Sennheiser’s heart-tracking ANC earbuds are almost $80 off

The Sennheiser Momentum Sport Earbuds are a pretty unique piece of tech, as the noise-canceling buds feature an embedded heart rate tracker for monitoring your performance during runs and exercises. They’re also normally on the pricey side at $329.95, but right now the olive and graphite colors are discounted to a new low of $254.06 (a savings of roughly $76) at Amazon.

The Momentum Sport have a somewhat bassy tone that’s often found in fitness-focused earbuds (since that oomph-oomph can help keep you going when you’re really sweating), but they sound good and offer a secure fit for when you run. They also offer a transparency mode to keep you better attuned to your surroundings and IP55-rated weather resistance that should be able to deal with excessive sweat. But the big appeal here is you’re getting heart rate tracking without having to wear anything on your wrists, and Sennheiser doesn’t lock you into its own ecosystem as the Momentum Sport can integrate with Polar’s app for training analytics.
