The Etymotic ER4XR offers exceptional noise isolation and is built to last, but it lacks wireless capability and isn't as comfortable as other options. If you value top-notch sound quality and can manage a wired connection, the ER4XR might be worth its premium price. In contrast, the Sennheiser Momentum True Wireless 3 provides seamless wireless convenience, including active noise cancelling and features like app equalization and ear detection. Recommended for more versatile use like exercise, calls and meetings, or extended wear, they are a more affordable option without sacrificing much in sound quality. However, for truly critical listening or if you need every detail in your music, the Etymotic might still be the preferable choice despite its higher cost and lack of 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."
