I always take my own Bose 15, but usually I get soft crackling when plugged into the AC socket (J or Y). There is a thread explanation somewhere here, to do with the structure of the plug Vs receptor connection points.

Ditto LH when I last flew them.

capebretonboy - don't you get this?

If its a noisy item or movie on the IFE, it might be tolerable, but last flight I switched back to the AC head sets.
