The open-fit ear domes are designed for mild to moderate hearing loss. They provide comfortable fatigue-free wearing without the "occlusion effect". Unlike closed-tip ear domes, the user will not perceive "hollow" or "booming" echo-like sounds of his/her own voice. The open-fit vents keep the ear canal open so that vibrations are not reflected back towards the eardrum.

They provide a more natural sound but may cause feedback (whistling) at high amplification volume settings. Please choose between small, medium/regular, or large sizes. Each pack includes 6 ear domes.

• Small: 6 mm (diameter)
• Regular: 9 mm (diameter) - fits most people
• Large: 12 mm (diameter)

To ensure your hearing aids' optimal performance, we recommended replacing ear domes every 3 months or whenever:

• Ear domes are damaged
• Ear domes become stiff or discolored
• Ear domes do not fit well
• You experience an increase in whistling
