Jamming Grip For Earbud Retention

Current ear-inserts are custom made, have variable sizes, and often fall out of the user's ear. In an embodiment, a gripping ear-insert includes a sealed membrane having conformable material therein (e.g., within a cavity). The sealed membrane is configured to form a shape conforming to a section of the human ear upon insertion. The gripping ear-insert also includes a port configured to, in response to being activated, allow for adjustment of air pressure within the sealed membrane. The gripping ear-insert can also include a control coupled with the port, configured such that in response to the control being activated, the port evacuates air from a cavity of the sealed membrane, such that the sealed membrane retains its shape after evacuation of the air. As such, the gripping ear-insert is secured in the user's ear while the amount of air/air pressure is adjusted.
