Littmann’s stethoscope

This unit is one of the most revered Littmann’s stethoscopes. When you ask around for recommendation, your colleagues will definitely advise you to obtain a Littmann scope.

The brand has become a popular choice among medical professionals. It’s simply because it offers excellent acoustical performance allowing the user to listen to various body sounds. It may be a simple listening device but it’s a powerful diagnostic tool that can help in assessing the patient’s medical condition.

Littmann is known for its tunable technology. It’s an innovative design with unsurpassed performance that makes it easier to listen to low and high-frequency sounds. With it, there’s no need for you to turn the chest piece over just to hear the sounds clearly.

The bell mode is for low-frequency sound and it can be activated by simply resting the piece lightly on your patient.

The diaphragm mode is used to listen for high-frequency sounds. Unlike the bell mode, you’ll need to apply firm pressure to activate it. Through firm pressure, the membrane blocks low-frequency sound so you can hear high-frequency sounds.


Because of its excellent auscultation ability, many medical professionals depend on it. Despite their individual needs, they opt for the features of this scope because of its overall quality.

Here are the best features of this unit that make it a popular choice:

  • Tunable diaphragm that’s responsive. It allows you to capture either high or low-frequency sounds.
  • Chest piece made by Littmann. As previously mentioned, Littmann is known for its excellent acoustic performance through its patented chest piece.
  • Handy adapter. It is included in the package that provides this unit greater level of versatility. This allows you to use it for infant or pediatric patients.
  • Dual lumen. It eliminates noise interference when two tubes rub together.
  • Anatomically designed headset. This is one of the best features of this unit as it won’t fall off when you’re using it. It also improves your listening ability as it meets perfectly to your ear canal.

No matter how reliable this unit is, you still have to maintain it by thoroughly cleaning it routinely. This is to ensure that the features will stay long and the overall scope’s life is extended. Cleaning it on a regular basis will also leave the unit look shinier, as if it’s a new scope.


Here are some of the reasons this unit is a great option for your medical profession.

  • Excellent acoustic performance. It’s made by Littmann; ergo, you can expect it to provide you with superb performance. Thanks for its specially designed chest piece.
  • Quickly capture both high and low-frequency sounds. You can do so by changing the pressure applied on the tunable diaphragm.
  • Eliminates noise interference. Noise interference usually happens when you’re using a scope with two external tubes. But because this unit uses dual lumen design, you won’t experience such problem.
  • Delivers body sounds accurately. Because the headset is anatomically angled to the path of your ear canal, you can hear clearly.
  • Flexible tubing. It folds tightly but the tubes won’t break making it more portable during a hectic setting.
  • Good acoustic seal. The soft-sealing ear tips of this unit can create better sounds so you can hear them regardless of the environment you’re in.
  • Comfortable non-chill diaphragm. It’s not unique in this unit because most of the latest models have this type of feature.


  • Price. This isn’t a cheap unit that you can have. In fact, it’s one of the most expensive units on the market that only a few medical professionals can afford. Nonetheless, it’s a worthwhile investment considering its many features and benefits. It can last for many years and it can help you hear clearly.
  • Some buyers of this unit complained of it having factory defect. But it only happens when you purchase it from unreliable supplier. Thus, before you buy it on Amazon, for instance, you must evaluate the seller’s ratings first. Make sure that you read the negative reviews of other verified buyers before making a final purchase.

The heart tones, for instance, can be heard better using this scope. Thus, for many of its customers, this unit is worth the investment.

They also like the idea of not having to turn the bell or diaphragm just to listen to murmurs and other sounds. With that in mind, auscultating body sounds becomes a breeze using it.

The clarity of body sounds is excellent. Many of them are blown away and sworn that they’ll never go back to using another stethoscope.


3M Littmann Master Cardiology Stethoscope isn’t a cheap unit. On Amazon, you can buy it from $191; depending on the seller. But, as mentioned earlier, it’s worth every penny because of its many useful features. It makes your job a lot easier.

It’s true that you can purchase a cheaper unit. But are you sure of its quality? Does it offer the same auscultation ability as this unit offers? Bear in mind that hearing body sounds properly can help you better diagnose your patient. If you can’t hear clearly, you can’t assess your patients and make a proper diagnosis.

With this unit, you’re paying more to have more. For your money, this unit offers highest quality for the right price. It hangs comfortably on your neck so you won’t have a problem when you use it for an extended period of time.
