Plantronics Bluetooth Headset USB Charger

But I'm not sure about the Plantronics device. First, I had to get the cord replaced after two months, although very efficiently. Now I feel that the little earphone is a bit wonky. I only use the headset for Dragon Naturally speaking/Nuance. I like to be able to dictate to Dragon while I am walking around doing other things and also listening to programs on my computer while I'm doing something else. What I didn't like was that I had to buy a wall charger in order to charge the Bluetooth headset independently of my computer because my computer goes on to low energy the minute I stop using it and when I am using it I want to use the dictation mode, i.e. the Bluetooth Plantronics device, at all times.
