If you prioritize a budget-friendly option with a microphone that's best-in-class for calls and meetings, and if gaming is important to you, the JBL Quantum 100 is ideal as it's a wired over-ear headphone with very good gaming and TV scores; however, it lacks wireless convenience, noise isolation, and portability. Conversely, the JBL Tune Flex, a bit pricier, offers very good overall sound quality with the versatility of being wireless and additional features like low latency mode for better sync during gaming and videos, sweatproof certification for exercise, active noise cancelling for travel, and an app equalizer for sound customization. They are stemmed earbuds, so they're more portable and provide better use during exercise, but they do have a poorer mic quality. 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."

"JBL is offering a similar design and arguably better resolution than the more expensive AirPods 3rd Generation. Add to that a comfortable and versatile fit, an equalizer and pretty decent ANC, and you’ve got a quality wireless earphone. I would have loved longer battery life and more crystal calls, but for the price, you can’t complain. A solid deal overall."
