With intra Westone um pro 10, a made very clear even at high volume without having to play with the equalizer between each title that good live draw. Do not miss out on the quality of the original files, Flac or mp3 to 320, below is a little misery.
Should do even better with intra superior (gender ump 30, 3 lanes).
Viewing and really basic screen for 2014 but sufficient. Ditto interface.
=> This is the first very good sound, clear and precise, very strong if necessary.
Take my other headphones properly (open), Audio-Technica w10-vtg which still makes it a little better on my chain (but hey, the chain is less portable!).
Glad to buy but wonder if x3 could have been enough (according to critics not, but not the same price either!).
Well above the audio output of my mbp and incomparabe with that of a MP4 Player Archos 605.
