If you prioritize high-quality sound reproduction and noise isolation, the Etymotic ER4XR is superior but comes at a higher cost. They offer a more neutral sound and excellent passive noise isolation due to deep ear insertion; however, they might be less comfortable and lack features such as a microphone. Alternatively, the more affordable Soundcore P20i offers good sound quality and added features like wireless connectivity, a built-in microphone, and sweatproofing, making them a versatile option for exercise, calls, and general use. They are also more comfortable for extended wear but do not isolate noise as well as the Etymotics. 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."
