My iPhone 7 Plus Bluetooth Beats headphones show connected but won’t work several times a day. Have to reset to get them to work

My iPhone 7 Plus Bluetooth Beats headphones show connected but won’t work several times a day. Have to reset to get them to work. I have tried 5 different headsets with the same result. I have removed all Bluetooth devices except,Apple Watch 1st version. Turned off WiFi calling and anything else I can but it does not help. This has been going on since I,got the phone 6 months ago. Very annoying. When I make calls it will show connected but I can’t hear on my end and the other person can’t hear me. If I put it on iPhone we can hear each other but if I put it back still nothing. If I power down the beats and go through the slow painful power back up of the beats it still does not work. The only resolution is to restart the phone. I don’t even use the Bluetooth in my new truck. Kind of a joke.
