Hi, I bought a new jbl bluetooth headphones and I didn't notice that it have no aux port.
I want to connect it to my old mp4 via bluetooth aux dongle adapter. The problem is that i have no buttom to accpect the devices cuz they have no screen and they are only scanning for devices and not catch them.
Headphones model: jbl 450bt

Any suggestions please?

The issue is with the adapter you are using, any questions about pairing things to them would be to their support or instruction manual.

1. Make sure you have the right adapter (Transmitter, not receiver)
2. Usually you have to place your headphones in Pairing mode first. Some BT transmitters then connect to whatever they can.
