>>106232158I had these when they released, it was one of the shortest hype trains imo.
Good overall closed back headphones, neutral sound with a little bit of bass boost and reduced treble, small congested soundstage and ok imaging, not very comfortable for me due to the small earpads, and the cooling gel is a gimmick.
Sadly it was forgotten due to the early headband mechanism problems, and release of the fiio ft1 after that, which killed the small hype that these had.
If you want it be sure to get one of the newer batches with improved locking mechanism (see picrel)
