3M™ Littmann® Stethoscope Spare Parts Kit for the Master Classic™ Stethoscope contains a black rim and tunable diaphragm for chestpiece, in addition to two small (1/2 inch), black Snap Tight Soft-Sealing Eartips.

Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds press a little more to hear higher frequency sounds.

Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.
