I listened to these briefly at a local Microcenter after being attracted by their...interesting aesthetics. Source was my Oppo HA2-SE, lossless FLAC via USB Audio Player Pro out of my HTC 10. I can't speak in detail since I wasn't planning on sharing my thoughts, but I came away thinking they were awful, very congested sounding. The Audio Technica MSR7's next to them sounded much better to me at the time at less than half of the price (although they aren't really my taste).
