I have H2O audio but haven't had a chance to try it out yet. I saw someone the other day with a pelican that had the headphone attachment. First I've seen of those...not sure why they had it here..keep the dust out I guess.
I've always trusted pelican with my camcorder and camera. Whatever you get, make sure to test it before you use it with electronics, probably to be safe test it each time before use.
I hope in the future Americans are thought of as a warlike, vicious people, because I bet a lot of high schools would pick "Americans" as their mascot. -Jack Handy
