If you're looking for wireless convenience and active noise canceling for travel or busy environments, the JBL Live 770NC headphones are suitable, offering excellent noise isolation, built-in controls, and long battery life, making them good for air travel and work. However, they are not ideal for gaming or TV due to poor scores in those areas. On the other hand, KZ ZSN Pro X earbuds are a budget-friendly wired option with very good build quality and sound, suitable for high-fidelity listening with optional balanced audio cables. They lack wireless functionality, active noise canceling, and aren't sweatproof, limiting their use during exercise and for commuters. Choose JBL if wireless features and noise canceling are priorities, or KZ for a cost-effective, high-fidelity wired listening experience. Give Feedback

"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."
