My GoAir true wireless air buds won’t sync with my iPhone 7

Thanks for posting in the Apple Support Communities arline116,

We understand you're having trouble pairing Bluetooth headphones with your iPhone 7, and you linked here from Connect your AirPods and AirPods Pro to your iPhone.

If you're not seeing your headphones appear in Bluetooth settings at all, you may need to consult the manual for steps to put them in pairing mode, or reset them.
