Claim 11:
12. A wearable playback device comprising:
a first earbud, the first earbud comprising:
a first IEEE 802.15-compatible interface;
a first internal battery;
a first audio driver;
a housing carrying the first IEEE 802.15-compatible interface and the first internal battery, wherein the housing of the first earbud comprises:
a first portion insertable into a first ear canal, the first portion carrying the first audio driver; and
a second portion comprising:
a first magnetic interface that is configured to (i) attach a first charging adapter externally to the housing of the first earbud and (ii) align electrodes of the first charging adapter to first electrodes of the first earbud; and
a second magnetic interface that is configured to (i) attach the first earbud to a charging case and (ii) align second electrodes of the first earbud to first electrodes of the charging case; and
a first controller carried in the housing of the first earbud and configured to cause the first internal battery to charge from the first charging adapter when the first charging adapter is attached to the first magnetic interface, wherein the first internal battery draws current from one or more adapter batteries of the first charging adapter via the electrodes of the first magnetic interface and the electrodes of the first charging adapter during charging from the first charging adapter;
a second earbud, the second earbud comprising:
a second IEEE 802.15-compatible interface;
a second internal battery;
a second audio driver;
a housing carrying the second IEEE 802.15-compatible interface and the second internal battery, wherein the housing of the second earbud comprises:
a first portion insertable into a second ear canal, the first portion carrying the second audio driver; and
a second portion comprising:
a first magnetic interface that is configured to (i) attach a second charging adapter externally to the housing of the second earbud and (ii) align electrodes of the second charging adapter to first electrodes of the first earbud; and
a second magnetic interface that is configured to (i) attach the second earbud to the charging case and (ii) align second electrodes of the second earbud to second electrodes of the charging case; and
a second controller carried in the housing of the second earbud and configured to cause the second internal battery to charge from the second charging adapter when the second charging adapter is attached to the second magnetic interface, wherein the second internal battery draws current from one or more adapter batteries of the second charging adapter via the electrodes of the second magnetic interface and the electrodes of the second charging adapter during charging from the second charging adapter.
