drivers when the OS is WIN10 or MacOS. For WIN 8 and older, please turn to
hifiman.com service & support to download a suitable driver. If connected to
portable devices including mobile phones, the lack of a power supply may result
in faster than usual battery drainage. Not all devices can be connected by USB
