1. An attachment apparatus for coupling to an ear of a user, the attachment apparatus comprising:
an attachment body comprising a first attachment portion and a second attachment portion, and defining an opening that is configured to enable a majority of the ear of the user to pass through the opening when coupling the attachment apparatus to the ear, wherein the first attachment portion and the second attachment portion are configured such that, when the attachment apparatus is coupled to the ear:
the first attachment portion prevents an anterior portion of the ear from passing through the opening,the first attachment portion receives, from an interaction with the anterior portion of the ear, a force that biases the first attachment portion in a direction away from a median plane of the user, andthe force received on the first attachment portion causes the second attachment portion to press against the user to form at least a portion of an acoustic seal against the user. |
