An acoustic pass through is provided in telephone handsets for sounds transmitted from a hands free operation speaker laid out underneath the handset. One or more cutouts in a middle portion of the handset in various shapes such as rectangular, round, elliptical, and similar allows enhanced sound quality when the speakerphone feature is used and flexibility in handset design.
