Android phones and USB DACs
Jul 5, 2016 at 1:12 AM Post #8,222 of 9,526
Hello you very helpful bunch,
 
I have an LG G5 and the "martin" hybrid valve headphone amplifier with DAC (Kickstarter).
 
So I have sound working fine.
 
The problem is when I connect the phones USB-C to the DAC's micro-USB my phone starts charging the DAC's internal battery, I lose 1% phone battery charge for every minute the DAC is connected, not useable.
 
So, if it's possible, I need a cable that will block my phone from charging the DAC/Amp battery, can anyone please help?
 
Thanks.

Richard

I have an Android device, a USB DAC and a USB OTG cable which are reportedly compatible, but I have not been able to make it work.
Is there a trick to make it work?

I gather this is using a standard OTG cable/adapter for flashdrives?
 
What you can do is order this extension cable below.
 
http://www.ebay.com.au/itm/251477749784?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
 
Then an OTG cable from this seller and attach it to the end. (or just this otg cable alone if you're stacking)
 
http://www.ebay.com/sch/m.html?_odkw=&rmvSB=true%7Ctrue&_ssn=yourcharger&item=301556014007&_osacat=0&ssPageName=STRK%3AMEBIDX%3AIT&_from=R40&_trksid=p2046732.m570.l1313.TR0.TRC0.A0.H0.Xotg.TRS5&_nkw=otg&_sacat=0
 
That should stop your phone from charging the DAC.

Head-Fi to the rescue - after two unsuccesful attempts with cheap Android phones, I finally got something that works straight up :
 
Lenovo Tab3 A7-10 -> Onkyo HF Player -> Dragonfly Black -> Beats Solo2
 
All up, probably one of the cheapest rigs here but I like what I'm hearing and that's the main thing. A big thank you to those who've kept this thread current - its a lifesaver for those of us who cant afford flagship phones or the iPad.

Really glad to hear you have it working. I think inexpensive tablets are an excellent alternative to smartphones when the location suits. I purchased my Lenovo tablet originally for movies, during my research I read it had OTG though wasn't my main thinking. After getting my DAC working with it the tablet has gained considerable more use, an excellent addition.

Thanks again, @H20Fidelity - the only downside is that I now find myself looking at 600--ohm Beyers and cheaper planars (T50RPII 'cheap', not SH LCD-X :d) to see just what the DFB will drive at anything above very low volume on my tablet. Manufacturers clearly read Head-Fi - understandable if they want their product to sell - but I suspect that they've over-estimated the number of people who need to drive HD800s from a portable device (or perhaps I've just under-estimated that group !).

That sounds like a task for a demo store near you to test.

Sadly, I live in a one-horse town and even the horse is bored. Like many Head-Fiers, I'm now forced to buy everything online - first world problem, I know, but frustrating nonetheless. Still, when I lived in Thailand I couldnt visit Bangkok without spending money on new toys, so it might be a blessing after all.

Hi ladies and gents I need some help.
I can't remember were the info is...
My S5 is getting drained fast in my chain.
I just ordered a powered usb hub and want to power the 5V line via that.
Is there any pre made adapters about or do I have to try cutting up 2 USB Cables and practice my soldering...

Cheers for any thoughts or links

Keep smiling

For me, it was just a case of plugging the cable that came with my USB hub into the OTG adapter's female USB-A output and pluugging the Dragonfly into the other side of the USB hub - works perfectly with my laptop but I'm having issues with my Lenovo tablet (loud clicking instead of music, and from memory that's a handshaking issue). The hub WILL accept a micro USB connector as input, but I wasnt happy with intermittent dropouts and went back to the stock cable. Given how cheap many USB hubs are online (or even in thrift stores), my advice is to give it a shot - you dont have much to lose even if it doesnt work for you. FWIW, I'm ecstatic with the hub from my laptop but that's probably a topic unto itself.
