3. U1 is an Android Apple "little tail"
Android phones directly use dual TYPE-C cables, one end is connected to the phone&x27;s TYPE-C port, and the other is connected to the U1 USB DAC port. Generally, use Haibei to turn on USB exclusive or USB Audio Player PRO, etc. Please note that there are many Android phone models and system versions Many, not necessarily all support USB DAC output, these are Zishan can not control, you need to toss the buyer yourself, it is recommended to know whether your mobile phone can support USB DAC output, U1 only guarantees to connect to the computer.

Apple mobile phones need to buy a Lighting to Type-C cable, or buy an Apple camera kit, one end is connected to the iPhone Lighting port and the other is connected to the U1 USB DAC port, the Apple plug is the USB DAC output, and the playback software is free. If it is not recognized or used It is disconnected after tens of seconds, indicating that the deciphering chip in the pro-Lighting to Type-C cable or the camera set is pirated, and it is recommended to buy it again.
The profit is meager, and the connection to the Apple cable is not standard, and you need to buy it separately.
