So far so good. You can simply charge them directly on the headset. They sound fantastic and connect to my devices with ease. I haven't used them long enough to rate battery life, but they seem to last a few days. The only small point of criticism and reason for 4 stars vs. 5 stars is that the body of the device does not lie firmly on the left. Headset. It seems that when you press the buttons on the Bluetooth device, the connector for connecting the headphones bends. I mitigated this by placing a folded piece of paper between the headphone's body and the Bluetooth adapter's body behind the connector. See attached picture. I used folded sticky paper and attached the sticky side to the bluetooth adapter. I'll paint it black later to match.
