• Two patented tunable diaphragms allow for listening to both low and high-frequency sounds with either side of the chestpiece.
• Two tubes are incorporated into a single-tube design that eliminates noise artifacts created from two tubes rubbing together.
• For long lasting performance and proper fit, the headset assembly is permanently set at an anatomically correct angle. This minimizes air leaks and prevents the headset from loosening over time.
• To provide your patients with extra comfort, each chestpiece side features a nonchill rim and diaphragm assembly.
• Patented 3M Littmann Snap-tight Soft-sealing Eartips assure maximum comfort and excellent acoustic seal. An extra pair of small soft-sealing and firm eartips are provided to assure a personal fit.
• Note: tubing is measured from the top of the eartips to the bottom of the chestpiece.
• Five-year warranty.

Use
Tunable technology provides convenience, versatility and enhanced acoustics. Its dual-frequency diaphragm combines both bell (low-frequency) and diaphragm (high-frequency) modes in one chestpiece side. You control bell and diaphragm modes by pressure on the chestpiece rather than turning it over.

Bell Mode (low-frequency)
Use light contact with tunable chestpiece to hear low frequency sounds.

Diaphragm Mode (high-frequency)
Without turning the chestpiece over, use firm pressure to hear high-frequency sounds.
