3M Littmann CORE Digital Stethoscope, Our Most Advanced Stethoscope Yet, Up To 40x Amplification, Active Noise Cancellation, In-App Sound Wave Visualization, High Polish Copper Chestpiece, 8870 | Our Most Advanced Stethoscope Yet, Up To 40x Amplification*, Active Noise Cancellation, In-App Sound Wave Visualization

I love the stethoscope, particularly in cardiology since it’s so accurate and you can amplify the sound. You’re able to pick up the slightest deviation in normal sounds. It works as a normal telescope if you run out of battery. It is very soft and comfortable. I clean mine every day so it doesn’t get sticky. It is an incredible investment. I highly recommended. The size is exactly the same as a regular stethoscope and fits in any stethoscope holder.

Wife is a nurse. She and everyone else she works with love this!

Impressed with the quality of sound and how long it will go between charging

Well made, easy to use, and clear. My old cardiology stethoscope was hard to hear at times and about 8 years old. When I switched to critical care and pulmonology this stethoscope made it easy to hear everything. Battery life lasts about 2-3 weeks between charges which is good.

Very comfortable to use around your neck, if you have to. Easy to set up app.

I have always used Littmann stethoscopes since beginning my career as a physician. As I have gotten older I have felt that I struggle to hear subtle murmurs etc. The CORE digital attachment is fantastic! I can hear faint murmurs I probably would have otherwise missed. There are several things that I don't like. 1. As a physician who takes care of adult patients only, having a pediatric sized diaphragm is really not useful. This is made even more evident when you consider that the diaphragms tend to swivel very easily. I have found myself frequently having to tap the diaphragm to make sure I have the correct size selected. There is a very small dot on the tubing that I suppose is to help you know which diaphragm you have selected. The problem with the dot, is 1. it is black and blends in with the tubing. 2. When you choose the adult diaphragm, it is almost impossible to see. 2. It would be great if there were several options to choose from with regards to the diaphragm. An adult only, a pediatric only and both. That way physicians, NPs etc. could choose the chest piece that is ideal for the patients they see. 3. I was very disappointed with the sound quality using the app and Apple AirPods Pro. I was hoping to be able to use the CORE attachment when I had to see patients who were in isolation, but the sound quality was very faint. Maybe I didn't have the volume adjusted properly, that is something I will try with different volume settings and see if it makes a difference. 4. The app is ok. I find that it is very cumbersome to try to use the app to record heart sounds. You have get your phone out and open the app, then make sure that the app is connected to the CORE and then you listen to the patient. As busy as most physicians and other care givers are these days, it seems to be something that could be so much better. I can see this being very helpful in an academic setting, where a teaching attending has his medical students or residents listen to a patient while the attending records the sounds on the app. But for the vast majority of users I feel its more of hassle to try and use the app. 5. I have noticed that if you were to leave the CORE on, it will quickly drain the battery. I haven't had an issue with not having enough battery because I turn off the CORE as soon as I am done examining the patient, but it is something to be aware of. All in all, it is great and makes a difference to be able to pick up faint subtle murmurs etc. I would love to give it 5 stars, but it has enough quirks that I couldn't give it 5 stars. Hopefully it will improve with suggestions given by everyday users.

I upgraded from a Cardiology IV. I have trouble hearing in the back of a truck and this solves my problem. Works very very well. I have not tried the app for it. It also works as a regular stethoscope if the battery dies which is great. My battery hasn't died on me. Where this thing REALLY does well is lung auscultation. Was able to confirm BIAB placement very quickly on a code with all sorts of background noise happening. I downloaded the app and tried it and agree the app is not very useful, but I don't think that warrants giving the stethoscope a bad review. If you have hearing damage or work in a loud environment the scope is awesome as a stand alone like any other stethoscope in the history of medicine, the app should be reviewed separately.

Perfect for heard of hearing nurse.

Excellent quality product! Definitely recommend.

Not worth the money
