I found why I have got a trouble the mini2microUSB cable wasn't OTG   So I have to mofify mine or build one

Hello   Someone have got the schematic to make my own cable micro2mini OTG ?   Thanks guys ;-)

Thanks guys for yours replies I downloaded the trial version of UAPP I 'm gonna try

I read once all posts and I did not succed I can not use GS4 + ODAC, the sound is always going thru the speaker not the headphone   I own : a GS4 unroot, running under android 4.3 a JDS Labs O²+ODAC, modified to receive 2x9V batterries a OTG cable USB female to microUSB male a cable...

    I received my O²ODAC With my sm64 it's really great I use it with my laptop / VLC / 24-96FLAC   I modified the O²+ODAC to make it nomade with the 2x9v batteries. I have now to find the right android player to use it with my Samsung GS4 (4.3)

I am saying : It's better than nothing, 'till I got my ODAC, I hope it's gonna be better than with cmoy I mean I heard more music details I use the cmoy with a galaxy S4   I'll give you a feedback soon

I use my SM64 with a cmoy I am waiting for an ODAC I hope the difference will be there

Thanks for the feedback tom   I planned to use an arcam rpac or a microstreamer but I am not sure, I'm still thinking about it

Hello,   I also have got a SM64 and I would like to know (I'm curious ;) ) what is your setting (smartphone/dap/amp/dac/lod/otg) Can be interesting to discuss about it thanks

I did it you send them an email, to ask them to ugrade and replace your old V1 to V2 They expertise you headphone before they accept the deal in case they find a problem and it cost you $100/150 the only difference between both, it's the removable cable

Send an email to earsonic, you can have an update for 100/150€ to an exchange to a SM3V2
