Re: Jaybird Tarah Wireless Sport Headphones Do Not Hold Bluetooth Pairing
You could try upgrading the iPhone(s) to the latest iOS version: About iOS 17 Updates - Apple Support
or
If already updated try re-starting the iPhone (re-establishes connections, deletes temporary files etc.)
and
Check if Low-Power mode is on / see if turning it off helps
If you still need help:
Re: compatibility:
You may need to check the manufacturer's instructions, or contact their "Support" via their website.
Eg: third-party (non-Apple) accessories may need firmware updates from the developer / manufacturer. The info. that came with the purchase or the manufacturer's website / support team/ would likely be able to help with that.
