as many of you already know, the barracuda hp1 headset draws power through a USB port to power its built in amp. normally a USB 2.0 port is limited to 500mA, so that puts a damper on how much current the amp can use. however, i have a gigabyte motherboard with their "x3 usb power" feature, which allows 1500mA on USB 2.0 ports and 2700mA on its USB 3.0 ports. i'm wondering if this increase in current would result in better amplifier performance, or it would make no difference at all. can USB devices control how much current they draw?
or, maybe the headphone would blow up, but i really don't see that happening. currently the headphone is powered through an ipod wall adapter, since my old PSU doesn't output a clean 5V rail, which showed up in faint rumbling noises when i scroll on a webpage, for example.
