Siemens latest new signia click sleeve domes pack of 6 pcs (Small-Vented) RunClick-CIC-Vented-Small-Pack6 Stethoscope Case  (Brown)

The click sleeves are composed of two functional regions. A fully flexible portion for maximizing canal shape adaptability, retention, and acoustic sealing. A second semi-flexible portion helps with placement in the ear canal. Given that the hearing instrument is smaller than the sleeve, different vents can be realized via holes at the tip. The vent flow is then guided through the inside of the sleeve. This completely-in-the-canal system is achieved with a non-invasive miniaturized instrument and a set of soft sleeves. By utilizing only ready-made parts, difficulties from impression taking and hard shell manufacturing are avoided. The mechanical tasks of ear canal coupling to achieve comfort, retention, and a target venting depending on the hearing loss fall on the soft earpiece alone.
