i just got a pair of marshmallows yesterday after hearing all the hype.
theyre pretty good for the money and are very modable.
though i dont think theyre better than the E2c as some have claimed.
ive already changed the tips on mine and removed the paper screen.
i still need to find some extra porous foam to tame the sibillance.
here's a quick webcam pic of mine with a pair tips from my E2c.
the fit is much better.
