5. What's the difference between the two micro USB ports on Q5?
A: The micro USB port on the side is used for charging and Bluetooth update. It's recommended to use DC 5V/1A(or above) charger to charge Q5.The micro USB port at the bottom is used for USB DAC connection with computers or Apple's devices and firmware update.
Note: The USB port at the bottom could be used for charging too, however, the charging current would be relatively lower and charging time would be longer. So we don't recommend to use the port at the bottom for charging.
