If you prioritize battery life, exercise use, and want to manage your earbuds directly from a smart case, the JBL Live Flex 3 may be a better fit, as they also tend to be more affordable and have a longer battery life with a handy LED touch display on the case. However, for superior sound in music and better noise isolation, the Sony WF1000XM4, while costing slightly more, offers high-quality audio and active noise cancelling. The Sony WF1000XM4 is also better suited for air travel due to its noise cancellation capability, though it has a shorter battery life compared to the JBL. Keep in mind, the WF1000XM4's app provides additional features like equalizer settings and 360 Reality Audio for immersive experiences, which could be significant if you're looking for an earbud that offers extensive sound customization.
