If you need earbuds primarily for gaming or frequent calls, and prefer a wired connection with excellent mic quality, the Antlion Kimura Duo with its boom mic may serve you well, despite being more expensive. For those looking for wireless earbuds offering good overall sound quality, lower latency for TV and gaming as well as sweatproof certification for exercise, the JBL Tune Flex could be a more cost-effective choice. However, mic quality on the JBL Tune Flex isn't as high, which could be a drawback for call clarity. Remember also that the JBL Tune Flex offers active noise cancelling, which the Antlion Kimura Duo lacks, this can be a significant advantage for noise reduction in noisy environments or during air travel.

"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."

"JBL is offering a similar design and arguably better resolution than the more expensive AirPods 3rd Generation. Add to that a comfortable and versatile fit, an equalizer and pretty decent ANC, and you’ve got a quality wireless earphone. I would have loved longer battery life and more crystal calls, but for the price, you can’t complain. A solid deal overall."
