I leave beats on all the time. makes everything sound better to me, and I don't have to turn the volume up as much. when streaming though google play it doesn' t have the best sound anyways. so not like it can screw it up more.
Beats makes music sound more full when played via the speakers, but I turn it off when listening via the headphone jack. It's just an EQ setting, and is probably tuned for the speakers, other than that it's base heavy.
