An in-ear monitor (100) is provided that combines a pair of diaphragm drivers (109, 110) and a single armature driver (107) within a single earpiece (100), thereby taking advantage of the capabilities of both types of driver. Preferably, the diaphragms (109, 110) are use to reproduce the lower frequencies while the higher frequencies are accurately reproduced by the armature driver (107). Such a hybrid design offers improved fidelity across the desired frequency spectrum and does so at a reduced cost in comparison to multiple armature designs. In addition to the three drivers, the disclosed in-ear monitor (100) includes means for splitting the incoming signal into separat inputs (105) for each driver. Typically this function is performed by a passive crossover circuit although an active crossover circuit can also be used. In at least one embodiment, acoustic dampers (411, 413) are interposed between one or more driver outputs and the eartip (111).
