I use it for a month. Great product, great sound both mobile PC connection. I use it almost every tps driving, and even at home when I tinker and no corresponding phone told me "I hear you bad !!!" some do not even believe I was driving. I call between 16 and 20 hours per month and with this headset I have a battery life of 5 hours on average conversation before recharging. I recommend !!!!!!!!!!
