The Earphones are so good you can really feel the bass, i am a hearphone maniac and i have loads of different earphones of all different ranges, some people are really bothered about earphone range but you got to remember the human ear can only hear around 10hz-20khz so this beats that by miles, so your headphones (if you have these) wont just be blasting out good tunes but also notes you cant hear...witch is really cool he he !
The quality of the build is great! you can really feel the 50mm driver, the bass kicks you in the face (in a good way)
The postage came very quick
The only thing i found a problem was it took my about 10 mins just to open the plastic packaging to get to the earphones but it wasnt that hard ;)
overall if your looking to get these headphones i say get them, your missing out of you dont, you wont find headphones this good for the same price! :D
ALSO: The look of them is rugged and very hardcore ;)
