A stethoscope is an instrument used to listen to sounds produced by the body. There are many types of stethoscopes available, and the following products show how this instrument has evolved through the years.
Stethoscope Sizes: Littmann Cardiology III
The Littmann Cardiology III stethoscope is 27 inches long (69 cm). It comes in a black color and has the two tubes in one design. The stethoscope comes with a couple of patented tunable diaphragms, one for pediatric and the other for adults.
Both can be used for listening to high and low frequency sounds. The Littmann Cardiology III design helps keep out a lot of noise. These sounds can be made when tubes come together. The pediatric section can be changed into a bell.
This is done by putting the nonchill bell sleeve in place of the diaphragm. The chest piece is stainless steel and the double-leaf binaural spring can be adjusted. The Littmann ear tips are included.
Stethoscope Sizes: Littmann Lightweight II S.E
The Littmann Lightweight II S.E. is 26 inches long. The device has a tunable diaphragm which allows you to tune in to high and low frequency sounds. The sounds can be heard by changing the pressure at the chest piece.
The Littmann Lightweight II S.E. has single-lumen tubing and comes with soft ear tips. The stethoscope is designed for LPN, nursing students and individuals who have difficulties hearing with other stethoscopes. While the model has a light weight, it is also durable. This makes it ideal for regular use.
Stethoscope Sizes: Littmann Master Classic II
The Littmann Master Classic II is 27 inches long and comes in a black color. It has the company’s unique single-sided diaphragm design and the comfortable ear tips.
The Littmann Master Classic II is made for general examination. The patented diaphragm lets you listen to low and high sounds even if you do not turn the chest piece over. The stethoscope has superior single lumen tubing.
The unit also has nonchill rim. The design makes it easy on the ears. The unit also blocks outside noise, so you can hear the sounds clearly, and it does not feel cold when pressed on the skin.

The stethoscope sizes are more or less the same. Where the products differ is in the sound they can pick up and how comfortable they are to wear. Before buying, you should read some reviews to get an idea of what is a good buy.
