I saw this mentioned in another thread about call quality, but what do you guys think about the headphone jack's sound quality - overall? I was playing some music (via google music app) into my car's stereo through the headphone jack and it seemed to sound better to me than the EVO 4G. It's hard to tell over stock car speakers though. I have yet to plugin my JH13 monitors (really high quality headphones) but I will sometime this weekend. Let me know what you think.
