[Q] How's the audio quality through headphones? topic

I was just wondering what everyone thinks of the audio quality through headphones in terms of quality and loudness. If we had root, this wouldn't be an issue because with a few mods I could have it up to whatever I like it to be. But since there currently isn't root, how does it sound on stock? Also, is there a volume warning and does it go away until the next reboot?
