The Littmann Lightweight SE model has a double-sided chest piece with a tunable diaphragm and a bell. The flat teardrop-shaped head that is designed to slip under blood pressure cuffs shows that its designers never intended it for in-depth cardiac exams.
Although the Lightweight II SE is only an ounce lighter than the Littmann Classic, that ounce can make a difference over the course of an entire shift around your neck or in a pocket. The chest piece has a double-sided head with both an adult and pediatric diaphragm.
Both diaphragms are tunable, and the pediatric diaphragm membrane can be replaced with a rubber rim to become a bell. The sound quality is significantly better than the Classic III, and overall it is a great buy.
The Cardiology IV is the best Littmann stethoscope on the market without getting into the pros and cons of electric stethoscopes. The Littmann Master Cardiology has slightly better acoustics, but at this level of performance the difference is splitting hairs. The Cardiology IV has a double sided head with both an adult and pediatric tunable diaphragm. The pediatric diaphragm membrane can be replaced with a rubber ring to become a bell if desired.
The Littmann Cardiology IV is perfect for identifying cardiac, breath, and other bodily sounds in both adults and children. It is our top Littmann stethoscope pick for its quality, versatility, and overall performance. By thickening the stainless steel head, increasing the diaphragm size, and removing the pediatric diaphragm, the Littmann Master Cardiology reaches the very peak of acoustic performance.
Although the sound quality is second to none, compromises were made in other areas that may make this stethoscope less appealing to some. If you have a pediatric rotation or see children on a regular basis, the adult-sized diaphragm is too large. It does come with a rubber pediatric attachment that still lets you use the tunable diaphragm, but it is a separate piece from the stethoscope.
Keeping track of the detachable pediatric adapter all the time could be annoying. The Master Cardiology is one of the heaviest Littmann stethoscopes because thicker stainless steel is used in the chest piece to improve acoustics. The acoustic difference between the Master Cardiology and Cardiology IV is not extreme, so the versatility of the Cardiology IV makes it a better pick for most people.
If you value acoustic quality above all else, however, this has the best sound quality before taking a large price leap into electronic stethoscopes. Electronic stethoscopes digitally boost the sound coming through the diaphragm to much higher levels and selectively decrease ambient noise.
The Littmann Electronic Stethoscope can be set to diaphragm or bell mode to selectively hear high or low frequencies respectively. Note: This review is for the stethoscope. Features common to both include: Single-piece diaphragm - Smooth surface allows for easy to cleaning, removal, and attachment. Tunable diaphragms - Both the adult and pediatric sides of the chestpiece have tunable diaphragms.

These are the ones I use at work and they are the perfect length for me. Well, I have bought and reviewed a lot of stethoscopes but they are not at home collecting dust. I do run monthly giveaways, so if you're interested and would like to join, check out my website for the giveaway of the month. They are a bit sticky to the neck and they snag and pull the little hairs at the back of your neck.
They are a bit uncomfortable, to be honest. The Littmann Classic III has a spare kit that includes: a small soft ear tip, a non-chill rim and the manual booklet. Though I love the soft ear tips that come with the Littmann stethoscopes, it still would have been great if the ear tips come in three sizes. With the Littmann Cardiology IV, the spare kit is essentially the same, the only difference is that it has an additional hard ear tip included inside.
If you prefer hard ear tips over the soft one then the Cardiology IV is for you. An extra warranty is still an extra warranty. The additional year covers the material defects that occur during the warranty period, except in the cases of obvious abuse or accidental damage.
At this point you are starting to love both stethoscopes.
