The earhook has a dual purpose: it holds the speech processor on the ear, and it connects the battery pack (or battery pack cable) to the speech processor. The earhook can be ordered in a locking configuration to keep a child from removing it. The fit of the earhook can be customized by warming it slightly and then bending the earhook material as desired. The angled battery pack uses a special earhook that fits securely in the area between the bend of the battery pack and the processor.
