Overview
Eko designed this digital stethoscope to amplify and filter heart, lung and body sounds while capturing an ECG through the same device. A screen on the stethoscope shows heart rate and ECG data, and the Eko app adds waveform views, recording, playback and sharing.
Amplified listening, ECG and on-device readouts in one instrument mean fewer tools on the exam cart, and recordings can be replayed or shared from the app. AI murmur and AFib detection need an Eko+ membership after the trial, and the listing gives no battery life or charging details.
Who it's for
Clinicians in noisy wards or clinics, and those who document or teach from recorded exams, get the most from it. Students or caregivers who only need basic listening and do not want an app account should stay with an acoustic model.
Pros and cons
- Amplification for faint heart and lung sounds
- Background noise reduction
- ECG with on-screen readout
- Cardio, pulmonary and wide filter modes
- AI detection needs an ongoing Eko+ membership
- Battery life not listed
- Runs on a battery, unlike acoustic models
- Waveform views require the Eko app
Performance notes
Matching the filter to the exam, cardio for the heart, pulmonary for the lungs and wide for general body sounds, governs what the amplifier brings forward. Noise reduction trims ambient sound so faint sounds can be raised without the room drowning them out. Murmur and AFib flags depend on an active Eko+ membership and the app connection.

Frequently asked questions
Does the Eko CORE 500 detect murmurs without a membership?
No. Murmur and AFib detection come with the 14-day Eko+ trial and then require a yearly Eko+ membership. Basic app features stay available without it.
Can I record and replay exams with the Eko CORE 500?
Yes, through the Eko App, with single sound recording and real-time playback during exams. Unlimited recording is part of Eko+.
Is the Eko CORE 500 a standalone ECG machine?
No. It is a stethoscope with a 3-lead ECG built in, showing heart rate and ECG data on its own screen alongside amplified sound.
