Overview

JBL Signature Sound with Hi-Res Audio
12 mm drivers powered by JBL Signature Sound deliver crisp detail, deep bass, and natural balance. Hi-Res Audio Wireless brings out every nuance of your playlists, podcasts, and calls, making everything you hear sound more alive while JBL Spatial Sound transforms ordinary stereo into a natural, three-dimensional listening experience.

Smart Charging Case™ for a seamless experience
The redesigned Smart Charging Case™ doubles as your earbud controller with a simple interface that makes interaction easier than ever. Its intuitive display lets you adjust volume, switch tracks, manage ANC or Ambient Sound, and fine-tune your EQ—no phone or app required.

True Adaptive Noise Cancelling 2.0, real time calibration
Advanced adaptive processing monitors your surroundings in real time to block out distractions and unwanted noise. Stay immersed in silence, or use the JBL Headphones app to control how much of the outside world you want to let in. With fully adjustable Ambient Sound control, you can choose exactly when to stay focused and when to stay aware. Smart Talk automatically mutes your music whenever it hears you speak, so you can have a quick chat without reaching for the pause button. Use the JBL Headphones app to fine tune the Smart Talk settings.

Move through every moment of your day, effortlessly in tune with JBL Live Flex 4. JBL Signature Sound with Hi-Res audio accuracy and Spatial Sound makes every playlist, podcast, and voice call sound sharper, richer, and more alive. True Adaptive Noise Cancelling 2.0 automatically clears away distractions, while Smart Ambient keeps you connected to what’s around you. Just tap the even more convenient display on the redesigned Smart Charging Case™ to adjust volume, skip tracks, or fine-tune your sound—while your phone stays in your pocket. Six microphones with AI-trained noise reduction keep your voice clear and natural, while the streamlined Flex-style design stays secure through commutes, light workouts, and late-night listens. With up to 50* hours of playtime and IP54 water- and dust-resistant durability, Live Flex 4 connects you seamlessly, from the responsibilities of your day to the soundtrack of your night.
