Littmann stethoscopes are considered by many to be the best in the world. Their acoustical performance, durability, light weight, and comfort are extremely well regarded in the medical community.
Typical Littmann replacement parts consist of:
Littmann also offers “Stethoscope Identification Tags” for doctors to attach their name to the headset. These are useful for hospitals and large practices, but are also great for doctors who just want their own personalized stethoscope. The kit contains both a hand-writable tag and an engraveable plate that can be sent to their engraving service.
If you are looking to buy parts for multiple stethoscopes, consider buying a “3M Littmann Stethoscope Repair Kit,” which contains many parts for current and discontinued Littmann models. It might be easier (and possibly cheaper) than buying the replacement parts separately.
