Abstract
In one embodiment, earphones with bimodally fitting earbuds enable accurate reproduction of music while exposing a wearer to environmental noises on one side of the wearer. More specifically, an open earbud is designed to create a substantially open (i.e., unsealed) sound chamber around one ear while a closed earbud is designed to create a substantially closed sound chamber around the other ear. Because the open earbud is associated with sound leakage that alters both the intended level and the bass content of the music, the earphones include a signal redistribution subsystem that perspicaciously replaces at least a portion of this lost signal energy. Advantageously, such earphones expose the wearer to useful localized sounds, such as noises from an auto lane adjacent to a bike lane, while conveying the intended mix of music more accurately than conventional earphones with two open earbuds.
