Rechargeable ear-worn device with a magnetic interface

An ear-worn device system for listening comprising:

• a first ear-worn device comprising a speaker, a rechargeable battery, a first ear-worn device charging structure comprising at least two first ear-worn device electrical contacts, and an ear-worn device alignment structure comprising a magnetic material;
• and
• a charger case comprising a first case charging structure and a case alignment structure, wherein the first case charging structure comprises at least two first case electrical contacts, wherein the case alignment structure comprises a first pole-aligned bar magnet and a second pole-aligned bar magnet, and wherein the first pole-aligned bar magnet and the second pole-aligned bar magnet are opposite poles and are positioned on a first side of the case alignment structure, and wherein the magnetic material is magnetically attracted to the first pole-aligned bar magnet and the second pole-aligned bar magnet;
• and
• wherein the first ear-worn device is configured to be positioned within the charger case so that the at least two first ear-worn device electrical contacts are in electrical communication with the least two first case electrical contacts within the charger case;
• wherein the ear-worn device alignment structure is configured to retain the at least two first ear-worn device electrical contacts to the at least two first case electrical contacts within the charger case;
• and
• wherein the magnetic material does not retain its magnetism when removed from the charger case.
