Sennheiser Momentum Sport True Wireless Earbuds

These earbuds are built for athletes who want high-quality sound and fitness data in one device. A 10 mm transducer delivers a sport-tuned profile with impactful bass. Integrated sensors track heart rate and body temperature, syncing with popular apps and sports watches. Adaptive ANC and a semi-open design let you control how much of your surroundings you hear.

Fit, pairing and daily use

Multiple silicone ear tips in three sizes and ear fins in four sizes let you dial in a secure, comfortable seal for intense movement. The IP55 rating protects against sweat and splashes. Tap controls handle playback, calls and mode changes without a phone. Bluetooth multipoint connects to two devices at once. A 10-minute quick charge adds 45 minutes of playtime when the battery runs low.

Who these suit and who should look elsewhere

Runners, gym-goers and outdoor trainers who want audio, noise control and biometric tracking in a single compact package will benefit most. Buyers who need longer continuous playtime than six hours per charge should consider alternatives. Users who prefer over-ear headphones or require wired audio input will not find those options here.

Questions about this item

How can I confirm the 10 mm transducer is delivering the sport sound profile after pairing?

Play a bass-heavy track; the earbuds should produce impactful low end without distortion, and the adaptive ANC should suppress gym noise when activated.

Which accessories are included in the box and what must I purchase separately?

The package contains the earbuds, charging case, USB-C cable, multiple silicone ear-tip sets in sizes S/M/L and ear-fin sets in sizes N/S/M/L; no extra items are required for basic operation.

Which version should I choose for 24 hour total playtime with 6 hour earbud battery life?

The single Olive model listed provides 6 hours per charge on the buds and 18.5 hours from the case for 24 hours total, plus 45 minutes of play after a 10 minute quick charge.
