I use my smartphone for all of my mobile music listening needs, which is quite a bit. Anytime I drive anywhere, go for a walk, get groceries, go the the gym etc I use my smartphone to listen to music. I've had a Htc Evo 4G, Htc Evo 3D, Samsung Galaxy Note LTE and now the Nexus 4 and the audio quality and volume on the Nexus 4 is easily the worst one. I love the phone in general but I can't seem to get the audio to sound good. I use the headphone jack and plug right into my Scion xB which has a decent Pioneer system built in and even with PowerAmp it sounds mediocre. With my earbuds it sounds better, but still not nearly as good as the Note. I had already planned to get a Note 2 before the Nexus 4 was announced and I may end up doing that and use two devices, meaning the Note 2 will be just a wifi device and I'll use it for music. I'm hoping they put out a 64GB version internationally so I can snag one. Either way, does anyone else feel this way about the audio quality?
