A wireless head set is provided to clearly hear a desired sound by improving a listening environment of person having a degraded hearing ability. A correcting part(405) corrects a gain and a dynamic range according to a frequency band in order to fit into a hearing ability. The correcting part corrects a signal of a microphone(401) according to the frequency band. The corrected signal is connected to a receiver(404) through a signal processing part(402). A wireless transceiving part(403) performs a role of wirelessly transmitting/receiving a sound signal. A communication protocol processing and compressing/expanding part(406) compresses a sound signal and a protocol related to communication. The communication protocol processing and compressing/expanding part releases the compressed sound signal. The signal processing part outputs the processed signal to the receiver by processing the sound signal. |
