Anyone know how to wire two 360 mics together to use as headphones?

I want to create some headphones for my phone and the 360 headset works but I have 3 headsets so I was wanting to wire two together to have a left and right and just taking off the mic, anyone think they know how to do this?

There should be 2 connections on the back of each headphone element.  Connect one connection to the ground shield of some grounded 2 conductor wire, then connect one conductor to the other connection of the element.

Then on the other phone connect in the same order using the other conductor and the ground cable.

Now connect the plug like in this diagram.
