Acoustic Features

Sound Quality

The Littmann 3100 Electronic Stethoscope has amazing sound quality. You can increase the amplification up to 8 times and even customize the configuration. Medics praise the steth for its sound quality that is not only clear, but also crisp.

The steth can reduce noise by about 85%. Most customers are happy to add a few dollars to switch from the traditional stethoscope to the Littmann 3100.


Changing the batteries (AA size) of the steth is not complicated. While the batteries are not rechargeable like those of other electronic stethoscopes, they last long and are easy to swap.


Considering the weight of the chest piece of other electronic scopes, the 3.45 ounces of the Littmann 3100 is a plus. The whole scope weighs 6.6 ounces, which is the same or even less than just the chest piece of some electronic steths.

Tube length

The tube is 28 inches, which is perfect for most people. However, some customers have complained of the tubes malfunctioning after some years of use. The tube is not covered under the warranty.


The Littmann 3100 stethoscope comes with a warranty of 2 years, which many people are fine with. However, some customers complained that the steths they sent for reviews were returned still having the same problem. A reviewer, for example, complained that his steth still has a problem of not turning on when it came from being reviewed.

Frequently Asked Questions

Can I use the Littmann 3100 stethoscope with a hearing aid or my cochlear implant?

If you just recently got your cochlear implant or hearing aid and have never used them with regular stethoscopes, it might be challenging learning to use them with the Littmann 3100. However, since the stethoscope has volume controls, you can remove your hearing aid and just take advantage of this.

However, if you usually wear your stethoscope with your hearing aid every day, you can continue doing so after fine tuning the sound level. Check out Audiology Online for more information about hearing aid and stethoscopes.

Should I replace my Master Cardiology or my Cardiology III steth with the Littmann 3100 model?

Most customers recommend this steth for medics with some degree of hearing loss. However, if you don’t have a hearing problem, you can still use the steths if you want. The functionality and qualities of the Cardiology III and the Master Cardiology are almost the same as those of the Littmann 3100.

Does this stethoscope have an internal memory or a sound recording feature?

No. Unfortunately, there is neither an internal memory nor a sound recording feature with this scope model.
