Classification: CPC H  G | IPC G  H

Claim 10:
11. An ear device comprising:
a housing configured to be worn on or over a user's outer ear or in the user's ear canal;
included in the housing:
a loudspeaker;
at least one inertial sensor;
an input device; and
at least one processor;
memory storing instructions that when executed by the at least one processor, cause the at least one processor to perform operations comprising:
determining a reference attitude of the ear device based on sensor data collected by the at least one inertial sensor;
storing, in the memory, the reference attitude;
receiving, with the input device, a first user input indicating a user request for a volume control mode of the ear device;
receiving, with the at least one inertial sensor, a rotation input;
determining an amount of volume level increase or decrease based on attitude change relative to the reference attitude due to the rotation input;

adjusting a volume level of the ear device in accordance with the volume level increase or decrease, wherein the volume level increases or decreases by an incremental amount as a function of incremental angle displacement resulting from the rotation input; and
receiving second user input indicating a second user request to release the volume control mode.
