Pairing 12 Pro Max with Bluetooth speakers

I have several Bluetooth speakers that I have not been able to connect with IPhone 12 Pro Max. I go to settings, then Bluetooth. The Beats flexible earbuds by Apple connected instantly. In this screen where you “connect other devices”, the tiny circle indicator just continually circles as though looking but never connects. I want to connect:

• 2 small travel speakers
• Bose portable speaker

Appreciate any suggestions!
