FAQs & How-Tos

  • TUNE-FLEX: Does the JBL Headphones app give me any indications when I choose different Ear Tips mode?

    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).
  • TUNE-FLEX: Does the number mean different levels of ANC Tuning?

    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.

  • TUNE-FLEX: Why do I need to perform the “Ear Tip Sound Settings” after changing ear tips?

    Different ear tip types provide a different sound performance, depending on their shape. For a high-quality sound output, JBL specially tuned the sound according to different tips to fit your wearing preference. 
    o    The Open Ear Tips mode allows more natural, while letting the surrounding noises come through. 
    o    The Sealing Ear Tips provides more isolation from the surroundings.

  • TUNE-FLEX: What is the purpose of ANC Tuning?

    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.

  • TUNE-FLEX: What happens if I do not perform the “Ear Tip Sound Settings” check using the relevant ear tip?

    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.

  • TUNE-FLEX: What is the benefit of using “Open Ear Tips vs Sealing Ear Tips”?

    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. 
  • TUNE-FLEX: How can I choose the best sound to fit my ear tips?

    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.
