Get neither of them.
Go for Kanon MD-52 on ecrater
7$+2.50$ for shipping. I have ordered about 6 earphones from Dealextreme, each 3-5$, most of them from Kanen (formerly Kanen, they changed their name) [Exact Product namers: EC1, MD-71, EC7], all of them are inferior to MD-52, so don't waste your money on them. Though the EC models have a very pleasant cable clothing (?), see this photo on DX
The MD-52 have really great sound, (Sayajin says in his review they have about the same SQ as SoundMagic PL-30) there is nothing I could complain about. I even use them as speakers when I am in a quiet room; even at Meizu M6 volume 40 they have no loss in quality, compared to the distorted sound of all other earphones in this price category when you turn the volume up.
I have to say that I have never listened to real high-end earphones; the most expensive being 40€ AKG K324P which I found to be worse than Kanen MD-52.
However, if you are looking for Earphones below 12$, this is probably the best choice. There have been some reports on faulty ones, up to 50% per order.
If you want to spend a bit more $, go for this site
They have Sennheiser CX300 (confirmed to be original and not fakes; they are said to be about the sq of Kanen MD-52, but I can't approve of this) for mere 18$. Atm, they are out of stock though, dunno when thy will get more.
I would by the SoundMagic from mp4nation.net and not from focalprize.
