 Superior versatility and outstanding acoustics with two patented tunable diaphragms on stainless steel two-sided chestpiece. Headset assembly, with double lumen binaurals, is permanently set at an anatomically correct angle to minimize air leaks and prevent loosening over time. Two-tubes-in-one design reduces noise from two tubes rubbing together. Soft-Sealing eartips ensure an excellent acoustical seal in the ear canal with maximum comfort. $244.00 |  Provides the best acoustics Littmann stethoscopes offer with significant improvement in low frequency responses. With patented Littmann Special Procedure Adapter allows auscultation of difficult body parts; and pediatric, or emaciated patients. $268.00 |  Innovative design and outstanding acoustics are combined with a unique and easy to grasp Soft-Touch Chestpiece that allows easy movement between auscultation sites. Single sided stainless steel chestpiece provides both bell and diaphragm frequency responses. Latex free dual lumen tube design helps to eliminate noise artifact. $258.00 |  This stethoscope has a low profile chestpiece that fits comfortably under the cuff. Allows the user to listen selectively to low and high frequency without having to turn over the chestpiece.The Select is designed to pick up low frequency sounds, such as S3, S4 and those made by blood pressure when using light pressure. $70.00 |
 Offers efficiency in stethoscope auscultation that is unprecedented in a general examination stethoscope. The bell and diaphragm modes are incorporated into a single-sided "Master" chestpiece. No longer will you need to remove the chestpiece from the patient and mechanically switch from bell to diaphragm sides. $136.00 |  The dual-frequency, "tunable" diaphragm allows the user to listen to both low and high frequency sound by simply alternating pressure on the chestpiece. Firm pressure allows the user to hear high frequency sounds. Ease off the light "skin contact" and the diaphragm lets you hear low frequency sounds (previously heard using the traditional bell). $119.00 |  The perfect entry level and affordable choice stethoscope. The tunable diaphragm assures acoustic sensitivity and alternates between high and low frequency sounds. Special lightweight construction. $70.00 |
