If you prioritize sound quality for music and a wired connection, the 7hz Timeless, with good comfort and very good build, may suit you, especially if you're okay with external mic attachments for calls. However, for active lifestyles and modern wireless convenience, including features like active noise cancelling, sweatproof certification, and a Smart Charging Case with touch controls, the JBL Live Flex 3 would be the better choice, along with its app customizations and battery life enhancements. Keep in mind that the JBL's sound quality isn't optimized for focused gaming or TV sessions, whereas the 7hz might offer a better experience there despite its lack of low latency. Give Feedback

"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."
