Troubleshooting 101.....

Is your earpiece Bluetooth or wired? If Bluetooth, then check your settings, and re-pair the earpiece.

If not, try another ear piece. If it doesn't work, then your jack is probably bad. If it does work, your ear piece is broken.....

If the jack is bad and your phone is under warranty, get it replaced.

If by earpiece you mean the speaker on the phone that you put against your ear, many of the Treos had defective earpieces that would stop working particularly for the Treo 600 and then some of the 650s. If you do a search, you might find some information on solutions by either going back to Sprint or opening up the phone to connect loose contacts.
