Hi guys 
 
I have been going through a lot of threads trying to find out how to connect USB DAC/Amp with my android phone to listen to some good quality music and have miserably failed to find any proper solution.
 
I currently own a Sennheiser HD 380 PRO and Fiio E7K and the stupid android phone that I have been trying to connect with. 
 
Please help me guys!!!

The "stupid android phone" is the most important detail. Which model is it, what firmware does it run? Is it usb host capable?
 
Android USB audio can be a minefield.

It's a Micromax A110 with ICS android upgradeable to jelly bean and it has the usb host capability.

1.  Test of the Micromax A110 in USB host mode and a USB OTG cable adapter:
Apparently the Micromax A110 is a dual-role USB device, sometimes a USB host, sometimes a USB peripheral.

In order to interact with a USB peripheral like the FiiO E07K, the Micromax A110 should be switched to USB host mode.
It’s the case when a functional Micro-A USB plug (i.e. pin 4 connected to pin 5) is inserted into the Micro USB receptacle of the Micromax A110.
 
Such a Micro USB plug is one of the two ends of a so-called USB OTG cable adapter (i.e. functional Micro-A USB plug to Standard-A receptacle USB OTG cable adapter).

Micromax A110 >> USB OTG cable adapter >> simple USB peripheral like USB mouse or USB keyboard
 
 
2.  Test of the FiiO E07K and the USB cable:
PC or Mac > digital USB audio out >> USB cable provided by FiiO >> FiiO E07K >> headphones
 
 
3.  Test of the Micromax A110 + FiiO E07K + headphones:
Download a free trial version of the USB Audio Recorder PRO app to test the Micromax A110 with the FiiO E07K

Micromax A110 using USB Audio Recorder PRO > digital USB audio out >> USB OTG cable adapter + USB cable provided by FiiO >> FiiO E07K >> headphones
