The Phonak Cap Dome 4.0 is a disposable medical-grade silicone covering that protects your hearing aid from wax, moisture, and debris. Phonak 4.0 Cap domes are suitable for narrow, small, or medium size ear canals.

Phonak SDS 4.0 Cap Domes feature a new and improved build-profile which help keep the dome piece comfortable and appropriately seated in your ear canal throughout the day. Phonak Cap Domes are designed with minimal surface area and no added extensions allowing a natural listening experience without poking or irritating the ear canal wall when inserted. 

Phonak SDS 4.0 Domes effortlessly attach to Phonak Marvel, Paradise, and Kirkland RIC hearing aids. Maximize hearing aid sound quality and speech clarity by replacing domes along with Cerushield Disk Wax Filters and Phonak 4.0 Retention Locks monthly, or when your hearing aid is blocked and stops working.
