The Littmann CORE provides wireless functionality utilizing Bluetooth technology. To unlock this functionality, please download the Eko App in the App Store or Google Play Store (available on both iOS and Android). Follow the steps below to use the Littmann CORE with the Eko App to wirelessly auscultate.
User Manual and Indications for use can be found here.
Step 1: Open the Eko App (available on iOS and Android) on your mobile device and turn on Play from Headphones under the Settings panel of the App.
Step 2: Make sure your preferred headphones are plugged into or paired with your phone. We recommend using wired headphones for best sound quality but have beta tested with airpods and got clear sound quality with the following iOS devices: 5s, 6, 6s, 8, X, XR, XS, XS Max, 11. We have also beta tested airpods with the following Android devices which provide clear sound quality: Pixel 3, 3XL, 2A, Galaxy Note 8, Galaxy S10+, Galaxy S8, Motorola Moto X4, LG Nexus 5X If you choose to use airpods, or other wireless headphones, we recommend testing the sound quality and having wired headphones as a backup.
Step 3: [DO NOT TRY TO DISASSEMBLE THE CORE FROM THE STETHOSCOPE]
If needed, you can tie the stethoscope together (see Image 1 for an example of how to do so) but otherwise, the stethoscope should be left as is.

Step 4: Turn on the Littmann CORE and pair to the Eko App. Once the device is paired to the Eko App, you can put your mobile device in your pocket or hold in your hand during auscultation. The App does not need to remain open during auscultation; it will still stream sounds in the background (i.e. if your phone locks).
Step 5: Put a glove / cover / stethoscope sleeve of your choice on the Littmann CORE so that the entire device is covered. This can be changed between patients and the device can also be cleaned with 70% isopropyl alcohol wipes (do not submerge device in liquid).
Examples of covers: (you can also use surgical gloves)
Step 6: Auscultation. Use the covered/protected Littmann CORE for auscultation and sounds will be streaming live through your headphones.
