1.Unique design that combines the acoustic response of a traditional bell and diaphragm into a convenient one-sided chestpiece. Bell-type low frequency response is achieved by simply holding the chestpiece in place with light pressure

2.Firm pressure will produce diaphragm-type high frequency performance A ruber gasket recessed into the chestpiece alters the diaphragm permitting the scope to achieve multi-frequency response

3.Chestpiece precisely machined to exacting tolerances from zinc alloy for outstanding performance and rugged durability. Non-chill diaphragm retaining rim for patient comfort

Large internal bore stainless steel binaurals are fixed at 15° angle for greater comfort and acoustic seal.

4.Custom molded extra thick bi-lumen 19" PVC tubing stays soft and flexible.

Tapered inner bore provides outstanding sound transmission

5.Internal binaural spring construction reduces bulk and prevents kinking when folded without producing sound clutter

6.Includes one pair of plastic eartips and two pair of PVC eartips (small and large) for the ultimate in wearing comfort and acoustic seal
