Product Overview:

  • Attaches to your own stethoscope and enhances auscultation through amplification, Active Noise Cancellation, and powerful software.

  • Toggle between analog listening and loud, clear sounds amplified up to 40X for unrivaled flexibility.


Digitize the Stethoscope You Already Own

Get more from the stethoscope you already own with dual-mode acoustic and amplified listening. The new CORE Attachment enhances its powerful 40X amplification with Active Noise Cancellation—helping to reduce background noise even in noisy clinical settings. To further improve listening, we listened to our community and redesigned the CORE to be 25% smaller and 30% lighter, for more comfortable use throughout the day.

With CORE, you can toggle between traditional analog examination and loud, clear heart and lung sounds. Then visualize what you hear through waveforms streamed in real-time to a smartphone or tablet. Eko’s powerful software integrates seamlessly with the new CORE, enabling clinicians to deepen their analysis and even share exams for a second opinion. CORE is compatible with the most popular analog models and assembles in minutes to enhance auscultation.
