For immersive music listening, the Marshall Major IV headphones provide superior sound quality and have a convenient built-in microphone, making them ideal for high-fidelity audio enthusiasts. They are also equipped with active noise cancelling, which is a significant advantage for reducing background noise during travel or in noisy environments, and they have wireless capabilities for convenience. In contrast, the KZ ZSN Pro earbuds are less expensive and feature a detachable cable and ear hooks that might be better for exercise due to a more secure fit. They lack wireless functionality and noise cancelling but still offer decent sound quality and are wired, making them potentially suitable for those who prioritize budget and a physical connection over wireless integration and noise isolation.

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."

Jasper Lastoria | September 2023
"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)."
