If you're looking for earbuds more suited for travel, calls, and a wireless experience, the JBL Live Free NC+ offers active noise cancelling, sweatproof certification, and overall better build and microphone quality, making them ideal for noisy environments and workouts. However, they have a shorter battery life without the case and may not be the best for soundstage or immersive listening. On the other hand, the KZ ZSN Pro X earbuds are wired, budget-friendly, and provide good sound quality with a strong build but lack advanced features like active noise cancelling, a microphone for clear calls, and the versatility for use during exercise. The choice depends on whether you prioritize wireless convenience and noise cancellation over affordability and a more straightforward audio experience. Give Feedback

"JBL has added great-sounding, rock-solid all-rounders with a pleasant, warm sound character to their range. They are equipped with a high level of functionality that can be customised via the app. Some compromises have to be made with the active noise cancellation, which has a discreet effect, while the ambient mode and the Talkthru function proved to be powerful despite a perceptible background noise."

"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."
