How to enable wireless listening

How to use wireless listening without the stethoscope earpiece (optional)
What is wireless listening?
Wireless listening allows you to hear real-time stethoscope audio through Bluetooth-enabled headphones, earbuds, speakers, or hearing aids.
This feature is available with all Eko devices and is designed to:
-
Increase flexibility in how you listen
-
Help maintain a safer distance from patients
-
Allow real-time audio sharing with others in the room
⚠️ Tip: For the best experience, we recommend:
High-quality Bluetooth audio devices
Connecting only one or two Bluetooth devices to your phone at a time
How to enable wireless listening
- Open the Eko app on your mobile device.
- Power on your Eko stethoscope and connect it to the Eko app.
- Pair your Bluetooth audio device (headphones, earbuds, speakers, or hearing aids) with your phone or tablet. See this article on device compatibility to ensure your audio device will work for wireless listening.
- Place the stethoscope on your patient. Audio will automatically stream to your Bluetooth-connected device.
- Adjust volume using your phone or on the Eko device.
Want to share live audio with a patient?
We recommend using a high-quality portable speaker to share live stethoscope audio in a room.
👉 Here are our recommended speaker brands
Can I use my phone speaker?
We do not recommend using your phone speaker due to poor audio quality. Phone speakers can't accurately reproduce the low-frequency heart and lung sounds needed for clinical evaluation. However, if needed:
- Connect your Eko device to the app
- Go to the Listen screen
- Tap the audio icon in the bottom-left corner
- Adjust audio filters and volume on your phone and/or stethoscope
Hearing aid users: Alternative Bluetooth connection
In addition to streaming audio through the Eko App, users with hearing aids may prefer a direct connection.
The Eko CORE 500™ has a removable earpiece that connects via a TRS jack. This allows you to:
-
Connect a Bluetooth transmitter directly to the CORE 500
-
Bypass the Eko App for a simplified audio workflow
⚠️ Please note: This setup may improve your listening experience but prevents you from using the other features of the Eko app (e.g., recording and 3-lead visualization).

Using Made for iPhone (MFi) hearing aids
If you’re using Made for iPhone (MFi) hearing aids, iOS now requires you to enable a setting in Apple Accessibility so all audio streams via Bluetooth to your hearing aids.
To enable this:
-
Open the Settings app on your iPhone.
-
Go to Accessibility → Hearing Devices.
-
Select your connected hearing aids.
-
Turn on Play System Sounds (or Play All Audio, depending on your iOS version).
This ensures stethoscope audio from the Eko App streams correctly to your hearing aids during wireless listening.
What are “Made for iPhone” hearing aids?
MFi hearing aids connect directly to your iPhone, iPad, or iPod touch without extra accessories. They stream calls, music, and app sounds straight to your hearing aids over Bluetooth.
Popular MFi brands include:
-
ReSound
-
Starkey
-
Oticon
-
Widex
-
Signia
If you use MFi hearing aids with the Eko App, make sure to turn on Play All Audio in your iPhone’s Accessibility → Hearing Devices settings. This allows the live stethoscope sounds to stream to your hearing aids.
How to use wireless listening without the stethoscope earpiece (optional)
Removing the earpiece can help reduce infection risk and maintain a safer distance from your patients when needed. Here’s how:
For CORE 500™:
- Twist the earpiece counterclockwise to unlock and remove it
For CORE™:
- Remove the tubing by unscrewing the barb or pulling it off
Then follow the instructions above on “How to enable wireless listening” … Here’s an example of what the setup could look like:
