Phonak Hearing Aid Domes 4.0

Phonak Hearing Aid Domes What's in the box ✓ 2 packs of 10 domes — 20 domes total ✓ Available in Open, Vented, and Power Double Dome styles ✓ Compatible with Phonak 4.0, 5.0, and 6.0 receivers ✓ Fits Audéo Marvel, Paradise, Lumity, Life, Infinio, and Audéo Sphere Infinio Dome styles Open Available in 6 mm, 8 mm, and 10 mm Open domes allow natural sound from your environment to pass into the ear canal alongside amplified sound. Your own voice sounds natural when you speak, and unamplified low frequencies come through as-is. Best suited for mild to moderate high-frequency hearing loss where low-frequency hearing is near-normal. More prone to feedback and not appropriate for those who need bass amplification. Vented Available in 8 mm, 9 mm, and 11 mm Vented domes offer a more enclosed fit than open domes while still allowing some airflow through a small vent. This design supports better amplification of lower frequencies and reduces feedback — a good fit for moderate hearing loss where some occlusion is needed but full sealing is not. Power Double Dome Available in 9 mm and 11 mm The most occlusive dome available. The double dome design creates a secure seal in the ear canal, significantly reducing feedback while delivering strong low-frequency amplification. Recommended for moderate to severe hearing loss where maximum amplification is required across all frequencies.
