In all the research I've done so far, the 2 waterproof headphones that get mentioned the most as the "best" options for underwater with the Equinox are the Patriot Headphones (http://metaldetecting.com/en/patriot-equinox-water-weq) and the Tony Eisenhower's Headphones. Has anyone actually used both and can accurately compare the 2 models? I'm talking in terms of volume underwater and comfort.
