This is my first review, but I tried to give a review based on feeling rather than comparison with other IEMs.

I may be asking too much for a ~ 50$ earphones, but as my first pair of in-ears, and coming from headphones like Hd650 and sr80i's, I expected much more after having read some raving reviews.

It's not bad, I actually like the design, cable and ergonomics, but the sound is way too thick and laid-back. They are not bass-heavy. Bass might be at the same level as mids, but not very detailed and too thick.
Mids are fine. Their best part I guess.
Treble can be more felt rather than heard. Very few sparkle. Makes them rather lifeless especially if you consider that I'm coming from cans like HD25 and Grado SR80i. So you can call me biaised on this point, as I have no experience when it comes to IEMs.

Good value though, considering the build and accessories.

Oh, and the foam tips are really bad. They don't keep their form when you squeeze them, which means that they are almost back to their expanded form before you had a chance to put them in your ears. I later bought some audeos, and "real" Comply tips are like night and day compared to Vsonic's ones.
