When performing an EB on a pair of earbuds, you wish to put the blame on the manufacturer.
By talking about tears on the package or broken seals you make it sound like the parcel's been tampered by a thief along its way to you. Given a crime has evidently been committed, you will most certainly be asked to file a PR.
That's a totally unnecessary approach. Just tell them the earbuds were missing and that everything else was fine, no sign of tampering whatsoever. Most sellers won't bother with collecting the charging case, cables etc.
