Accessories & Parts

The 3M Littmann Master Cardiology Stethoscope comes with the following parts:

  • Diaphragm
  • Ear Tubes
  • Tubing

Here, we will give you a better idea of what each of these parts offers and why they make the 3M Littmann Master Cardiology such an outstanding stethoscope.

  • Diaphragm

The tunable diaphragm technology of the Master Cardiology stethoscope from Littmann is exceptional. You will find this technology on other 3M Littmann models, with only one side with a diaphragm that provides a much cleaner & noise-free sound quality.

It also catches higher, and low frequency sounds more easily and reduces overall sound-transportation time.

  • Eartubes

The headset or eartubes of the stethoscope squeeze both earpieces together with a snap-tight system for superb tightness. Boasting soft-sealing eartips with rubber build, it provides exceptional comfort despite its tight design.

Nonetheless, the right seal of the earpieces and the tubes increase overall sound quality, for less noise and interruptions.

  • Tubing

The next-generation tubing quality of the Master Cardiology provides superior flexibility, durability, and readiness for sudden operation.

Its dual-lumen build offers the perfect resistance to folding, oil, alcohol and more while keeping sound to the highest quality possible. It also prevents stains and comes in a black color that fits with any clothes.

Key Features

  • High Acoustic Performance

The first-rate acoustic performance this stethoscope achieves provides a very reliable sound quality any practitioner can get.

With a tunable diaphragm design, switching between high and low frequencies is easy, which also makes the sound quality perfect depending on the operation.

  • Reduced Interference and Noise

The tubing build of the stethoscope boasts a dual-lumen design, which in contrast with a single lumen, it is capable of reducing noises and interference in the sound.

This augments overall quality of the device and promotes a much more reliable sound delivery.

  • Versatile Operation

Despite being mostly recommended for cardiology and general operation, the device also comes with a special-procedure adaptor that works perfectly for pediatric use.

Whether it is infant auscultation or other versatility-demanding operation, the adaptor promotes better results for different applications.

  • Comfortable & Easy to Use

Being only 22 or 27 inches long and delivering a very stiff and heavy build – it comes with the perfect features for a convenient application. Boasting a hand-crafted design, it is ideal for those who look for the right product in every aspect possible.

The snap-tight ear tubes with rubber earpieces comprise a perfectly comfortable design for any user.


It is critical to mention in this Littmann Master Cardiology review, that the dual-lumen tubing alongside the tunable diaphragm increase overall sound quality exponentially, perfect for demanding users.

It picks low, and high frequency sounds without issue, and delivers the cleaner sound without effort, free of noises or interference. And of course, it does it all without harming the user’s ear or becoming uncomfortable after wearing for some time.
