If you prioritize sound quality and music performance, the 7hz Timeless would be the better choice with its higher music score. Conversely, the Antlion Kimura Duo scores higher for gaming and has a microphone, which makes it more suitable for calls, meetings, and interactive experiences. Both are wired earbuds with similar scores for comfort and TV/video use, but the Kimura Duo is also rated better for exercise and travel. The 7hz Timeless is priced higher, so if budget is a concern, you might lean towards the Kimura Duo, especially if you value versatility and the included microphone. Give Feedback

Kazi Mahbub Mutakabbir | May 2023
"7Hz picked a bold name for the Timeless and frankly, got very close to justifying their word choice. Most importantly, the Timeless are good to go in stock form, so you don’t have to worry about source-matching and such. I can recommend the 7Hz Timeless to those who do not mind a dash of brightness up top, want a taste of planar in IEM form, and want one of the most resolving pair of earphones in the $150 - $300 price range."

"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."
