as tested on a scale from 1 - 10 :
Noise isolation: very good (7 - 8.5)
Bass Response : excellent (8.5 - 9.5)
Mid-range (vocal music) : acceptable (4.5 - 6.5)
Mid-range (Speech) : good to very good (6 - 8)
Treble : very good to excellent : (7 - 9)
comfort : very good (7 - 8)
Overall : very good (8 - 9.5)
Comfortable and snug, they don't fall out easily. The sound isolation is very good.
The bass response is outstanding. the treble is very crisp (too crisp sometimes) but mid-range suffers a bit during (normal) vocals which are almost drowned out by the bass and treble.
Compared to Genius HP-02 LIVE Earphones (which, for the price, are amazing) these have much nicer bass and treble, and about the same mid-range.
If price is an object ... go for the genius ... you can give them away if you don't like them and they come with a little velvet bag to keep them in.
Overall these in-ear are outstanding for the price. I recommend them for Dub-step, Heavy Bass, Pumping rock, Reggae, Rap, Ambient, classical music ... I don't recommend them for vocal/opera vocal classical/live rock (although they sound great ... the genius are more linearly responsive and therefore better all-rounders).
