Is anyone else noticing sub par sound quality when plugged into either a pair of headphones or the audio in in your car? The normal speaker seems to be ok but that's kind of expected to not be the greatest. However I feel like the onboard speaker actually sounds better then when I have it plugged into my car or headhpones and I know that's not right. I upgraded from the bionic to the D4 and did not have these quality issues with the bionic. Any thoughts or suggestions? Thanks!!!
