A personal listening device 300 comprises an over-ear headphone 100 and an in-ear earpiece 200. The in-ear earpieces may be stored on or within the over-the-ear headphones. The headphone 110 and earpiece 200 are releasably connectable whereby an electrical audio input signal to the earpiece 200 forms an electrical audio input signal to the headphone 110 (see figs 4-11). The electrical audio signal may be connected either by a wired connection or a wireless connection. |
