If you prioritize comfort and noise isolation, especially for long flights or commuting, and are willing to pay a premium, the Bose Quiet Comfort Ultra Headphones would be a better fit; they offer excellent noise cancelling, are comfortable for extended periods, and have a longer battery life. However, they may not be the best for calls and might be overkill for casual music listening. On the other hand, if you are on a budget and need earbuds for regular, everyday use without wireless capability, the KZ ZSN Pro X offers good sound quality for its price, but with less comfort, minimal noise isolation, and no noise cancelling or wireless features. They also lack the sound quality for high-fidelity gaming or TV watching but can be used for exercise and provide a secure fit with ear hooks. Give Feedback

"The Bose QuietComfort Ultra Headphones are a credible step up from previous Bose ANC headphones, and they're built to hang tough with the competition for years into the future. No waterproofing is a bit of a letdown, but these headphones have the technical chops to make most quite happy."

"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."
