If you prioritize a built-in microphone for clear calls and gaming, the JBL Quantum 100 is the better choice as it offers excellent mic quality. However, if you're seeking superior overall sound quality, especially for music listening, the KZ ZSN Pro stands out with its higher score in that area. Both options are wired and offer similar levels of noise isolation and comfort, but the JBL Quantum 100 scores higher in gaming, while the KZ has a detachable cable and better build quality, which might be important if you're looking for durability. Neither has active noise cancelling or wireless capabilities, so consider these tradeoffs based on your specific needs such as gaming, calls, music, or durability. 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."
