Why do my wired headphones need Bluetooth?

Hi Muhammadasad45,

Thanks for using Apple Support Communities. We want to help answer any questions you have about your headphones. It sounds like you're being prompted to pair headphones that are not Bluetooth enabled. If that's the case, restart your device and test if this continues. A restart is a simple step that can resolve a variety of concerns. See how here:

1. Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. ... 

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.

See more about those steps here: Restart your iPhone - Apple Support

If this continue after restarting, let us know exactly what happens when you connect your headphones and any prompts/errors/alerts you're seeing. We'll go from there.

Thanks.
