Key Features:
Your workout, your sound
Tailor your sound experience for the level of immersion or awareness you prefer. Our unique Adaptable Acoustic feature offers the choice of either Open or Closed ear adapters, that match with special EQ modes to provide the perfect setting for your exercise. Choose an Open ear adapter style to stay aware of your surroundings but at the same time minimize body-borne noise, like hearing your own breathing or footsteps. Or simply switch to an insulating Closed ear adapter that blocks outside sound for an immersive audio experience.
Sound driven performance
Powered by Sennheiser TrueResponse transducer, a 7mm dynamic audio driver that delivers a high-end sound experience with full bass. Fine-tune the sound experience to your taste with a choice of presets and an intuitive equalizer through the Smart Control App.
Secure customized fit
Customize the ergonomic fit of your SPORT True Wireless earbuds with a choice of ear adapters in three sizes and four different ear fins, so they stay comfortably in place during any performance.
Tough design
There’s no need to slow down when conditions get tough: the sleek durable design has an IP54 rating so it can easily handle sweat, rain or workouts on the beach. Delivering 9 hours playback time and a further 18 hours with on-the-go charging via the case, for a total of 27 hours.

Why Buy?
Active earbuds that actually stay put during workouts
The Sennheiser SPORT True Wireless earbuds solve the frustrating problem of audio gear slipping out during exercise, giving you reliable sound that moves with you through any workout.
Your runs and gym sessions become more enjoyable with rich, full bass sound that keeps you motivated, while the secure customizable fit means no mid-exercise adjustments. The clever adaptable acoustic system lets you switch between open ear adapters to stay aware of traffic and surroundings, or closed adapters for complete sound immersion when you want to block out distractions. With 9 hours of playback plus 18 hours from the charging case, you get 27 hours total before needing to plug in.
The IP54 dust and splash resistance handles sweat, rain, and beach workouts without worry, while multiple ear adapter sizes and four different ear fins ensure they stay comfortable during long training sessions. The durable black design works equally well transitioning from gym to office, and the compact charging case fits easily in your gear bag or pocket.
