If you prioritize wireless convenience and active noise cancelling for travel or noisy environments, the 1More Sonoflow is a better fit; they offer great noise isolation, a longer battery life, and are foldable, making them quite portable. However, the KZ ZSN Pro X, despite being wired and lacking noise cancellation, is much less expensive and provides good sound quality, especially if you're interested in a more balanced audio experience and don't mind purchasing additional cables. Choose the KZ ZSN Pro X if you're on a tighter budget or if having a detachable cable and the option to customize your audio with different cables appeals to you. Give Feedback

"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."

Jasper Lastoria | April 2023
"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."
