Pure bass, zero noise

Take on your day one song at a time with JBL Tune Flex 2 true wireless earbuds featuring Adaptive Noise Cancelling. They deliver up to 48 hours of exceptional JBL Pure Bass Sound and JBL Spatial Sound, while the ergonomic (and water and dust resistant) design gives you all-day comfort in any weather. Enjoy perfect-sounding calls without ambient noise, all managed using intuitive touch controls. With Adaptive Noise Cancelling and Smart Ambient technology, you can tune out the world, or choose how much you engage with your surroundings. You can even personalize your sound experience with the JBL Headphones app and tailor audio around you with Personi-Fi 3.0. Pop in the JBL Tune Flex 2 and experience your world your way.

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.
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.
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.
Hear and feel every note of your playlist. Shape your audio to match your personal listening profile with interactive customization tools that use precise information about you and your preferences to provide the exact sound curve that suits you best.
Choose open ear tips to stay aware of your surroundings while wearing your earbuds. Or seal off the world and improve the passive noise cancelling with your choice of three sizes of sealing ear tip.
Enjoy up to 8 hours of playtime, plus another three full charges (24 hours) in the charging case with ANC on, or up to 12 hours plus 36 hours with ANC off.
Your JBL Tune Flex 2 are IP54 water and dust resistant, so you can rely on them even in rainy or windy conditions. *Earbuds only

FAQs & How-Tos

  • As with all in-ear headphones, our range of True Wireless Stereo headphones can be susceptible to a build up of dust and earwax. This can cause low volume on one or both earbuds, or balance issues (e.g. right earbud is louder than the left earbud). To reduce the likelihood of these issues occurring, it is a good idea to periodically clean your earbuds. Clean the earbuds by removing dust and wax after each use, using a pointed toothpick to remove larger amounts and a small amount of rubbing alcohol applied to a cotton swab for final degreasing. Remember to clean the charging points on the headphones and inside the charging case.

    If you are experiencing volume or balance issues, always check for wax and dirt in and around the earbud and driver and complete cleaning of the earbuds as described above. If the issue persists, there may be earwax/dirt stuck in the small holes in the grille in front of the driver, preventing sound output. To resolve the issue try dipping the affected earbud tip into a solution of lukewarm tap water and a small amount of dish soap (washing up liquid). The earbud tip should only be put into the liquid up to a maximum depth of 1-2 mm only (see images below). Immersing the earbuds in water or putting the earbuds in water at a larger depth than this could void your warranty. Keep the earbud tip in the water for about 2-3 minutes, then wipe/clean the grille with a small brush (such as a toothbrush). This should remove the wax and resolve the volume/balance issues.

  • Yes, the headphones have Multipoint Connection, which allows you to switch seamlessly between the connected devices. 
  • Double-tap the button on the right earbud, then on the third tap - press and hold the button for more than 5 seconds (until the unit shuts off). 
    This restores the earbuds to the factory defaults.
    TWS must be connected to perform the reset, so neither of the earbuds should be off or in the charging case.
    It also may be necessary to remove or forget the earbuds from the list of paired Bluetooth devices in order to pair again.
  • This headphone is supported by the My JBL Headphones App.
  • JBL Tune Flex is packed with two types of ear tips. These are called “Open Ear Tips” and “Sealing Ear Tips”.
    When you click the Ear Tips mode, you will hear a tone to remind you of the different sound modes (Voice prompts not ready yet).
  • Numbers 1-6 do NOT relate to ANC level, but you can find the optimal performance for your ears by selecting one of the bubbles.

  • You can choose the “Ear Tip Sound Settings” feature in the JBL Headphones app or activate this feature by tapping three times + holding the left earbud.

  • If you do not perform the "Ear Tip Sound" setting after changing the ear tips, i.e., using the “Open Ear Tips” for “Sealing Ear Tip” mode, the sound will not be as natural as with “Sealing Ear Tips”, and vice versa.

  • JBL Tune Flex is packed with two types of ear tips. These are called “Open Ear Tips” and “Sealing Ear Tips”.
    “Open Ear Tips” allow you to be aware of your surroundings while using the earbuds. “Sealing Ear Tips” provide you with greater sound isolation and a more secure fit. 
  • Due to the various human ear canal, there are different needs of each user for ANC. When you change ear tips, we suggest you reselect different modes of ANC Tuning to enjoy the best ANC experience. Each ANC Tuning represents different ANC presets, that way you can find the one that best fits your taste.
