I use Westone UM2's with my 3D and i find it acceptable. nothing else to compare it to though. i use volume + and adjusted the equalizer settings to my liking. clear and just the right touch of bass. what's voodoo sound? i wish though i could fine tune the volume. the rough increment is never my favorite thing on devices. if it was fine tuned increments for the volume control than i'd be much happier but i might as well buy a headphone amp.
