I wonder if this is normal since I am new to BT headphones.

I open the boom and the headset connects, but then 10 seconds later disconnects. If I get a call, I press the button, it reconnects - but doesn't answer the call.

To end a call I press the button, call ends and it disconnects.

My impression is that once it is connected, it stays that way and I should just be able to press the button to answer or end calls.
