Q: Wireless J bird earphones be connected to the iPhone six? Thanks

Hello, moranfromjohnson.  

Thank you for visiting Apple Support Communities.  

I am not sure which version of these headphones you have.  However, most Bluetooth headphones work with the iPhone.  Here is some more information that explains the supported profiles and how to pair the devices.  

iOS: Supported Bluetooth profiles

iOS: Third-party Bluetooth accessories

Cheers,
