ABSTRACT:
An anchoring element for a device for use in the ear canal of a wearer includes a body defining a cavity for transmission of external sound through the ear canal to the wearer and having a first portion sized and constructed to fit easily within the ear canal, an inflatable bladder removably disposed about the body and adapted for inflation by air delivered into a chamber defined by the body, to cause the bladder to inflate to resiliently engage and conform to irregularities and changes of shape of the surrounding wall of the ear canal of the wearer, e.g., during chewing. The bladder inflates in a manner to seal uniformly with the ear canal wall about the device, to hold the device firmly and securely in position in the ear canal. Pressure relief means associated with the bladder provide for venting excess air of inflation from the chamber.
