If you’re looking for wireless freedom and premium features like active noise cancelling, LDAC codec for high-quality audio, and a touch display on the case for easy control, choose the JBL Live Flex 3. They offer better overall sound quality, are sweat and dustproof, making them great for exercise, and they have a long battery life. However, for gaming or watching TV, their potential for high latency could be an issue. In contrast, the JBL Quantum 100 is much less expensive, offering the basics with a wired connection, great mic quality for calls, and a solid build for gaming. They don't have active noise cancelling or wireless capabilities and are less suitable for exercise or travel due to the lack of sweatproofing and their lower portability. 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."
