Soundcore Sport X20 vs Sennheiser Momentum Sport

The Soundcore Sport X20 is the safer buy for most gym-goers: longer battery life, a tougher IP68 rating, and a much stronger owner rating. The Sennheiser Momentum Sport is the pick only if you want heart rate and body temperature tracking built into your earbuds. On sound and build, Sennheiser has the more refined tuning and a two-year warranty, but owners rate it noticeably lower and its IP55 rating is weaker for heavy sweat.

• Choose the Soundcore Sport X20 if you want all-day battery, a genuinely waterproof build, and a secure hook fit for hard training.
• Choose the Sennheiser Momentum Sport if in-ear heart rate and body temperature data matter more to you than battery life.
