1. 1/5Can’t recommend unless amended.

   Was unaware my $400+ Littmann Core requires me to pay an additional $100+ a year in order to access key features like AFIB and murmur detection. Additionally, it can’t seem to detect a correct heart rate on a recording. It also refuses to play back the recording on your phones speaker, you can’t hear it without headphones. Additionally, I have trouble hearing on patients. I can hear on myself okay. But on patients? It’s like it doesn’t even work. I thought I was going crazy because I couldn’t hear anything. Mine is engraved so I can’t return it. Bummer kinda. I was so excited, and initially thought it worked well until I used it in the hospital. Maybe I need to get the hang of it or something, but the extra “subscription fee” is almost enough for me. It’s sad because I really wanted the Eko Core 500 in the future, but with companies putting everything you physically purchase behind a paywall (think, the push-to-start button on your car or heated seats both of which came with the car you paid multiple grand for, all because it’s digital and remote) I have immense reservations. There is no way to guarantee they won’t nuke the functionality of the product I purchase (and based on reviews it seems they already did). I used to want everything to go digital. Now I’m unsure. Sad.

2. 2/5It’s okay

   I originally bought the Eko Littman stethoscope during the pandemic so I could better hear patients in a noisy environment. It worked great and I believed I could hear better. Fast forward a few years, I am now a private duty home health nurse. I compared sounds with the amplifier and without the amplifier, and I much prefer listening without the amplifier. Some sounds like heart murmurs are difficult to hear through the amplifier. And diminished breath sounds are amplified to where they sound normal if you don’t know your patient. I was not impressed with the “ecg” ability. It looks nothing like an actual ecg and is only useful for visualizing arrhythmias. I’ve gotten to where I just leave the amplifier off of my stethoscope because using the stethoscope with the amplifier attached and off mutes the sound. Would also like to add that the on button is very easy to accidentally turn on and drain the battery so I usually have to keep tape on the button so it stays off.

3. 5/5Amazing!

   I never write reviews, but this stethoscope blew me away and I decided to take the time to give my honest opinion. I got the purple one and the color is amazing. When I first unboxed it and used it, there was a learning curve, the placement is slightly different (I used the core prior to upgrading to the eko) and it’s a lot lighter than the core so that took some getting used to. When I’m in the ED, it’s a little cumbersome, but I detach the chest piece and pop in my earbuds (I use Bose ultra open, I hear everything around me and can still listen to the stethoscope) and use the chest piece independently. No dirty scope around the neck! Quality is amazing, it’s Littmann. AI detection of murmurs and abnormal rhythm is getting better everyday, it’s already really good, but a trained ear is needed to verify. Overall, this stethoscope has significantly improved my cardiac and pulmonary assessments. I would recommend this product for anyone that needs amazing cardiac and pulmonary assessments! They did a great job with this one & the battery lasts forever.

4. 1/5Surprisingly unhappy with this product

   I purchased this stethoscope with some extra CME funds, and I was so excited to try it in my practice. To start with, as a pediatrician I was disappointed that they don’t have a stethoscope designed for smaller humans. That being said, I was still looking forward to trying the new stethoscope with the rhythm and murmur analysis. I tried it first on myself and it detected a fib. I repeated the exam multiple times with the same results. The following day I scheduled an appointment with the cardiologist who did an EKG which was normal. We followed that with a seven day Holter monitor, which was also normal. Ultimately this has cost over $1000 in medical bills unnecessarily. What it appears it was detecting was sinus arrhythmia. I understand that this device is not designed to be perfect but with my N of 1, it has been very imperfect. The cardiologist I saw had tried the stethoscope and was also not a fan. He stated that “it seems to present more questions than answers.” When I went to cancel my membership, the app made it impossible. When I finally got to the point where I was able to cancel I received an error message. I reached out to the support team via email and received a message that the wait times were longer than expected. I will now likely be charged for a full membership, which is ridiculous. I find it disappointing that this company has made it so difficult to cancel a membership. It seems that they want people to forget that they have a membership and leave it on auto renew. I am disappointed with the device, the customer service, and the app functionality. I would not recommend this product.

5. 5/5Great customer service

   I wrote a review with some of the shortcomings of the stethoscope/app and promptly received a response from the development team. It turns out that one shortcoming (the phone speaker audio) can’t really be fixed since it’s a speaker issue and not really an issue on the app’s part. The other one I mentioned, which was a loud noise after a recording playback finished playing through the stethoscope, was fixed very quickly. It turned out to be a known bug with some older models of the Eko Core, and I was immediately sent a replacement. The replacement was shipped without my needing to send the defective unit back first, since I would be without a stethoscope until the replacement arrived. I received the replacement unit within a few days, and I’ll now be sending back the defective unit free of charge. The audio bug seems to be gone, which is great, and it was a very easy process to fix the issue.
