FAQs & How-Tos

  • Trouble accessing the Google Assistant or Amazon Alexa on your Headphone

    First, ensure that you have the Google Assistant or Amazon Alexa apps installed on your device, depending on the voice assistant you want to use. Go to your app store to download the intended voice assistant app, then add your headphones as a device in the app if necessary. Finally, enable the intended voice assistant in the settings of the My JBL Headphones app and assign which earbud you want to use to control it. The voice assistant app must be open for it to work correctly. It can be opened from within the My JBL Headphones app by tapping the name of the required voice assistant after you have selected it for use and assigned a gesture to one of your earbuds to control it.

  • How to avoid Bluetooth Interference or Interruptions

    • Always have clear line of sight between your Bluetooth device (speaker, headphones etc.) and source device (Smartphone/tablet/PC etc). Be aware of obstacles in front of your devices.

    • Try to shutdown other products that have Bluetooth, but are not being used. They are often the reason for interference even though they are not being used.

    • Do not stand too close to your Wi-Fi router since a Wi-Fi signal is stronger and in many cases will "overlap" the connection.

    • Be aware of walls around you. Concrete and brick walls will often interrupt the signal, as it cannot pass through such thick walls.

    • Bluetooth signals cannot travel through water, which includes the human body. Make sure with wireless headphones to keep your source device and the receiver on the same side of your body.

    • Open spaces such as parks can cause issues for your devices, as open air is "bad" for any Bluetooth signal if it cannot reflect from objects around you.

  • Pairing issues with a Computer or PC

    In most cases when a Computer/PC/Laptop has issues connecting to a Bluetooth device (Portable speaker, Headphones, Active speakers), it's caused by your Computer/PC/Laptop's Bluetooth driver (software).

    The driver (software) should support the following Bluetooth protocols, to be able to play music/sound from your Computer/PC/Laptop:

    • A2DP (Advanced Audio Distribution Profile) driver for your Computer/PC/Headphones to transfer music.

    • AVRCP (Audio/Video Remote Control Profile) driver to send skip/forward/pause/play music to your device

    Always get the latest driver version available for your Computer/PC/Laptop.

    To download the correct driver (software), visit the manufacturer's website of your Computer/PC/Laptop. They usually have a "Support/Download" section where you can find the correct driver. Otherwise, we advise you to contact their support.

    The standard drivers provided by Microsoft/Windows system are not correct and will result in error messages (such as having to enter a PIN code), or pairing will not work.
