The HID software for the jbl everest 300 update won't recognize my pair. Is there any other way to get the software update?

Asked by: Bar371
One important detail to remember when updating the Everest headphones is to use the USB cable that was included in the box. Also, try to use a different USB port available in your computer/laptop. Some cables are not suitable, and may cause the headphone to freeze, refusing to respond. Or they simply do not work at all. If you are still having issues, please submit a case at jbl.com/contactus and our Customer Service team will be glad to assist you further.

Which of your headphone products are latex free?

Asked by: Megs
We don't use latex in any of our headphones, in-ears have silicone eartips, and on-ear/over-ear use fabrics (nylon) and/or faux-leather, which is protein-based.

It's my first time to charge my JBL Everest 300 and it seems weird because there's no red light after I plug the USB charger on the headphone. Is this normal that it's not showing any light if its charging?&nbsp;

Asked by: mike_08
The charging light can be a little difficult to see. It is actually located underneath and towards the bottom the right ear cup. It should be solid red as it is charging and will shut off once it is fully charged. If you still do not see the charging light turn red or if you are having difficulties turning the headphones on, please contact your local JBL Customer Service for technical support.
