Has anyone used a 1/4" Y adapter and 3.5mm-to-1/4" converter to pipe in music into their aviation headset? I have a standard aviation headset and would like to splice in some music for longer flights.  The aviation-specific adapters are overpriced at around $40.  Can i just use a 1/4" Y adapter and a 3.5mm to 1/4" converter, such as these?   Has anyone tried this with results?

Commercial 1/4 Jack audio headsets are stereo, signals to top and ring, body is ground... so you need to fiddle the wires so both signals go to the tip... Else you will.only hear one channel .. I don't advocate this use because if you are listening to.music you might miss calls about other traffic etc.. Your call.
