Littmann Cardiology IV: The Features

Littmann Cardiology IVIf you’re looking for a better-than-the-standard or cardiology-grade stethoscope, this one deserves serious consideration. It gives the Littmann Master Cardiology a serious run for its money. This is the next generation stethoscope that has earned high recognition amongst health professionals, and stands out for it’s superior acoustic quality.
The Littmann Cardiology IV range is made in the U.S.A. and has a long-term free-repair and replacement warranty. The craftsmanship is second to none.


Acoustics Features

The new chestpiece design incorporates a tunable diaphragm on each side, one adult and the other pediatric.  The single double-lumen tube carries sound directly to each ear piece, eliminating the need for the traditional double tubes which caused rubbing noise on movement. This allows for an acoustic sound that is more clear and crisp than other models. The Littmann Cardiology IV vs Master Cardiology are getting close. Littmann will need to revamp the Master Cardiology soon as this one catching up to it.



At a total weight of 6.2 ounces, the Littmann Cardiology 4 is lighter in comparison to other Littmann Cardiology stethoscopes. With ths new release Littmann have managed to reduce the overall weight while incorporating huge enhancements.



Littmann Cardiology 4 StethoscopeThis Littmann stethoscope comes with a seven year warranty. Although it does come with some extra parts such as ear pieces, you can pick up Littmann Cardiology IV parts just like other Littmanns. With simple maintenance, the chances of needing to order replacement parts are slim. Of course you can also have the Littmann Technical Assistance assist you if need be.



As common with Littmann, this does come with an extra pair of ear tips. While most users favor the soft sealing ear tips, you can switch them with other styles if you prefer. The tubes on this model come in 22 and 27 inch lengths.  Traditionally, longer tubes were associated with reduced sound quality, but we would argue that in this case the sound-quality of this Cardiology IV model is so high, it makes negligible difference. The next generation latex-free tubing material lasts longer due to its improved resistance to alcohol and skin oils. The headpiece coating comes in Black, Smoke, or Stainless steel finishes. 

Replacement Parts

After a few years the peripheral parts of your stethoscope will start to wear and affect auscultation quality. While the actual stethoscope is still in top condition and will last generations, it’s advised to change parts every 5 years at least. Tiny dents and imperfections on the diaphragms and rubber bands will cause noise artefact and affect the air-tight seal that transmits sound. Changing parts is easy to do at home and the parts are widely available here.
