Alphahelix... I like the fact you totally over looked the link i posted you. You will be suprised if you actually read it at all. The GR07 is a monitor iem, so if you are after a a flat sound with good bass then take a look. They wont cost you an arm and a leg, the build quality is great for a lower priced IEM. If you dont believe me take a look at what ClieOS had to say in his review thread. I have owned both the IE8 and SE530 and "I Feel" these have a better overall sound then both of them. http://www.head-fi.org/forum/thread/541204/concise-multi-iem-comparison-meelec-m16-m21-m31-sp51-added-april-2nd-2011
Also take a look at http://www.j-phonic.com/ they might fit your bill aswell. There is a couple of small writeups about them on Head-Fi, the customisation is pretty cool. Being able to pick your cable length and colour etc.
