Innovative Technology Bluetooth Headphones

Is it IR or bluetooth ?? This bluetooth transmitters can be paired with other BT headphones?

The ITHW-858B uses an IR signal, the transmitter cannot be paired with Bluetooth headphones.

We are senior citizens planning a trip to Paris and wanted these for the flight. I can not connect the headphones to my blue tooth. So I can not use these yet with our computer. Whats up?
