No, it does not work with iPad. Product specifications explicitly state it is not compatible with Apple iPad.

The cable can be used with the Jabra Evolve2 75 in the aircraft to transfer audio from the in-flight entertainment system to the headset. The Jabra Evolve2 75 supports connection via Bluetooth and USB-C, which means that it is compatible with an appropriate adapter or cable for audio transmission. As the cable has a 3.5 mm jack plug, it should fit into most in-vehicle entertainment systems that offer such a connection. Make sure that the in-vehicle entertainment system also has a 3.5 mm output to make the connection.

I don't know because I don't have any Airpods Max...

The cable has a length of 1m. We will add this information later, thank you.
