If you prioritize sound quality and are on a budget, the Koss KSC75 would be a preferable choice since they are noted for good overall sound and are significantly less expensive than the Marshall Major IV. However, they have an open design which doesn't isolate noise well, making them less ideal for noisy environments or air travel. The Marshall Major IV, on the other hand, has a closed design with better noise isolation, a built-in microphone, and is foldable which enhances portability. They also have a significant advantage in battery life for wireless use, with a feature of wireless charging, making them more convenient for extended use without worrying about cables. If you plan to use them for calls or video conferences, the Marshall's better microphone quality could be a deciding factor. Give Feedback

InEar Fidelity
Crinacle | June 2022
"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."

"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)."
