Sony manufactures small headphone-like devices that fit directly in the entrance to your ear canal, called earbuds. These miniature headphones are often used with MP3 players and other personal audio equipment, and are less cumbersome and space-consuming than traditional headphones. If your Sony earbuds stop working, you can take them apart to examine the internal parts and try to make the repairs yourself. Sony will not honor any warranty that covers the earbuds once you open them.

Place the Flathead screwdriver in the space between the two sections of the earbud casing.
Twist the screwdriver slightly to open the space wider. Move slowly to avoid breaking the internal clips that hold the earbud casing together.
Place your thumbnail in the widened space and carefully pry the back of the earbud case away from the front with your fingers. This will expose all the internal components of the earbud.
Repeat Steps 1 through 3 for the second earbud.
