    It will improve the SQ, only if you really want it to. [​IMG] The plain answer is no. You would probably save plenty if you bought a reasonably priced cable + a spare cable for a backup.

    I also have a Z3c (D5803) and the only way to connect it is via the headphone jack to the Fiio E12A is to use a short M-M 3.5mm cable that is probably included with the E12A, not sure, I don't have an E12A but my E07K and E17 both included a short M-M 3.5mm cable.  You will be double-amping in this case but the headphone output will be outputting proper 24/96 (if that is what you are playing) audio ONLY if you use the stock Walkman App/Player or something like UAPP or HibyMusic player.  Using any other music playing app (e.g. PowerAmp, Neutron, Google Music Player) will result in the music being up- or down-sampled to 16/48.
    If you don't want to double-amp then an external DAC/Amp combo (Fiio E07K, E17, or E18) would also work but the same limitations apply.  If you want true 24/96 or 24/192 playback that is not up/down-sampled to 16/48 then you have to use the Walkman App/UAPP/Hiby players.  The only caveat is that the awkward location of the microUSB port on the Z3c (and Z2/Z3) requires you to use a 90 degree/right angled USB OTG cable to wire up a DAC/Amp, but even then it's a bit of a messy cable bundle compared to every other phone that has the microUSB port on the bottom center.  That's why I just gave up and bought a Fiio X1 and use that for my music when I'm taking public transit to work.

    I am waiting for the Forza OTG Micro USB Silver cable
    Pair with: LG G3, Headstage Arrow 5P (amp/dac) with the Shure 486

    Maybe Sony Xperia could work just a tiny bit better like this? Retractable cable plus an angled OTG adapter could be less messy than a short USB cable plus a short OTG cable
    Another flavor

    I connect my Samsung Note 4 to the Teac HA-P50 using a OTG USB cable through the USB DAC "B". 
    The problem I had was the DAC is drawing power from the Note 4, i.e. the phone is charging the DAC.
    Please could you recommend a solution to stop the phone from charging the DAC? Please help.

    I have this Delock Data / Power split cable.
    - Red (Power) to batterypack
    - Black (Data) to OTG and tape the 5v pin to be sure (see red tape on pic below).
    - Black (female) to DAC/Amp.

    Thanks a lot for the informative post!
    Yeah I agree that the microUSB port location sucks.
    I'm actually using 320 kbps MP3 files and some FLAC files for now, but I just wanted to make sure that my setup would be future-proof that's all.
    BTW, how bad is double-amping? and do you recommend a cheap DAC for my setup?
  11. DanBa
    What are your impressions about the sound quality without the 5V from the phone?
  12. m-i-c-k-e-y
    What is strikingly evident was:
    - Blacker background
    - More separation, definition

    How fast does the D1 drain your phone battery?  I want to do the same thing with my Samsung S5 and my Audioengine D1.

    A list of USB OTG cables:
    A list of stock Android-powered devices reportedly interworking with compatible USB DAC:
    stock Android device > digital USB audio out >> USB DAC >> amp >> headphones
    A list of USB Audio Player PRO resources (compatible USB DAC, compatible Android devices, ...):


    According to the USB Audio Player PRO (UAPP) web site, the Audioengine D1 is a working audio device and the Samsung Galaxy S5 is a working Android device.
    Galaxy S5 using UAPP >> Ugreen microUSB OTG cable adapter + regular cable provided in the Audioengine D1 box >> Audioengine D1 USB DAC/amp >> headphones
    m-i-c-k-e-y's solution: The battery pack powers the Audioengine D1.
    Galaxy S5 using UAPP >> Ugreen microUSB OTG cable adapter + Delock Data / Power split cable ("and tape the 5v pin") powered by a 5V battery pack + regular cable provided in the Audioengine D1 box >> Audioengine D1 USB DAC/amp >> headphones

    Thanks so much!  I look forward to trying this out.  My concern is excessive battery drainage, but I'll see how it goes.  I'm probably worrying needlessly.
