What IEM - universal or customs - sounds closest to a de-foamed HD600 for around $300 or less?* I need a portable better than my JLab J3,** which doesn't fit me right (so basically I'd prefer a nautilus-shaped universal) and also I'd like to get something better, specifically, sounds close to the two cans I have at home. Sold my iPod Video recently, but I'm looking to use this unamped with a J3 that I'll get soon.*** I sometimes bring the SR225 out but it's a transportable for the most part, not to mention the tropical climate has prevented me from attempting to walk around with those earpads. *Or a universal that will sound that way with certain tips, or when re-shelled **Kinda happy with the sound; wide stage on most instruments but sometimes **Will also get an X3 and E11 but these aren't out yet so no reviews; plus I need the J3 to be more portable with this - thin size fits in pants pockets with a plastic hardcase, but isn't as bare-bones as audio-only players, specifically the ultra-portables. Need these for commuting and any time I have to be anywhere waiting or cueing up.
