Sennheiser Momentum Sport True Wireless Earbuds

The Sennheiser Momentum Sport are true wireless earbuds tuned for workouts, combining sport-focused sound, adaptive ANC, in-ear fitness sensors, and a secure fit with up to 24 hours of battery life.

Built to keep up with training sessions, these earbuds pair Sennheiser's sport sound profile and robust bass with adaptive noise cancellation and transparency mode so you hear what matters when you want to. Integrated Polar-powered sensors track heart rate and body temperature for on-the-go metrics, while interchangeable fins and tips deliver a locked-in fit. The compact charging case extends playback to a full day, and IP55 resistance protects against sweat and splashes.

How do these earbuds improve my workouts?

The Momentum Sport are voiced specifically for exercise: punchy lows and clear mids help music cut through ambient noise and motivate higher intensity. Adaptive ANC reduces distracting background sounds, while transparency mode lets you stay aware of surroundings during outdoor runs.

What fitness data can I track with the earbuds?

Will these earbuds stay secure during intense movement?
