i could say its quite good lah... im using this as my main rig for my audio preferences.... hook up with some good earphones...., and if u have some money to splurge u can always buy an amp and make it sound better.... battery life wise...??? 4 hours is not enuff to exhaust the batt life....
but hey... its just me... if ure think thts too much... u can always get an ipod touch...

gosh... alot of good and great earphone actually depands on ur budget, the more... the better earphone u can get....
like right now im using bijou 4 with fiio E5 amp... thinking of getting a Line-Out-Dock to fully max. my amp and my earphone to the fullest...
