The bass is full to drown up in very low frequencies in there without something else, the highs are fine resolution but not too superficial, the sound is very transparent without being too filigram - it's just all right, with these headphones listening to listening is very interesting (Lee Ritenour, Hiroshima, Nathan East, George Duke, NILS, Kevin Eubanks).
The auditory sensations originated on an iPod Touch 5G, a Iphone6 and a Cowon J3. The headphones have left on all players such a good impression that the originally envisaged by my purchase of a Walkman NWZ-ZX2 was made spontaneously, because the performance of the headphones with the player already available does not need such a costly optimization.
To cut a long story short: strong buy recommendation!
