It may or may not be an issue, but please confirm if you measured voltage or current. I know you wrote "current" but I want to be double sure. Either way, how did you measure it, and what was the measured value, in Volt if voltage and A, or mA if current, obviously. Also did the value change it the unit was power off, but still plugged in, versus power on, that is when you actually using it to listen to something.
