So here's the deal. I connect my Stiletto 2 to WiFi in my house, then I connect the Stiletto to the computer via USB, then I play the Stiletto through headphones thanks to the headphone jack. Am I: Using power from the Stiletto battery? Using power from the computer WITHOUT recharging the Stiletto? Using power from the computer AND recharging the Stiletto? Something else? If this question isn't answered by the above ones: Also, is it possible to recharge through the computer just by using the USB? How?
