I recently got SP51 which I ordered from the official site ( with 55% coupon discount $27 + $4 shipping costs to my country = $31 total). These are my first IEMs. I'm very glad that customer service allowed me to order from their site because my country wasn't on their shipping list. Amazon doesn't ship to my country either.
I bought SP51 because it was the best deal among all MEE earphones at the moment. I think that the build quality is decent. Sound has a lot of bass. I liked the metallic port more ( out of the box they came with the black port on them). The black one is too boomy and strains my ears while the silver one is a bit lacking in bass. The mids and highs are just OK which makes you want to try something clearer or more balanced.
These are definitely better sounding than my cheap earbuds. I enjoy my music much more.
