I absolutely love this stethoscope! It makes listening to breath sounds so much easier.

Nurse

I'm deaf with hearing aids, so this is a life changer! It makes my job as an EMT so much easier.

What's the difference between the 3M™ Littmann® CORE Digital Stethoscope and the Eko CORE™ Digital Attachment?

The Littmann® CORE is a 3M™ Littmann® Cardiology IV™ Stethoscope pre-assembled with the Eko CORE™ Digital Attachment.

The Eko CORE™ Digital Attachment is a Bluetooth-enabled device that attaches to and enhances a traditional stethoscope, allowing you to get more from the device you already own. It's compatible with the most popular stethoscope models from 3M™ Littmann®, ADC, WelchAllyn, MDF, and Medline with no cutting necessary.

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™ 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.

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

When connected through the Eko App, this stethoscope can be used with wireless listening devices such as Bluetooth-enabled hearing aids or headphones.

For the best audio quality, listening through your mobile device’s built-in speaker is not recommended.

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.

Use your benefits card for qualified purchases and save your order confirmation email as a receipt. You can also log in to your Eko profile to access your receipt.

If your card is declined or has an error, you can use a different payment method and contact your system administrator for reimbursement information.

If you have any issues, we recommend contacting your account administrator first. If you need to speak with us, you can contact our support team.

Eko cannot provide tax, compliance, or legal advice regarding HSA/FSA reimbursement.
