Aune X1S 32Bit/384KHz DAC DSD Headphone Amplifier USB testing before sending We test it with a Windows PC, the Factory send a USB cable gift free, looks nice cable. Easy to use, just need to install drive at Windows, and set the sound output to "Speakers(2-aune USB DAC)". Very good sound, clear and clean. We try the Android phone too, it ask your Android have a OTG function, you need to have a OTG cable at first. Tried 2 Android phones, one is plug and play. the other phone is Brand HONOR V10 without an OTG function, so don&work.
