Phonak Hearing Aid Domes

    • Available in three sizes for small, medium, and large ear canals, and three styles including open, closed and power. Phonak’s replacement hearing aid domes should match your canal size and type of hearing loss. Designed for Phonak receivers 4.0 (Marvel, Paradise)

      OPEN- For mild to moderate high-frequency hearing loss, open domes allow sound from the outside to pass into the ear canal. Frequencies that are not amplified in your hearing aids will be presented naturally. The open structure also allows your own voice to sound natural to you when you speak. However, they are somewhat more prone to feedback than other designs, and are not appropriate for those who require amplification of lower frequencies.

      CLOSED - Similar to open, but with much smaller openings. They allow more low frequencies to be amplified, reduce feedback, and still allow for a more “open” feeling than the “power” style. They are appropriate for those with moderate hearing loss.

      POWER - The most occlusive type of dome available, power domes are appropriate for those with moderate to profound hearing loss. They reduce feedback significantly and do a good job of reproducing low frequencies.
