Abstract: An adjustable ear-hook earphone includes an audio earphone and a substantially auriform ear-hook connected to the earphone and configured to engage an ear of a user to hold the earphone adjacent the ear. The ear-hook has an outer portion configured to face generally away from the ear and a compressible inner portion configured to face generally toward the ear. The inner portion is compressible between a compressed position and a plurality of successive, expanded positions such that the expanded positions exert a force on the ear of the user.
