JBL Pure Bass Sound with Spatial Sound
JBL Tune Flex 2 earbuds feature 12mm dynamic drivers that deliver powerful JBL Pure Bass sound. And whether you're listening to your favorite playlist, watching a movie, or playing a game, JBL Spatial Sound transforms the stereo sound from any source or device into a more immersive sound experience.

Adaptive noise cancelling with Smart Ambient
JBL Tune Flex 2 earbuds use Adaptive Noise Cancelling to tune out noises entirely or just let in as much of the outside world you want. Ambient Aware adapts how much of the outside world you want to hear, while TalkThru lets you talk with those around you—all without taking your earbuds out. The additional eartips allow you to choose how much isolation from the outside world you want.

6 mics for perfect calls and customized call experience
Two beamforming outer mics on each earbud pick up your voice and deliver it as clearly as possible, while one inner mic isolates noise. Environmental noise cancellation and echo suppression algorithms capture every nuance of your voice without any noise or distortion, even if you're outside on a windy day. Use the JBL Headphones App to customize what you and the people you're talking to sound like through your earbuds.
