> I dont think it is secure to walk around in a mall with your bluetooth turned on. (correct me if i am wrong)
You are wrong. I don't recall any Bluetooth security issues from just having Bluetooth on or from having an established connection. Those things are pretty well solved in all vaguely modern wireless standards.
The issues are always around the initial connection and key exchange. PIN-based pairing has various flaws in Bluetooth, but Bluetooth headphones use "Just Works" pairing, which I don't think has had any issues, other than the design compromise that it is vulnerable to MitM. That is vanishingly unlikely to happen with Bluetooth headphones though.
WPA2 is secure if you use a very strong password. WEP is basically extinct.
