My other apple earbud works fine, but my right one randomly went out, it doesn't have any breaks in the wire or anything, and I tried cleaning out the earbud. This happened to my last set of earbuds too but I didn't know how to fix it.

Hello,
See the bottom of this link for cleaning instructions for your earbuds:

Also check the charging port for lint or other debris.
In addition, see this:

Good luck.
