Sound driven performance

Signature sound Powered by Sennheiser TrueResponse transducer, a 7mm dynamic audio driver that delivers a high-end sound experience with full bass.

Built-In Equalizer Fine-tune the sound experience to your taste with a choice of presets and an intuitive equalizer through the Smart Control App.

Your workout, your sound

Adaptable Acoustics 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.

Focus and Aware 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.

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

Splash, dust and sweat resistance 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.

Peak endurance Delivering 9 hours playback time and a further 18 hours with on-the-go charging via the case, for a total of 27 hours.
