Sennheiser SPORT True Wireless Headphones

Discover sports-optimized control of how you experience sound and hear your environment.

Tailor your sound experience for the level of immersion or awareness you prefer. The 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.

Sennheiser SPORT True Wireless Headphones

Enjoy a comfortable and secure fit no matter how intense your exercise.

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.

Sennheiser SPORT True Wireless Headphones

A unique hybrid feature: Adaptable Acoustics

To meet the demands of as many athletes as possible, the new Sennheiser SPORT True Wireless are literally two products in one, with two styles of ear tips designed for two very different types of workouts. Sennheiser has named the feature, Adaptable Acoustics. When you need to focus, the closed ear tips provide passive noise cancellation for blocking out the noise during your workout in the gym or at home. The open ear tips provide low occlusion for improved comfort and increased situational awareness. For your next run, choose the open ear tips to greatly reduce the discomfort of hearing body-borne noise and to benefit from improved situational awareness. Put on your favourite track. Run. The bucket is off. Enjoy.
