Query: Awful Awful Waste of my money

The purpose of buying these headphones was to use them particularly on long-haul flights. However, when you put these headphones on and try to put your head back, the phones push themselves off your ears. No Good. I had to sit upright to listen to these properly. Sound quality didnt rock my world. And the big AA Battery department is ugly. I can't believe this product got signed off as being worthy of sale. What a shame.
