The Antlion Kimura Duo might be a better fit for you if you prioritize a wired connection, higher comfort, and superior sound quality for music and gaming. They are known for a better microphone quality, making them suitable for calls, but they have average noise isolation and might not be the best option for noisy environments. On the other hand, the Grado GT220 offers wireless convenience, a generally higher overall sound quality, and built-in controls which are absent in the Kimura Duo. They also support wireless charging and are lighter, which aids in portability, but they might not be the ideal choice for calls or gaming due to lower scores in those aspects. If you engage in physical activities or travel frequently, the Grado GT220's sweatproof certification and longer battery life can be significant advantages. 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."
