All of my music is on Spotify, and I use their "Extreme quality" download option which is 320kbps. Man, it sounds HORRIBLE!
I'm going to try a headphone amp this weekend because this is ridiculous. I tried out the same song my my Samsung Galaxy S2 i9100 yesterday and it sounded crystal clear!
Is it just me or is the audio quality abysmal out of the Nexus 5's 3.5mm headphone jack? With my ATH-m50x it sounds like someone is making popcorn in the background of every song I play. The crackling is so intense that it ruins a lot of my tracks. One of the best examples I can find is Lamb of God - Black Label. If anyone can try this song out on Google Music or Spotify on their phone and let me know if it sounds abysmal as well I would highly appreciate it.
