Chance are (like 99%) the Xonar DS's DAC is better then your cell phone DAC
The Xonar DS does not comes with a headphone amplifier and chances are it's line-out/headphone jack has a high impedance :(
Where as your phone should have at least a basic headphone amplifier and a much lower headphone output impedance:)
So adding an external headphone amplifier to your Xonar DS should improve the audio quality of whatever headphone your using with the Xonar DS.
The PAV2V headphone amplifier ($70) should be able to work with the Xonar DS and your cell phone.
There is also the Fiio E11 & E12, but they can't function while their battery is being recharged.
There are also cMoy headphone amps.
