⭐⭐⭐⭐⭐ I absolutely love this stethoscope! The sound quality is incredible—heart, lung, and bowel sounds are so much clearer than with a traditional stethoscope. The noise cancellation is a game-changer, especially when working in busy facilities. The 3-lead ECG feature is a fantastic bonus, and the display is easy to read. It feels sturdy, well made, and the amethyst color is beautiful—it definitely gets compliments from coworkers! As an RN with many years of experience in hospitals, long-term care, behavioral health, and case management, I appreciate tools that make my job easier, and this one delivers. It has quickly become one of my favorite pieces of nursing equipment. If you're thinking about upgrading your stethoscope, this one is absolutely worth it. It combines technology with excellent performance and makes assessments feel easier and more confident. Highly recommend!

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.

My mother has been a nurse for over 30 years and no one has ever bought her a stethoscope. I found this out after gifting her this for her birthday. She tried it out after opening it and loved everything about it. The color is very soft but noticeable. It’s not heavy when she wears it around her neck or in her ears. She says it fits perfectly. The quality this stethoscope has is amazing.

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!

This stethoscope is amazing. The sound quality and clarity on the cardiac and wide modes are phenomenal. I don't love the pulmonary mode though because it picks up too much extra noise caused by the stethoscope rubbing up against the skin as the patient is taking big deep breaths. I've also used the app which is pretty cool. Being able to record the exam, as well as have it play on speakerphone in real time to let the patient near too, is something else. The chestpiece has a button at the top that allows you to instantly record the exam, which is saved into the app. One thing I wish they could do is to allow multiple back to back recordings. Currently, after each recording, you have to go into the app and fill in all the details (e.g., position, location) and save before being able to make another recording. The chestpiece battery duration is impressive. I noticed that when not in use, it turns off automatically to save battery. It also disconnects from bluetooth on the phone when this happens. However, once I woke up the chest piece by pressing the top button, it reconnected to my phone's bluetooth with barely any delay. It also did not have to reboot every time the chest piece was woken up. It's these little time savers that make a big difference because having to take extra steps collectively becomes time consuming. I bought the case from Eko separately. It holds the stethoscope very well. it's pretty big though. But it's a good size to fit my stethoscope as well as my otoscope. I could probably fit my blood pressure cuff in there if I wanted to. Overall great product. Patients found it interesting as well.

This is definitely an added tool that I didn't know I would be able to utilize in so many different ways. I work full-time fire and ems and this guy is top tier. Idk about the agencies you work for but we have issues with our electrodes drying out and not reading properly or those patients you get that are incredibly sweaty no matter how many times you wipe them off with a towel the electrodes just won't stick or stay on. This stethoscope has aided in both of those occurrences many times. Yes it is very pricey but I would purchase it again. The battery life is way better than I expected. Functionally all the buttons work perfectly haven't had any issues with sticking or getting gunked up. Durability is better than expected as well. Wish their were more color options.

The Eko CORE 500 is good hardware paired with an aggressively anti-consumer business model. After paying hundreds of dollars for a digital stethoscope that already captures and transmits heart sounds, Eko expects users to keep paying approximately $10 per month for the privilege of saving those sounds. Not AI interpretation. Not advanced diagnostics. Not cloud-based collaboration. Just basic recording. That is absurd. Local recording is not an ongoing service. It does not require meaningful cloud infrastructure, physician review, or continued computational expense. The device already generates the audio, the phone already receives it, and the app can already play it back. Preventing the user from saving that audio locally appears to be an artificial software restriction designed to turn a basic hardware function into recurring revenue. Eko could reasonably charge for AI analysis, automated reports, cloud storage, telemedicine integration, or enterprise features. Instead, it bundles a fundamental recording function into the same subscription and leaves customers with expensive hardware that is deliberately less useful unless they continue paying. The closed ecosystem makes this worse. The CORE 500 does not function as a normal Bluetooth microphone, Eko does not provide a consumer-accessible protocol or SDK, and there is no straightforward way to use an independent recording app. Users are therefore locked into Eko’s proprietary application and whatever pricing or feature restrictions the company chooses to impose later. This is especially frustrating for medical students, educators, and clinicians who simply want to save a murmur for later review or teaching. They may not need AI, cloud storage, patient profiles, or automated interpretation. They just want to record audio produced by a device they already own. The CORE 500 could be an outstanding clinical and educational tool. Instead, it feels like leased functionality disguised as purchased hardware. Until Eko includes unlimited local recording with the device, I cannot recommend it to anyone who expects basic ownership rights over the data their own stethoscope produces.
