The Phonak Open Dome 4.0 is a replacement earpiece for Phonak and Unitron receiver-in-canal hearing aids. Its open design with ventilation holes lets sound in and out naturally, which keeps the ear canal from feeling plugged. It suits people with mild hearing loss who want a bright, unoccluded sound and who accept that domes wear out and need regular replacement. Compared with closed or power domes, it gives less bass and less isolation but a more natural feel and less of the stuffed-up sensation.
