Fling wing
I have recently ( 2 months) purchased a set of Bose x like you when i first jumped into the Jetbanger with them on i started to hear sounds that were not normally there with our Dave clarkes.
I absolutely enjoy the Bose X without any dramas, except like John E said when you wear glasses it breaks the seal. and when you turn the ANR off its terrible! apart from that they are great as my hearing is only just good at the best of times!!
