An earphone (16) for use with portable communication devices (PCDs), particularly cellular phones (20), where the electromagnetic (EM) radiation of the device is distanced from the head of the user, while acoustic waves are collected and brought through an acoustic tube (14) to the ear of the user. The earphone may employ a coupler where the coupler contains a microphone and speaker acoustically insulated from each other. The coupler is positioned distant from both the ear of the user and the PCD. The coupler delivers acoustic waves to an acoustic tube for transmittal to the ear.
