Sennheiser MOMENTUM SPORT True Wireless In‑Ear, Black

Train harder. Hear stronger.

The Sennheiser MOMENTUM SPORT isn’t just another pair of workout buds—it’s a performance tool. With in‑ear heart‑rate and body‑temperature tracking, bass‑charged Sennheiser sound, and a semi‑open acoustic design that reduces footfall and “own‑voice” thumps, these true wireless earbuds keep you locked in the zone without locking you out of your surroundings. Built to endure sweat, impact and weather, they turn every session into a smarter, more focused push toward your goals.

Why Audiophiles Choose This Product

• • Sound quality: Energetic, bass‑forward tuning that stays clean and detailed thanks to Sennheiser’s 10 mm TrueResponse dynamic driver. Reviewers highlight lively, emphatic sound that motivates without smearing the mids.
• • Engineering: Semi‑open “acoustic relief” channel vents reduce body‑borne noise (footsteps, breathing) and minimize occlusion during runs; Adaptive ANC, Transparency, and Anti‑Wind modes adapt to changing conditions.
• • Practicality: IP55‑rated earbuds and IP54 case shrug off sweat, dust and splashes; cheek‑tap control works even with gloves; secure fins and tips keep everything in place through sprints and circuits.
• • Compatibility: Broadcasts heart‑rate over the standard Bluetooth HR profile to popular apps and devices (Apple Health/Watch, Garmin, Strava, Peloton), with deep Polar Flow integration for coaching and analysis.
• • What sets it apart: It’s a rare blend of audiophile pedigree and biometric smarts—real‑time in‑ear heart rate (30–220 bpm) and body temperature (±0.3 °C) alongside aptX Adaptive Bluetooth for high‑quality, low‑latency audio.
