These are the ones I use -- http://www.maxellcanada.com/press_releases/2004/noise_cancel_headphones.html I have middle-aged ears with a definite roll off beyond 6 or 7 khz... so as far as the fidelity is concerned... who knows. What I do know is that "conversation" frequencies "sound" slightly warmer with the NC "on" - but that might be a result of how the "anti-noise" system works in the Maxell's - Most of the sound that I will be dealing with in Hawaii will be whatever the frequencies of "surf" are -- and a lot of that is subaudible -- and VERY loud... So we shall see. DXing last year with a modified E100 and Sony medium "cans" (not all ear encompassing) was fatiguing. Keep in mind that these are rather unusual dxing environs. If I take my Wellbrook ALA100M with some wire and cable I will be DXing in relative luxury (peace and quiet) The plan is: Carry a hard-case (not a Pelican) with me w/ -Eton E1 -Zoom MP3 recorder -Sony MD -Stock E100 -ALA100M + Power supply -Copy of my Amateur radio license & -Importation paperwork from Canadian Border Services and hope that Homeland warms up to me -- they generally do (I am ex-military, worked as civilian for Defense and am currently a civil servant who volunteers for some civil defense programs...) so I am pretty low on the threat to national security index. :-) I have debated this over and over again with various radio geeks and hams and the consensus appears to be: Traveling with radios? Carry them on. Checked ham gear, if fancy can be carted off my baggage handlers if insecure. I have nothing but praise for homeland and TSA - and have had nothing but gracious and professional treatment. -- ..........................................................................................
