Can earphones short circuit?
A short is caused by a break in the wire. Typically, headphones short out where the wire connects to the speakers, or, where the wire connects to the part that plugs into the headphone jack. You can usually test where the short is by wiggling the wire. Be careful not to damage the speaker itself within the casing.
How do you fix shorted out headphones?
Insert your headphones or earphones into your phone or musical device and play some music. Hold a part of the wire near the earpiece and bend or jiggle it. Make your way to the other end of the wire and jiggle every inch until you hear the headphone sound gets cut out.

What are the tip contacts for an audio jack?
With this schematic, I think that maybe the pins 2 and 3 can be shorted when the jack is inserted. What the tip contacts are used for is not determined by the component but by convention and/or the exact device you want to use.
