If you're on a budget, the KZ ZSN Pro X earbuds are considerably less expensive and offer good overall sound quality with very good build quality but have poor mic quality and no wireless capabilities. They're good for listening to music and watching TV, but not recommended for calls and meetings or gaming due to their poor performance in those areas. The Marshall Major IV headphones are more expensive, but provide excellent sound quality with excellent mic quality, making them suitable for calls and meetings. They are also wireless with a long battery life, convenient for mobility. The headphones lack effective noise isolation, which might be an issue in noisy environments, and aren't the best choice for exercise, but are very good for air travel due to their extended battery life and comfort. So, if you need a versatile pair of headphones for various use cases including excellent performance during calls, and don't mind spending more, the Marshall Major IV would be a better choice.

"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."

"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)."
