wtf, how will that help? The headset will still draw power from the battery itself.
And cellphone use cannot be compared to something like this. If it needs to recharge every 2/3 hours that means there will be more charge/discharge cycles. And charge/discharge cycles are what kill battery life. On the contrary I can go without charging my phone a day or two and perhaps even longer if I'm not using it much. Plus I can change my phone batteries is they die.
