The JBL Quantum 100 headphones offer a good microphone quality and are particularly suitable for gaming due to low latency, but they are not as comfortable for long listening periods and are less portable compared to earbuds. The KZ ZSN Pro earbuds, being more affordable, provide better overall sound quality and comfort, which could make them a preferable choice for music and general use, and they come with a detachable cable for better durability. However, they lack gaming-focused features like virtual surround sound and the sound isolation is similar to the Quantum 100, which is moderate. Consider your primary use—gaming or music listening—when making your choice. 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."

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."
