Product Overview

The CORE 300 is our most durable, longest-lasting stethoscope, adding advanced digital audio to your exam with the option to switch to traditional listening.

  • Hear clearly, even in noisy environments: Traditional (analog) listening plus 3 digital modes (Cardiac, Pulmonary, and All-Purpose) help you hear the most subtle sounds.

  • See insights in seconds: The monochromatic display shows real-time heart rate and AI detection results directly on the stethoscope.

  • Expand your assessments: An optional pediatric diaphragm helps you treat your smallest patients.

  • Detect disease earlier: Eko AI unlocks structural murmur detection, along with sound recording, sharing, and more, with an Eko+ membership.

  • Depend on durability: Its digital battery lasts up to 120 hours, helping you power through the longest shifts, while traditional mode works without a battery.

“This scope is a perfect blend of technology and ease of use. The battery life is excellent and is able to withstand extreme winter environments while being used in pre-hospital calls. Excellent acoustic quality. Overall I love this scope.”

Julie J.

EMS Provider

“Super clear and amazing battery life. It's lightweight, yet durable. Best stethoscope yet!”

Michael C.

Physician

“Best stethoscope I’ve used! As a paramedic, the CORE 300 helps me better serve my patients through routine assessment and intubations. The sleek design is very portable and durable, from drops on the concrete to sliding around in the back of the ambulance. Even during noisy transports with lights and sirens, I'm able to hear much better than with a standard stethoscope. Battery life is also amazing. I worked ~48hrs/week and only need to charge once or twice a month. App integration is very useful in post-case review and teaching students.”

Riley D.

EMS Provider

“I'm a technology enthusiast and have tried many amplified stethoscopes over the last 10 years, and can say that the CORE 300 has amazingly crisp sound. I appreciate using it as a traditional analog stethoscope and then switching to digital mode to get a clearer sound.”

Frequently asked questions.

Who is the CORE 300 designed for?

The CORE 300 is built for routine exams in busy settings, where the priority is checking vitals and flagging major issues, even when patients are moving or partially clothed. 

It suits any clinician doing fast, everyday exams, from emergency care and EMS to ambulatory care, nursing, and pediatrics, and anyone who wants help detecting subtle acoustic signals that may otherwise be missed with analog auscultation. 

It also toggles seamlessly between digital and analog listening modes, so the exam stays familiar.

Note for veterinary professionals:
The CORE 300 is currently only recommended for human patients. Explore animal-compatible Eko stethoscopes.

What are Eko AI and Eko+, and how does the Eko App integrate them into a patient exam?

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

Access to Eko AI requires Eko+, a paid membership offered as a monthly or annual subscription that unlocks unlimited access to the Eko App’s full feature set.

When the Eko App is paired with a compatible digital stethoscope, Eko AI automatically checks for murmurs and/or AFib. To receive AI results, you must take a recording with the stethoscope or the Eko App. (The CORE 500 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. 

Can it be used with Bluetooth-enabled headphones or hearing aids?

Yes. The CORE 300 supports Bluetooth-enabled wireless listening for flexible exam workflows, so you can listen through headphones and other compatible devices. 

Hearing aid compatibility varies by model and isn't guaranteed. Check with your hearing aid manufacturer or audiologist to confirm yours will connect.

Are Eko products HSA/FSA/CME eligible? How do I get reimbursed?

Stethoscopes from Eko may be eligible for HSA, FSA, or CME purchase and/or reimbursement.
