06:45 clock: The flight attendant wakes me - I should buckle up myself, we end up the same. Next to me is a completely fatigued Americans. He speaks to me. I turn off my headphones and stow it. The baby cries still. The Americans asked me how I could sleep with the cry - I was probably the only one in a radius of 4 rows of slept he said. :-)
So the headphones are unique - an expensive investment. But who flies a lot or travel, for they are a "must".
The delivery is equal to the battery case. It is a "normal" AA battery that you get everywhere. In addition, an adapter plug mti which I could connect my headphones to the local entertainment system to date on all aircraft.
The cable is long enough, the sound is crystal clear. A small negative point: When you have a window seat and leans his head against the window no longer works! Gerauschunterdrückung the once the bow of the headphones touches the inner wall of the aircraft.
PS: Recently I've been flying the A380. Although that is pretty quiet, I was surprised how high but the noise level is if you take the headphones decreases briefly during the flight.
