That sounds like a pain! Let's have a look at things.
Have you only used these headphones with an iPhone 11, or have you noticed this issue on other mobile devices?
If you're like me, and you prefer watching support videos, you will find guidance through our support video HERE. After you've checked that out, try the steps shown on our website HERE to walk you through clearing the pairing of devices.
Have a look at both and let me know if you find any improvement!
