Dome ThinTube & Receiver Size 7 Medium
This medium 7 mm dome is designed for compatible ReSound, Beltone and Interton hearing aids using S Receiver or HP2 Receiver systems.
Its open design allows airflow through the ear canal while providing a soft and comfortable fit around the receiver or thin tube.
Medium open dome for ventilated fittings
The dome measures approximately 7 mm at its widest point and is intended for users who need a medium-sized earpiece.
The ventilation openings help create a more open feeling in the ear and reduce acoustic sealing compared with more closed or power-style domes.
