FIT File: Are Heart Rate Earbuds The Future?

In this episode, we talk about the new Sennheiser Momentum Sport earbuds with a built-in HR sensor and our final testing of the Polar Grit X2 Pro. In addition, we dive into the differences in body temp measurements and how it can be used in workout data.

    Jabra had heartbeat in earbuds and their own app around a decade ago. Sennheiser are late to the game.
