The JBL Tune Flex earbuds are better for portable use and exercise with their low latency mode and sweatproof certification, making them suitable for active lifestyles and gaming on the go. They also have good noise isolation and an app with equalizer settings, though their sound quality and mic are less impressive. The Marshall Major IV headphones boast longer battery life and superior sound quality, which is beneficial for enjoying music for extended periods. However, they aren't as convenient for exercise or travel due to their on-ear design and lack of sweatproofing, but their built-in microphone performs excellently for calls and meetings. If you prioritize portability and an active lifestyle, go for the JBL Tune Flex, but if long listening sessions and call quality are more important, the Marshall Major IV might be the better choice.

"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."

"The Marshall Major IV shares quite a bit in common with its predecessor, but a key upgrade appears to be softer ear cushions. They make upgrading worth it. As a set of basic wired or wireless headphones the Major IV ticks most boxes by remaining easy to use, and fairly comfortable (at least, as on-ear headphones go)."
