This portable high performance stethoscope offers efficiency in auscultation that is unprecedented in a general examination stethoscope.
Its unique "Master" chestpiece lets you monitor low and high-frequency sounds by simply alternating pressure. The 3M Littmann Master Classic II Stethoscope's chestpiece assures long-lasting performance and durability. It is protected with a hand-polished, scratch-resistant finish. A reinforced double-leaf spring and thick binaural provide extra durability, while still maintaining portability. The 3M Littmann Master Classic II stethoscope provides excellent acoustics in a portable design. The two headsets allow both the instructor and student to perform auscultation on patients simultaneously.

  • The patented tunable diaphragm alternates between low and high frequencies without turning over the chestpiece. This allows for same-site auscultation.
  • The chestpiece is finger-contoured for an easy-grip, secure hold.
  • The lightweight, adjustable-tension headset, and patented 3M Littmann Snap-tight Soft-sealing Eartips make the stethoscope even more comfortable to wear.
  • The thick single-lumen tubing provides excellent portability, allowing you to fold the stethoscope easily into your pocket without kinking or breaking.
  • The new Master chestpiece makes it easier to auscultate under a patients gown.
  • It features a nonchill rim and diaphragm assembly for patient comfort.
  • Latex free.
  • Three-year warranty.
  • Length: 40 inches.
  • Black and Burgundy Tubing only!
  • Single-sided tunable chestpiece.
  • Note: We are unable to ship Littmann Stethoscopes outside of the United States.


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

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