JBL Endurance Peak 3 vs Sennheiser Momentum Sport

The Sennheiser Momentum Sport is the better pick for data-driven training: it adds heart rate and body temperature sensors, Polar integration and adaptive ANC, which the Endurance Peak 3 lacks. The JBL Endurance Peak 3 wins on endurance and ruggedness, with a 50-hour total battery figure and an IP68 rating against IP55. Owners are split on both. JBL buyers praise the ear-hook fit and battery but report muddy sound, call mic problems and discomfort on long wear. Sennheiser's rating is lower, so expect to weigh its biometric features against a smaller battery and a fit that suits fewer ears.

• Choose the JBL Endurance Peak 3 if you want the longest battery life and the toughest dust and water protection for hard outdoor training.
• Choose the Sennheiser Momentum Sport if heart rate, body temperature and Polar or Strava training data matter more to you than battery life.
