A closed dome ear cap provides a better seal in the ear canal, which can reduce feedback and amplify low-frequency sounds. However, it may also increase the occlusion effect, making the user's own voice sound louder. In contrast, an open dome ear cap allows more unamplified sound to pass through the ear canal, reducing the occlusion effect but also providing less amplification of low-frequency sounds.
