The 7hz Timeless earbuds have superior overall and music sound quality compared to the Marshall Major IV headphones, which could provide a more immersive music listening experience. However, the Major IV offers significantly better microphone quality, making it more suitable for calls and meetings. The Major IV headphones also have a much longer battery life, which is convenient for extended use without frequent charging, and are more portable due to their folding design. The Timeless earbuds might offer a more detailed audio experience but lack wireless capability, limiting their use during exercise or on the move, whereas the Major IV are more versatile thanks to their wireless option. If noise isolation is a major concern, neither have active noise cancelling, so the difference in isolation quality is minimal. Therefore, if you prioritize sound quality and are okay with using a wired connection, the 7hz Timeless could be the better choice, but for everyday convenience, battery life, and versatility, the Marshall Major IV might serve you better, especially considering the price difference.

"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."

"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)."
