If you prioritize a microphone for clear calls and gaming, consider the JBL Quantum 100 as they have excellent mic quality and are good for gaming. However, if music listening is your focus, the KZ ZSN Pro X with their very good build quality and decent sound may serve you better, especially if you're looking for a budget-friendly option. The KZ ZSN Pro X also has a detachable cable, which adds to their durability. For comfort, both are rated as good, but the over-ear design of the JBL may be more comfortable during long sessions for some users. Neither option supports wireless connectivity, so if this is important to you, neither would be suitable. Keep in mind, the JBL is tailored to provide a virtual surround sound experience which could enhance gaming and movie-watching, whereas the KZ lacks this feature. Give Feedback

CNN Underscored
Wes Davis | July 2023
"I appreciate a functional piece of tech as much as I do gear on the bleeding edge, and the JBL Quantum 100 certainly falls in the former category. The sound is reasonably good, the built-in microphone is surprisingly reliable and it has a thoughtful design for the price. It lacks the convenience of Bluetooth, sure, but sometimes it’s nice not to have to worry about the finicky nature of wireless communication and go with good old hard-wired tech."

"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."
