Thx both for the replies.
After some research, feedback and reviews, the A20 are some step forward because the new ones seem to be lighter and not so durable as the A20 and I didn’t try to wear them with its process to find the right size of the earbuds.
I’m going to use the BT feature only to connect the iPad and I could use the classic cable (I don’t think to use it to receive or make call because in Europe we do not need them to pick up the IFR clearance, and we know that the cell network doesn’t work above some thousands feet AGL and at the moment this is the only case to have the BT version)
