More Information

• Other information:
  - Chestpiece:
  Equipped with a full rotational dual-output acoustic valve stem, all components are individually machined and precisely assembled. Strict tolerance control and valve mechanism ensure smooth valve rotation and accurate acoustic transmission. It enables users to switch between adult and pediatric-sided diaphragms/bells with ease and interchange both side of the chestpiece with adult and pediatric fittings (2 diaphragms and 3 bells)
  - Headset:
  Adjustable chrome-plated wide brass tubes are outfitted with enclosed flexible spring designed for a long lasting anatomical fit
  - Acoustic Tubing:
  The 2-in-1 tubes in the X-configuration, intersecting into one tube in the waist, has dual opening to adopt the chestpiece and headset provide superior acoustic quality. This high performance heavy-walled 2-in-1 acoustic tube maintains two uninterrupted sound transmission channels that further diminishes extraneous sounds in high-noise conditions and caused by the rubbing of the acoustic tubes. Tubes are constructed of non-cracking, non-sticking high-density latex-free PVC
