Tired of sharing your earphones, and have to listen to half the music. But you don't want to spend money on it either.
then this is a solution to it.
ps: I excuse myself for any spelling mistake that might occurred, English is not my native language. But please correct me if I typed something wrong, we're all here to learn.
Step 1: 1# What You'll Need
-jack plug (from the cable of old/broken/bad earphones)
-jack socket (from old electrical appliances)
-an attractive case to put everything in
-some drill bits and a drill
-a soldering iron is handy but not necessary
the first step is to extract everything you'll need from the old appliances
since this is done by your own method and preferences (from destructive to poetic) I'm not going to show how to do that.
