If you prioritize sound isolation and critical listening, the Etymotic ER4XR would suit you, bearing in mind it's wired and may not be the best for exercise. For a premium, the Sennheiser Momentum Sport offers a range of modern features like wireless connectivity, a secure fit suitable for exercise, plus heart rate and temperature tracking. Its active noise cancelling and support for advanced codecs like AptX Adaptive also enhance the listening experience for different activities, but at a higher cost. Choose Etymotic for focused listening and cost savings, or Sennheiser for versatile use and modern features. Give Feedback

What HiFi?
What HiFi? | May 2015
"The Etymotic ER4XRs' top qualities are the detail and definition of the midrange, rewarding the closest listening. While the soundstage is large rather than gigantic, the excellent separation and spatial precision mean you can dive deep into music just as much as when wearing a pair of full-size open-backed headphones."

Amelia Schwanke | January 2024
"We hadn't been expecting a new pair of dedicated sports buds but the surprise was nonetheless exciting. I got to try out the new buds at CES 2024 and while they have stayed true to delivering that "signature" Sennheiser sound, with a wide soundstage and strong sense of detail, it’s the extra wearable tech inside them that stands out to me against the best workout headphones."
