Claim 1:
2. The system of claim 1, further comprising a charging case, the charging case comprising:
one or more case batteries; and
a housing carrying the one or more case batteries, the housing comprising:
a first portion forming a first volume shaped to carry the first earbud;
a first magnetic interface that is configured to (i) attach the first earbud to the charging case within the first volume and (ii) align first electrodes of the charging case to the second electrodes of the first earbud, wherein the one or more first adapter batteries of the first charging adapter and the first internal battery of the first earbud charge from (a) the one or more case batteries when the charging case is disconnected from wall power or (b) wall power when the charging case is connected to wall power, and wherein the first earbud draws current via the first electrodes of the charging case and the second electrodes of the first earbud;
a second portion forming a second volume shaped to carry the second earbud; and
a second magnetic interface that is configured to (i) attach the second earbud to the charging case within the second volume and (ii) align second electrodes of the charging case to the second electrodes of the second earbud, wherein the one or more second adapter batteries of the second charging adapter and the second internal battery of the second earbud charge from (a) the one or more case batteries when the charging case is disconnected from wall power or (b) wall power when the charging case is connected to wall power, and wherein the second earbud draws current via the second electrodes of the charging case and the second electrodes of the second earbud.
