I have read alot of reviews on the grados and they seem to be amazing head phones. I would like the best sounding head phones for long trips. And when i said i want ones that cover the whole ear, i just thought it would give a better sound, but from what im reading, open air headphones (grados) are rated among the highest. Are these headphones loud to people i will be sitting next too? like on a plane? and since these are open air headphones, does that mean i will hear alot of ambient noise going on around me?
