Very resolving and well tuned. Note weight leans thin. First IEM that I can say I definitely hear the BA timbre. Could use more down low. Pressure build is uncomfortable. Previously Owned

Pretty alright overall. Warm and reasonably well-balanced in the upper-midrange and lower-treble unlike some of Fiio's other IEMs.
