              Thank you for taking the time to provide us with your feedback. In order to ensure the best heart rate accuracy, it is important that you are using the proper size and the headphones securely fit in the ear. The size 7 enhancer is pre-installed on the headphones and 3 additional sizes (5, 6, 8) are available in the box. Often times the most accurate signal is achieved by using the largest size that fits comfortably in your ears.
              Once you’ve found the right size, it’s important to ensure that the enhancers are properly installed on the ear buds so that material is fully stretched over the bud and the window for the heart rate (HR) sensor is not covered.
              More helpful tips for getting the best results:
              -Insert the earphone into your ear so that the green heart rate sensor on the LEFT ear bud is fully hidden inside the ear (behind your tragus).
              -The ear loop should not be pushed backwards to align with arc of the ear perfectly; it is likely there will be negative space between the headphone loop and your ear.
              If you’re still having issues after trying these tips, please contact us at ua.jblsupport@harman.com and the Customer Service team will be more than happy to further assist you. JBL
