Littmann’s model 3100 and model 3200 are electronic stethoscopes which can be utilized by all clinicians. They are lightweight with comfortable earpieces and provides the user with a visual heart rate monitor. The displays of both models are backlit for low-light conditions. There is also an auto-on feature which allows the stethoscope to remain in sleep mode until used. The difference between the 3100 and 3200 is that the 3200 offers a record feature linked via Bluetooth to an additional app. It is easily downloaded from Google Play or the App Store. They are available for a variety of prices from various vendors. Both are latex-free though both also contain metal, making them incompatible with MRI.

Frequently Asked Questions

Can I connect my Bluetooth-enable hearing aid to the Littmann 3200? No, at this time, it is not compatible with any hearing aid.
Can I engrave the stethoscope? Littmann does not provide engraving. However, there are other companies that sell and engrave the electronic stethoscopes.
What is StethAssist software? StethAssist is a software program used with the 3M Littmann Electronic Stethoscope Model 3200 for the recording and display of heart sounds and other physiological acoustic signals. StethAssist software works with the Littmann model 3200 stethoscope, and runs on a PC meeting the specified requirements.


The 3M Littmann company has a lot of experience in producing electronic stethoscopes. Both of the 3100 and 3200 models will relay accurate sound to the clinician using them; utilizing state of the art technology. As with any medical device there is a learning curve. However, this is easily and quickly overcome via the accompanying video. Instructions provided by Littmann are clear and easy to understand. It should be mentioned though that neither stethoscope is operational if the batteries are dead. Each operates with one AA cell battery and the battery life is variable depending on use. The 3100 model provides excellent ability to assess lung and heart sounds and the 3200 model adds the recording feature. To purchase the extra app for this Bluetooth-enabled app, go to Google Play or the App store. For clinicians looking for a lightweight, reliable electronic stethoscope, either of these models would work well. If you need or wish to record heart/lung sounds, the 3200 model is what you should purchase.

    My Experience

    I have purchased both the 3100 and 3200 over the years. While they are lightweight and excellent quality some of the features need work.

    Pros: What did you like?

    Weight - very lightweight, works well when the battery works.

    Cons: What didn't you like?

    Neither the 3100 or 3200 works if the battery isn't charged - its just a useless piece of jewelry. Would be nice if it would at least revert back to a normal stethoscope. When the battery dies, your steth is dead too. The overall durability of the stethoscope is questionable too as I've had to replace them every 3-4 years because they just cease to work. I gave up on my 3200 when after replacing the batteries several times, it continued to turn off mid-exam. When I called Littmann they were willing to fix it but at a cost of $165. Since you can purchase a brand new stethoscope for another $100 or so, I didn't think this was worthwhile so I have gone to using another brand of electronic stethoscope. Too bad too because for >25 years I've used Littmann products and been very pleased.
