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."

"No other earphone I have listened to in the past 12 months has given me as much joy as the Thieaduio Monarch MKII. One of those IEMs will make you question where we can go from here. The sound is jaw-dropping, leaving you wanting more and more. It makes you want to run through your entire music library and reevaluate. It makes you not feel bad about paying full price for them, especially in a hobby where buyers' remorse is genuine. For me, it's top tier, rivaled by a few but not surpassed."
