    I received my XP-2 Pro unit today and it is sounding completely mono. I have tried:

    • Connecting on Windows (with the drivers) and Linux through USB;
    • Connecting through AUX input to a working source;
    • Connecting through Bluetooth;
    • Using different headphones;
    • Changing settings on Windows “xDuoo USB Audio Device Control Panel”.

    Looks like the unit is working fine, but just don’t want to play stereo. There is samething that I can try to fix that, like force firware update ?

    Hello. I had tested with differents cables and with the 3.5mm cable that came. And as you say, I checked now if it’s properly plugged, same results. I ran more tests and found some interesting behaviors:

    • I got a RCA to 3.5mm cable and use it to connect the XP-2 Pro to an external DAC through the line-in, to use it as an amplifier. The XP-02 Pro is taking each RCA channel and pushing two both sides of the headphone. So I can watch videos (mono sound) with only one cable of the RCA pair connected. And listening to music, I can hear each recorded channel by unpluging one of the RCA cables.
    • Some user told me that the line-in port can act like a line-out too. So I did one more test turning the XP-2 Pro into USB DAC mode and connecting my headphones through the line-in port. As results, I checked that there is a separation through that port, but not completely. When I play a specific channel, it sounds in full volume on it, but in the other channel I still hear clearly the sound in half volume.

    I checked all the functionalities of the unit. USB DAC mode, amplifier mode, bluetooth controls. Even the microphone is working, actually it is a really great microphone for a bluetooth device. But the “mono behavior” make it unpleasure to listening to music.

    Found that prices for international shipping are a bit bureaucratic and costly here, from my country (Brazil) to China is over U$50, depending on the package dimensions. I purchased the unit on a Aliexpress store and I still making use of (videos through bluetooth Aptx Low Latency). So, should I try a partial refund on the Aliexpress platform ?

    A doubt about other product. I bought a XD-05 Basic from this 11/11 but didn’t find information about the “optical input” connection type on the product advertising. I have a optical cable but it have square connector. Looks like the advertising shows images with a diferent type of connector, it is a proprietary cable ?

    Yes, the DIGITAL IN of XD05BASIC is supported coaxial input and optical input, it is 3.5mm round  optical fiber or coaxial
