30分钟 - 2小时
Only had one ear bud (also one speaker when using accessory on car radio).
One hour had iPod apart,changed out earphone jack and battery (figured y not while I had it apart) and back together.
Plastic separaters weren't really used,small putty knife,metal AND plastic spudgers are a must. 00 Phillips screwdriver finished the job. No problem at all,FINALLY had all my music after more the a year. Thx to the step-by-step guides made it pretty easy.
