The 27-inch double-sided chest piece stethoscope is easy to grip and move around. An acoustic seal helps keep out ambient noise. Adjust the pressure of the Littmann® Classic III™ stethoscope in plum, 5831 to hear either high- or low-frequency sounds. You can squeeze or pull apart the ear tubes to adjust the headset. The 3M Classic III™ stethoscope has soft-sealing ear tips that conform to the wearer's ears. The next-generation tubing makes this product durable and helps it retain its shape.
