Earbud comlink
An ear-comlink, also referred to as an earbud comlink, represented a short-distance comlink device engineered to be worn within the ear of the user. Its purpose was to enable private communication in a subtle and inconspicuous manner. Individuals such as spies, card players who cheated, and ambassadors frequently utilized this technology. Activation of communication could be customized, responding to actions like touching the ear, clenching the teeth, or moving the jaw.
In the era of the Clone Wars, the bounty hunter known as Cato Parasitti employed an ear-comlink to stay connected with her associate, Cad Bane. This occurred during their operation which took place at the Jedi Temple.
