Sound attenuation devices are provided that may be temporarily worn in a person's ear. The devices generally include a first flange that is configured to be disposed in a person's ear; a second flange that is positioned proximate to the first flange and is also configured to be disposed in the person's ear (with the second flange having a proximate end that exhibits an oblong perimeter); and a cylindrical shaft extending from an interior portion of the second flange. The shaft includes an integrally connected pull tab; it extends beyond the proximate end of the second flange; and the shaft includes an integrally formed reinforcing member that spans an exterior side of the shaft and at least a portion of the pull tab. The devices further include a sound filter disposed within an internal cavity of the shaft.

The application discloses an eartip, an earphone device, an earphone housing and a hearbud housing device. The eartip can include an outer portion, an inner portion, and an encapsulated volume formed by the inner and outer portion, wherein the outer portion is designed to contact the ear canal, and wherein the inner portion is designed to fit upon a stent. In an alternative embodiment, the airtip can include an inverted body, wherein when the inverted body is at least partially folded on itself the inverted body is arranged to include a bulbous region sized for insertion in an ear canal, a cavity internal to the bulbous region that holds a gas, where increasing pressure on the bulbous region releases a portion of the gas.

An aural iris includes a lumen and an actuator coupled on or in or to the lumen for at least partially attenuating sound traversing through the lumen by selectively actuating the actuator on and off. Other embodiments are disclosed.
