allows simple adjustment of all parameters of the headset with the presence of a battery indicator icon in the toolbar at the top has détat left of the smartphone, quite convenient.
Attention by cons, parcels received in German and therefore obliged to visit the official jabra.com to retrieve the latest firmware software of the headset in the desired language (in French so) and flash the headset for orders French. It's very simple, just plug the headset on the PC and dexécuter the installation package ready firmware and let lopération that lasts a few minutes to get a headset entirely in French and operational.
Autonomy is really nice: my M155, it does not exceed 4-5 hours and I often find myself having to recharge during the day. On Jabra, you can almost take the whole day of intensive use with its 8-9 hours. The NFC apparatus is practical and is used only one time since when paired to the smartphone, when you turn the headset, it instantly connects to the mobile.
The pack comes with a car charger and a mini micro USB cable but no charger sector against. 2 extra ear tips are also provided and I advise you to try the 3 as suggested in the instructions for use to find the best solution and especially the more comfortable not to have ear pain throughout the day .
Voice commands respond quite well. In short, I have not found a glaring flaw that jumps to the eyes if not on one hand the touchpad has the back of the headset that lets you change the volume, a bit confusing at first with this first aspect may notched convenient but also functional and also an apparent fragility particularly at the pole that must be made to turn on the headset, you have to be cautious and be careful not to damage it.
Brief overall very satisfied with this purchase to recommend for those seeking a headset for intensive professional use.
