Hello KHinrichsen11,
It sounds as though you're having issues with your Beats Solo3 continuously disconnecting from your iPhone, and you have to reset the Beats so they may reconnect with your iPhone. If so, you're on the right track with reaching a resolution by resetting the Beats. With the issue continuing, the next step would be to confirm that the firmware is updated. If your iPhone is running the latest iOS version your Beats would automatically stay up-to-date.
If your Beats are updated, the next step would be to test your Beats with another device to see if the issue persists. If the Beats disconnect when paired with another device it would be recommended to reach out to Apple via the Get Support website for additional assistance.
If you don't have issues when the Beats are paired with another device that would isolate the issue to the iPhone. You would want to see if the issue would occur with a different Bluetooth device paired with the iPhone.
Have a great day!
