Abstract

Various embodiments are disclosed relating to sound enhancement for wireless audio devices. A technique may include determining one or more user-specific audio processing parameters, receiving an RF signal from a first wireless device, demodulating the received RF signal to obtain an audio signal, processing the audio signal based on the one or more user-specific audio processing parameters to generate a user-specific audio signal. The user-specific audio processing parameters may be based on user preferences, or may, for example be based on a user auditory profile or other information to allow a received audio signal to be processed to at least partially compensate for a user'"'"'s specific hearing impairment.
