When the battery is almost empty, it will warn you 2x then it will turn off in matter of what seemed like to me as less than 1min. I thought they might get in the way, but they don’t. Nice little tech here , Ive said after one day of use. UPDATE: Its only been about two months, but I figure I should pop in and say that this charging cable still works great! This is also my first bluetooth headset so I cannot say how it performs compared to other products. This is not for you. They are used as everyday "run errand" shoes and house slippers. , y cómodas. its going straight in the trash bin. I also called Sennheiser Customer Support with pre-sales questions - they were more than willing to answering all the questions I had.
