My Motorola Bluetooth earphone can last for at least 2 hours. It might be longer, but not has been practiced.

The disturbed transceiver signal could delay response time in bluetooth device, you may not be able to pick up each call properly using bluetooth headset, another issue is security problem...

Any wireless connection has security concerns, even WEP encrypted WiFi network can be easily broken in.I usually use mice to pickup incoming calls to my PC,so that my Bluetooth earphone is just an audio receiver device.

Yes, it's the same frequency as Microwave.

so, the other advantage is that you can actually communicate with your microwave by bluetooth :)

Not really, compare bluetooth device with microwave oven in transmitted power, you will have clue. The harmful radiation really depends on the current (power)...
