Eko CORE 500™ Digital Stethoscope — 40x Amplification, Active Noise Cancellation, 3-Lead ECG, FDA-Cleared AI with Eko+, Full-Color Display, Reimbursement Eligible — Matte Black, COR503-BLK

Truly appreciated this stethoscope when I figured out how to use it and how to manually turn it off. Battery lasts a long time. It is amazing with the tinnitus ringing in my ears constantly. It has been amazing to be able to hear murmurs and subtle sounds I couldn’t before due to the ringing. I realize everyone is different when it comes to tinnitus, but it’s been a game changer for me. Great quality and although expensive, I have been super happy with my purchase.

I’ve been using the Core 500 Digital Stethoscope for a little while now, and it has definitely exceeded my expectations. The sound quality is incredibly clear—far better than my traditional stethoscope. Being able to amplify heart and lung sounds makes assessments faster and more accurate, especially in noisy environments. The digital display is simple and intuitive, and the overall build feels solid and professional. I really appreciate the ability to replay sounds; it’s a game changer when double-checking findings or discussing cases with coworkers. Battery life has held up well, and it charges quickly. If you’re looking to upgrade or want a reliable stethoscope that gives you an edge with digital features, the Core 500 is absolutely worth it. Highly recommend for EMS, nursing, and medical professionals who want the best tools possible.

Absolutely love this stethoscope. I cannot recommend it any higher! I’ve been in the medical field for 25+ years, and I’ve always had difficulty hearing with a stethoscope to discern the various lung sounds and heart murmurs. This stethoscope muffles out any environmental noise and allows me to hear with such precision, that I can hear the tiniest, faint crackle or wheeze. Every coworker that’s expressed interest in it, I’ve handed it to them told them to go use it on a patient, and they come back in awe. It is well worth the price, in buying it through Amazon you can do longer payment plans if it’s not in the budget as a solid payment. I highly recommend it. I rarely use the Eko app, but the ability to record the EKG tracing in real time is amazing.

Love my Eko and so glad I splurged and had my name engraved on it. We have a cardiologist that comes from New Orleans to Baton Rouge to see patients and he borrows it every time. Love that you can control the volume. Patients love to see and hear their heart beat and watch their rhythm. I dropped it and damaged it. The policy to replace it was very easy process!

I am a medical student with graduate-level experience in signal processing. An early academic project of mine involved work on a portable ECG device, so I have a general understanding of the core ideas and challenges that come with designing such a device. I own a KardiaMobile portable 6L EKG device and a Littmann stethoscope with a tunable diaphragm which provide great points of comparison. My overall experience with this stethoscope is quite positive. I can see it being an useful learning tool as well, saving example EKG AND PCG recordings (simultaneously!!) of heart conditions as I observe them in the clinic. The EKG feature is easy to use, and finds a signal quite quickly (even faster than my KardiaMobile device). While it finds a signal super quick, it'd be nice to have some translation of the 3 plotted leads to the standard EKG leads found on a regular hospital system-- right now it requires some user interpretation. As far as the acoustics on this stethoscope go, it's handy to have the amplification, and I could see how it might help some clinicians with mild hearing loss. The noise-cancelling feature is also handy, reducing some of the artifactual noise you pick up with stethoscopes like the standard Littmann. HOWEVER, I find that turning the noise-cancelling can sometimes help pick up some of the higher-frequency sounds (the pulmonary setting also helps with this). Also, (nitpicking here) I've noticed the diaphragm paired with the Eko signal processing seems to be a bit different than I'm used to with the Littmann, especially on the cardio setting. Higher pressure on the Littmann emphasizes the higher frequency sounds, but on the Eko, it oddly seems to emphasize the lower frequency sounds. Also, sometimes the pressure optimal for clean EKG is not optimal for listening (in some cases). So it might require a little playing around and getting used to. Also, when using the stethoscope head paired with Bluetooth instead of the wired earpiece, there's a slight delay in the connection which is noticeable but at the end of the day is probably not a big deal, and could just be my earbuds. It is still pretty cool to be able to keep the head in my bag or pocket without the earpiece in case I see something interesting I want to record (and its fairly easy to tell on the app whether the acoustic/electric signal quality is good, even without listening). Overall, it's been both super educational and fun working with this stethoscope, and I look forward to using it more!

Game-Changing Digital Stethoscope with Unmatched Clarity The Eko CORE 500™ Digital Stethoscope is hands down one of the best investments I’ve made in medical technology. As a healthcare professional, having a high-quality stethoscope is essential, and this device exceeds all expectations with its exceptional sound quality, noise cancellation, and advanced digital features. Key Features & Performance: ✅ Outstanding Sound Amplification & Noise Cancellation – The CORE 500™ delivers incredibly clear and crisp auscultation sounds, even in noisy environments. The active noise cancellation effectively filters out background noise, making it ideal for use in busy hospitals and clinics.

The ability to switch between them ensures that I can use it like a traditional stethoscope when needed or take advantage of digital amplification when working with hard-to-hear sounds. ✅ 40X Amplification – The 40X amplification is a game-changer, particularly for patients with faint heartbeats or lung sounds. It significantly enhances diagnostic accuracy, helping to detect murmurs, arrhythmias, and other subtle abnormalities. ✅ Visual Phonocardiogram Display – The built-in display provides a real-time waveform visualization of heart sounds, which is an incredible tool for both learning and clinical decision-making. It adds an extra layer of confidence when assessing cardiac conditions. ✅ Eko App Integration & AI Capabilities – The stethoscope seamlessly integrates with the Eko App, allowing for recording, storing, and sharing audio files securely. The AI-powered analysis feature is particularly helpful for screening for heart murmurs and AFib, enhancing diagnostic accuracy. ✅ Long Battery Life & USB-C Charging – The rechargeable battery lasts for multiple shifts on a single charge, and USB-C fast charging ensures it’s always ready to go. Comfort & Build Quality: The ergonomic design is comfortable to wear for long periods, and the lightweight stainless steel chest piece feels premium. The ear tips are soft and provide an excellent seal for optimal sound transmission. Final Thoughts: The Eko CORE 500™ Digital Stethoscope is an indispensable tool for any clinician, whether you're a physician, nurse, cardiologist, or medical student. Its superior sound quality, AI-powered features, and ease of use make it a must-have for anyone serious about auscultation. If you’re looking for the best digital stethoscope on the market, this is it. Highly recommended!

I've been using this as a critical care paramedic for a bit now. Overall it's a pretty good tool. It really excels with lung sounds. The different modes don't really make a huge difference, but I guess they're cool. The 3-lead ECG is a neat little toy, but it's not really useful on the job as I'll just throw the patient on the monitor. It's mostly used for showing coworkers how neat it is. I expected this though. The A-fib detection is like any other doc-in-the-box AI interpretation. It's okay, but if you can't recognize A-fib without AI, you shouldn't be interpreting rhythms. The battery life is good. I keep it off until I need to use it. For me the biggest downside of this thing is that you pay $400 for a stethoscope (I used FSA funds) and it doesn't even come with a case. You have to buy the case separately for $40. Honestly, that's ridiculous. I keep mine in an old intubation bag I had, which isn't the best, but I'm not paying $40 for a $10 case. Overall I think it works better than the other amplified stethoscopes I've used, and that's nice in a noisy ambulance. The other features are fine, but not necessary on a stethoscope in an emergency setting. It would be nice to see them make a $250 version of this with the pure electronic connection that just has the quality amplification without all the other features.
