CORE 500™ earpiece

Who is this for?

✓ Enterprise institutions with a subscription to the SENSORA™ platform

If you're a customer who purchased your own Eko device, go to the Eko Help Center.

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™ has a 3.5mm audio jack that can be used with either the included earpiece or any wired audio device with a standard 3.5mm plug. We recommend using the provided earpiece with the CORE 500™ for best audio quality.

The CORE 500™ can also 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 in-built speaker.


If using other headphones, insertable earbuds provide the best sound quality.

  1. Plug the earpiece into the CORE 500™. The mark on the CORE 500™ socket should align with the right-side mark on the earpiece plug.

Detach earpiece
