[QUOTE="Mike Diack, post: 2847, member: 144"] Having just spent around 50 hours of my life in the last month on B777s, I continue to be astonished by how bloody awful the audio feed from the little personal AV system is. Is it just the $2 headphones they use, with their massive peak around 150Hz that makes them rattle or is the problem further back in the chain. I'm temped to wire a couple of mono 0.125" jacks up to a decent pair of cans and see if there is a difference. If this fails, electronics (in the form of a little amp and EQ) may help (this presupposes some knowledge of what lies on the other side of those two 1/8" holes on the seat arm). Anyone here got a day job at Boeing ?. M [/QUOTE]
