1. An acoustic apparatus comprising:
two first and second acoustic devices respectively worn in a left ear and a right ear of a user, wherein
each of the two acoustic devices includes:
a detection unit configured to detect a timing to transition to each of a first power-saving mode and a second power-saving mode;
a battery;
a monitoring unit configured to monitor a remaining capacity of the battery;
a signal processing unit configured to process an input sound signal;
a sound-emitting unit configured to acoustically output the processed sound signal;
a communication unit configured to transmit the processed sound signal to the communication terminal, and be connected to a communication terminal owned by the user to allow signal transmission and reception; and
a control unit configured to stop an operation of the signal processing unit based on the detection of the timing to transition to the first power-saving mode, and
the control unit is configured to
notify of prompting the user to charge a first acoustic device, which has a smaller remaining capacity of the battery, for a predetermined time and make only a second acoustic device, which has a larger remaining capacity of the battery, continued to be used based on the detection of the timing to transition to the second power-saving mode.
