I have just purchased these headphones and they paired perfectly with both my iPhone and iPad.  The sound quality with music playback is great, but when watching a movie through the Apple TV app, the quality is poor and the sound is so quiet, it is barely audible when on a plane.  The same movie sound is loud and perfect with apple’s wired headset, so there seems to be an interface issue with IOS.  How can I resolve this.  The main reason I bought them was for watching movies on planes so I feel a little cheated.
