SDS 4.0 Open Dome


Ideal for people with mild to moderate hearing loss. Open Domes have openings to allow some natural noise to filter through to the ear canal. This allows some lower frequencies to dissipate, helping improve sound quality.

The dome should be cleaned regularly and advised to be changed every three months.

To use these domes, you should first remove the old dome by firmly grasping the speaker or tube and pulling it off. Then, take the new dome in your hand and place it in the same spot as the old one. Make sure to push the new dome firmly to ensure that it is securely attached.
