Fist time i use this z1000, it did not impress me at all. I feel like a dull sound and not open. until i realized that i need to get used to it before i can enjoy this cans. After i have had brain-burn in..spend about almost a week...than i started to enjoy the lush of its mids. Excellent for vocal song. Thou sometimes i feel like the sound staging is not that good. Is a bit too narrow. The bass need to be a bit punchier so it can suitable for pop/rock songs as well. It does not mean they are bad. Still good tho. Treble is fine. And the MIDS...this is part where i can forget all the cons. The mids is very, very good. Listening to vocal songs is just that excellent. The clarity, detail, and they way they reproduce the vocal is very enjoy to listen although is a mid-centric kind of sound. Is like a life-like sound i may call. Considering the size of this cans, the fit, the weight, i think i consider this is an excellent semi portable cans u may carry everywhere you go...especially for those who like vocal song...this is a must have cans.
