In this Littmann Neonatal stethoscope review, we go through the features and performance of this infant stethoscope.

Since infants are delicate beings, it is important to use the best stethoscope for examining them. The Littmann Classic II Infant Stethoscope is specially designed for infants. However, it can also be used on small pets by vets.

Features of the Littmann Infant Stethoscope

The Classic II Infant Stethoscope is probably one of the names you will often come across when shopping for a child stethoscope. With its double-sided chest piece (a small tunable diaphragm on one end and an open bell on the other), this ultra-small medical device will surprise you with its excellent performance. The newborn stethoscope is made of next generation materials instead of the natural rubber used in making most steths. Thus, it is ideal for patients who are latex sensitive.


Double -sided Chest Piece

The sound quality of the neonatal Littmann stethoscope is superb. In particular, the chest piece can hone.

However, there are concerns however about listening to lung sounds. Sometimes, lung sounds can get mixed with bowel and heart sounds. These challenges are not usually experienced with the pediatric or the normal stethoscope. The mixing up of the sounds can be due to the infant stethoscope’s small diaphragm diameter.

The bell on one side of the chest piece enables hearing of timid bowel, heart and breathing sounds of little babes.

Ear Tips

The three ear tips found in Littmann stethoscopes are also available in the child stethoscope. One of the pieces has a soft rubber tip finish that is perfect for blocking out background noise. This is useful since infants are easily startled and are prone to crying.


The newborn stethoscope is considerably lighter than other acoustic scopes. With a weight of 3.4 ounces, carrying this stethoscope around the neck shouldn’t be a task even during long shifts.

Tube Length

With a tube measuring 28 inches, the NICU stethoscope is perfect for most physiques. You shouldn’t worry about back pain since you won’t be bending over too much.


According to Amazon reviews, not many people complained about the tubes needing replacement. However, should your tubes get scuffed and scratched, you can get them replaced under Littmann’s 3-year warranty.

What is the difference between the pediatric stethoscope and the Littmann neonatal stethoscope?

The major difference between the Littmann infant stethoscope and the Littmann pediatric stethoscope is the size (diameter) of the diaphragm. The 2.7cm size of the infant steth is considerably smaller than that of the pediatric steth, which has 3.3cm. Medics love this feature and attributed the better listening experience while using the infant stethoscope to it.

What are the dimensions of the chest piece?

The chest piece of the Littman neonatal stethoscope is two-sided. One side has a bell while the other has a diaphragm. The diaphragm’s diameter is 2.7cm. The total weight of the chest piece is 1.5 ounces, which makes the steth perfect for use on junior patients.

Are there varieties of colors to choose from?

The chest piece comes in two styles; a rainbow and a mechanized stainless steel. Most buyers prefer the rainbow style.. There was also a lilac color option but it is no longer available. The NICU stethoscope colors available are Caribbean blue, peach, orange, royal blue, red, raspberry and black colors.

Can I use this stethoscope on small pets?

Yes. Many vets use the steth on small pets due to its small chest piece size. Ordinary vet stethoscopes have heads that are too big for small animals like finches, dragon bearded and the Canaries. The baby stethoscope is perfect for these small pets.

Should I Purchase the Littmann Neonatal Stethoscope?

With its attractive features, this stethoscope is perfect for little beings. If you work with infants or preemies or are a small animal’s vet doctor, this stethoscope will be perfect for you.
