Yap. due to the poor sound card from the android and aux has poor signal. Usually adding a dsp or amp will enhance the sound pretty much. Due to this issue, I found a pretty much value ICE solution in carousel. No only installed the dsp. Bu the whole system setup at an very affordable price. Actually quit ICE cos giving up on workshop, even the award winning and reputable one cant delivered what I want unless 5 digit is spent. Can search for audioheadasia19 in carousel. Cheap and affordable for audiophile needs.
