The Westone ES3X, quite balanced IEMs with a bit more pronounced mids. Very natural sound with some warmth. Quite detailed and has nice depth to the soundstage for an IEM, but they lack in soundstage space and low bass power which I'd wish be more like the HD-800's precise, tight and powerful bass. I haven't heard any other high-end IEMs so I don't know whether the rest suffer from the same reasonable issues.
