Wearing the headset is very discreet and aesthetically pleasing. I recommend using the rubber tip that attaches to the inner pinna rather than difficult to hoop. I'm jogging with, and remains perfectly in place. The advantage compared to wired headphones is that the headset enters a second one hand. More Headphones son unravel painfully! To illustrate the interest, I can finally take a call when I bike, leaving the headset in my coat pocket. And no need to take the phone out of the pocket of the trousers, as the caller's name is announced. His side, the quality is correct. Rather means well, even in a somewhat noisy environment. You can use it to listen to music or podcasts. On the phone, callers hear perfectly when I'm inside or car but a little worse in urban or windy outside. This however is not insurmountable if we are not afraid to repeat from time to time. By car, I advise rather to complement the "SuperTooth Bluetooth handsfree car-kit for Buddy visor." This device, adapted to filter engine noise, distracting unless the headset.
After 2 weeks, the Jabra Extreme 2 no longer appeared in the Bluetooth settings menu on my iPhone 5S. It was impossible to find support. I would discard it when by chance, I retried successfully a few months later with the iPhone 6. I do not know what happened to the iPhone 5S. But since it works great with the iPhone 6 and follows me everywhere. I was disappointed not to find neither help nor explanations for this problem.
Last thing: it was inadvertently made 2 machine cycles washing at 60 °. After a good drying hair dryer, she returned to work as the first day.
