JBL Pure Bass sound
The JBL Wave Flex 2 headphones are equipped with 12mm dynamic drivers that deliver exciting JBL Pure Bass sound.

Smart Ambient technology
The JBL Wave Flex 2 headphones feature Smart Ambient technology. Ambient Aware adjusts the amount of outside world you want to hear, while the TalkThru feature lets you talk to others – all without removing the headphones.

4 microphones for clear and crisp calls
Two microphones on each earbud capture and transmit your voice clearly while canceling out ambient noise, so you can make clear, crisp calls, even when walking through a busy park on a windy day.

Water and dust resistance
The JBL Wave Flex 2 headphones have an IP54 water and dust resistance rating, so you can use them in rainy or windy conditions. The case is also IPX2 water resistant, so you don't have to worry about leaving them at home.

JBL Headphones app
With the JBL Headphones app, you can choose an EQ that suits your style or customize your own. Voice prompts in multiple languages give you helpful information, like whether your battery is low. Or unwind and recharge in Relax Mode by choosing one of five soothing sounds, like gentle ocean waves or a crackling fireplace.

40 hours of playback, fast charging
Enjoy 10 hours of playtime, plus three full charges (30 hours) in the charging case. Need an even faster charge? A 10-minute charge via USB Type-C cable gives you three more hours of playtime.

Connecting to multiple devices
Connect the JBL Wave Flex 2 headphones to two Bluetooth® devices at once and seamlessly switch between them. So if you're watching a video on your tablet, you won't miss a call on your mobile phone.

Worry-free Bluetooth® connectivity
