The CORE 500™ is the first digital stethoscope on the market with high-definition audio, a full-color display with disease indication, and 3-lead ECG. Supported by Eko's FDA-cleared AI, the stethoscope flags abnormalities such as murmurs and AFib in seconds, right at the point of care. With advanced audio features such as amplification, noise cancellation, and fine-tuned filters, the CORE 500™ offers the ultimate audio experience for improved detection and confident clinical decision making. Some features may require an Eko+ membership.

The design of the CORE 500™ allows clinicians to rotate the stethoscope to simulate other lead perspectives, akin to Lead I, II, and III in ECG. The frequency response range is from 0.1-250 Hz. With skin contact, you see a single rhythm strip on the stethoscope display and three rhythm strips when paired with the Eko App.

The standard single-lead acquisition of the CORE 500™ is analogous to Lead II in traditional electrocardiography (ECG). Holding the stethoscope in the demonstrated orientation corresponds to Lead II.

Eko analysis software, or Eko AI, is FDA-cleared software that includes screening algorithms to assist clinicians in detecting suspected murmurs and AFib.

When the Eko App is connected and used with a compatible digital stethoscope, Eko’s FDA-cleared software automatically checks for murmurs and/or AFib. It is required to take a recording with the stethoscope or from the Eko App to receive AI results. Also, the Eko CORE 500™ Digital Stethoscope is required for AFib detection.

The Eko App summarizes any findings, including potential murmurs, AFib, or other abnormalities detected. These findings aren’t a diagnosis, but are intended to aid the clinician in reaching a diagnosis accurately, quickly, and confidently. Access to Eko AI requires an Eko+ membership.

The Eko App is included with the purchase of a stethoscope — and it's a powerful complement to the physical exam offering features such as wireless auscultation, audio filters, and PCG/ECG visualization. To unlock the CORE 500™'s full feature set, you must download the Eko App and connect your device. Some features may require an Eko+ membership.

Download the Eko App for free in the iOS App Store or Android Google Play Store. The Eko App requires iOS 15 or greater or Android 11 or greater. Full system requirements here.

Eko+ is a paid membership that unlocks unlimited access to the Eko App’s full feature set.

With an Eko+ membership, you can access the Eko App’s full suite of features including AI-powered AFib detection (CORE 500™ only) and murmur detection, and create, save, and share heart sound recordings and PDF reports.

Eko+ is offered as a monthly or annual subscription and can be purchased on ekohealth.com or through the Apple App Store or Google Play Store.

TrueSound™ is Eko’s newest audio innovation. By integrating in-ear speakers into the earbuds of the CORE 500™, the digital stethoscope can transmit the clearest, most precise sound during every physical exam.

TrueSound™ provides optimal sound filtering, background noise reduction, and minimized artifact, helping clinicians hear even the softest heart and lung sounds when auscultating.

The CORE 500™ includes an earpiece that can be securely attached to the chestpiece with a locking mechanism. The earpiece has been designed with in-ear speakers to provide clear, low frequency reproduction of body sounds. Silicone ear tips and optimized acoustic design provide increased noise reduction and enhanced sound quality.

The CORE 500™ can be used with wireless listening devices, such as hearing aids or Bluetooth headphones, connected through the Eko App. For best audio quality while using the Eko App, it’s not recommended to listen through the mobile device’s built-in speaker.

The CORE 500™ includes a 2-year warranty which is warranted against any defects in material and workmanship.

All stethoscopes purchased on the Eko website are backed by a 100% refundable, 75-day trial. We offer free returns within 75 days of receiving your stethoscope.

The CORE 500™ is a high-performance stethoscope with 3-lead ECG, designed for any clinician who needs to listen to heart and lung sounds with precision, works in settings with background noise, or regularly assesses patients for arrhythmias such as AFib. The device can be used in screening, monitoring, or triaging patients in both outpatient and inpatient settings.

Recommended for:
- Physicians
- PAs and NPs
- Nurses
- EMTs and first responders
- Respiratory therapists
- Home health providers

Yes, we encourage students to use Eko stethoscope technology to learn auscultation skills and how to identify heart, lung, and body sounds.

Eko digital stethoscope technology supports clinicians with hearing loss in several ways:

• Sound amplification helps users hear low-frequency sounds more clearly
• Waveform visualization (phonocardiograms and electrocardiograms) on the Eko App helps confirm the sounds heard and electrical signals seen
• Bluetooth compatibility allows stethoscopes to be paired with hearing aids or wireless streamers
  
  View our Stethoscope Guide for Healthcare Workers with Hearing Loss and watch a video explaining how to configure the Littmann CORE Digital Stethoscope with different types of hearing aids.

The CORE 500™ Digital Stethoscope is intended to be used by clinicians to electronically amplify, filter, and transfer body sounds and three lead electrocardiogram (ECG) waveforms. The CORE 500™ Digital Stethoscope also displays ECG waveforms and heart rate on the display and accompanying mobile application (when prescribed or used under the care of a clinician).

The data offered by the device is only significant when used in conjunction with clinician evaluation as well as consideration of other relevant patient data.

The CORE 500™ and the Eko App are cleared for use on pediatric and adult patients. Arrhythmia and murmur detection, supported by Eko AI, is cleared for use on adults 18 years and older. Some features may require an Eko+ membership.

Yes, the Eko CORE 500™ Digital Stethoscope and Eko Analysis Software are cleared by the FDA for sale in the United States.

While the CORE 500™’s clinical performance and safety is cleared for human patients, it can also be safely used on animals under the use of veterinarian professionals for animal auscultation and ECG readings. The ECG has limited functionality on animals as it can be difficult to get a signal through fur. The stethoscope and amplification should work as expected.

Note: Automated murmur and AFib detection (supported by Eko AI) are not intended to be used on animals.

Tips for ECG readings for animals:

• Wet the fur with water.
• Use ECG gel if wetting the fur doesn't help.
• Always use the CORE 500™ on the least hairy spots. Under the armpits usually works.
• Shave the hair in the area where you'll be placing the CORE 500™.

The CORE 500™ can be used safely on patients with pacemakers. However, it is not capable of recording the ECG activity of an implanted pacemaker. Refer to the CORE 500™ Instructions for Use (IFU) for cautions and warnings.

The CORE 500™ is expected to last up to 60 hours of regular clinical use on a single charge.

The CORE 500™’s observed battery life length from one full charge was 60 hours of use on average (median: 64 hours). Clinicians reported being able to see an average of 92 patients with the CORE 500™ on one full charge.

The CORE 500™ is IP44 rated, meaning it can withstand exposure to dust and splashing water. The CORE 500™ can be regularly sanitized with 70% Isopropyl Alcohol (IPA) following standard cleaning protocols. However, do not immerse the device in any liquid or subject it to any high-pressure/autoclave sterilization processes.

The CORE 500™ is FDA cleared in the United States and is for sale in the US only at this time. The CORE 500™ can only connect to the U.S. version of the Eko App, in the U.S. Apple App Store or Google Play Store.
