Crystalline sound, comfort on the ears and a demonic precision for a helmet which, subtly without climbing in through headphones at high bass can give if one is his or mostly DAC card that goes well with ( I think of marrying him to a fiio).

And do not forget, the low flow mp3, must now forget. He is ruthless.
