• No. Tunable stethoscopes like the 3M™ Littmann® Classic II S.E. or Cardiology III Stethoscope have an attenuating ring behind the diaphragm to make the tunable function possible. The old 3M™ Littmann® Classic II/Cardiology II Stethoscope cannot be retrofitted to a 3M™ Littmann® Classic II S.E./Cardiology III Stethoscope.
