The Antlion Kimura Duo offers better overall sound quality, gaming performance, and comfort, with a high-quality mic and detachable cable, great for gaming or Zoom calls. However, it might not be the best for exercise due to a lower score in that area. On the other hand, the Etymotic ER4XR excels in noise isolation, which is beneficial during travel or in noisy environments, but its smaller size and lack of a microphone could be less convenient for calls. Despite its higher price, its compact build and superb noise isolation might be worth it if you prioritize sound isolation and listen in noisy places. Give Feedback

"Antlion Kimura Duo aren’t packed with features, but the ones they offer, work incredibly well. Especially the boom mic delivers very clean call quality with no distortion. If you explicitly look for gaming in-ear monitors with a reliable microphone, Antlion Kimura Duo are your best option."

"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."
