FAQs & How-Tos

  • aptX Audio Codec Support
    This headphone does not support aptX, aptX HD, aptX Low Latency audio codecs.
  • How do I get a secure fit with the Headphones?
    First, it is very important that you use the correct size enhancers (rubber tips). While the tips may appear too large, these do not go all the way into your ear canal. The enhancers are supposed to fill the entire bowl (concha) of your ear, so please be sure to try both sizes to ensure a comfortable fit. To properly put them on, first make sure you have the Right and Left earbud in the correct ear. Next, gently insert the enhancer into your ear with a forward motion towards the jaw, twist and lock into place. If you’re unable to find a secure fit with both sizes in the box, we can send you a complimentary sizing pack with two additional sizes. Please email us from our Support Page at https://www.jbl.com/support-contact.html to request yours today.
