Can you connect multiple ear buds to one iPhone

Generally, no, but you can use audio sharing with specific models of Apple or Beats headphones on compatible devices*.

How to start sharing

1. Connect your AirPods or AirPods Pro, your AirPods Max, or your Beats headphones to your iOS or iPadOS device. 
2. Tap the AirPlay button  in Control Center on your iPhone or iPad, on the Lock Screen, or in the app that you're listening to.
3. Tap Share Audio.
4. If your friend has AirPods or AirPods Pro, hold them close to your device with the AirPods inside the case and open the lid. If your friend has AirPods Max, hold them close to your device. If your friend has Beats wireless headphones, put them in pairing mode and hold them close to your device.
5. When you see your friend's headphones appear on your screen, tap Share Audio.

How to stop sharing

To stop sharing, tap the AirPlay button  in Control Center on your iPhone or iPad, on the Lock Screen, or in the app that you're listening to.

Tap the checkmark  next to the headphones you want to stop sharing with. When you stop sharing audio, you also disconnect the second set of headphones.

* You need a compatible iPhone, iPad, or iPod touch with the latest version of iOS or iPadOS, and you both need compatible wireless headphones.
