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

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. 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.

Secure customized fit

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.

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.

Product did not work. Right earbud never turned on. Ive used wireless earbuds for years and I am truly disappointed that a $200 set of earbuds can be such low quality that it does not even work. Sennheiser support is horrible, the only option for myself is to request a refund and order another pair. No compensation or exhange. Another company that is past its prime, riding on the coattails of its past success.


excellent sound. love the touch on them when i’m running. very easy to use and i like how both sides have functions and picking up a call is the same function for both sides. very easy. fits perfectly in my ear. very secure. my deduction of star is because of volume. however, maybe it’s safer for me since i’d rather not go deaf later on in life lol


Works perfectly

Love it....

Great value.

Great sound, works very well with the Sennheiser Smart Control App and feels secure even on long runs outside. I enjoy the strong bass and clear beat to motivate me for faster workouts. Better than I expected and I have several Sennhesier headphones and have come to expect exceptional quality.
