: Treble is good, vocals can be heard clearly, bass is not too loud.
: Sounds crackling if too loud(from -5dB to 0dB)
I can't write detailed reviews but I just write about it from my experience.
Treble
The treble part is pretty good on this headphones. You can hear them clearly, but it will sounds crackling if the volume is too loud.
Midrange
Not bad, I can hear vocals clearly, and not too loud too.
Bass
The bass is [strike]kinda[/strike] too soft actually. You might need to tweak the EQ to make it louder, and crossfeed might help.
Soundstage
No soundstage, everything is just ordinary left and right.
That's all I can say. If you're looking for a cheap yet good quality headphone, this might be for you. It's comfortable too.
