Hey, Bjbs97.
I see that after you accidentally removed your Beats Studio Wireless headphones Bluetooth connection from the devices listed on your iPhone, they aren't pairing again and your iPhone isn't seeing them. I'm happy to help.
Bluetooth basics—Studio Wireless
Disconnect & reconnect
- Push and hold the "b" button to disconnect your Bluetooth connection.
- To re-pair to your last Bluetooth connected device, press and release the "b" button.
If you can‘t connect a Bluetooth accessory to your iPhone, iPad, or iPod touch
If your Bluetooth accessory won't pair or connect to your iOS device, learn what to do.
Take care.
