Sennheiser Momentum Sport vs Powerbeats Pro 2

The Powerbeats Pro 2 is the better pick for most athletes. It adds heart rate monitoring, earhooks that stay put during hard training, and much longer total battery life. The Momentum Sport counters with Sennheiser's TrueResponse sound, an in-app equalizer, and swappable Open and Closed ear adapters that let you hear traffic or shut it out. Owners rate the Momentum Sport around 3.8 out of 5, so fit and app quirks come up; the Powerbeats line is widely praised for secure fit and durability.

• Choose the Sennheiser Momentum Sport if you want adjustable sound with Open and Closed ear adapters and a full equalizer for tuning your workouts.
• Choose the Apple Powerbeats Pro 2 if you want earhooks that hold through sprints, built-in heart rate tracking, and the longest battery life of the two.
