I wouldent chance them on a plane either.
usc goose, are you talking about the V6/7506? I've never heard the V6, but apparently they sound the same. Not sure why so many people say the 7506 has such bloated bass, because it's not any more bloated then the midbass of the HD600s, Grados, or at the worse the DT770 Pro's which have sickeningly bloated bass that isnt even coloration, rather distortion in it's severeity. I still can't understand how some people can enjoy this headphone with anything other than classical since it's less apparent, and the disgustingly low response helps with low frequency instruments (I can hear a clean 15hz on those things without elevating the volume much running response tests.)
