If you prioritize excellent music quality and don't mind an on-ear, open-back design that doesn't isolate noise well, the Koss Porta Pro might suit you; they're great for music and TV but less so for calls and noisy environments. On the other hand, if you're on a budget and prefer earbuds with a closed design for better noise isolation, the KZ ZSN Pro X could be a better choice. They offer a good balance of sound quality for music and videos, but may not be ideal for exercise or high-movement activities due to their stemless design. Keep in mind, the Porta Pro is more suited for home use while the ZSN Pro X offers more portability. Give Feedback

"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."

"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."
