Intro   GR07, Vsonic's statement in the IEM world. Featuring a Sony-licensed 11mm bio-cellulose driver, it was unlike anything out in the market. IEM's have come and gone, upon release many get hyped and overrated, but loose their sparkle over time. GR07 has proven to be able to withstand time, because it is simply a great product. At this time, despite the VC1000, GR07 is still considered the flagship product and has been mentioned to be the most proud achievement by Vsonic's CEO [interview linked on the bottom].

   Intro This is an IEM that caught Head-fi by storm. Featuring a single 10mm high-bandwidth dynamic, using two patented technologies, Ostry made quite the statement.

But it's...

  Introduction      Having had extensive experience with the previous Wood series of JVC, FX500 and FX700, I was exited to see what the company had planned for this next iteration. They introduced FX650 to replace the FX500 and FX750 to replace the FX700, in addition to announcing the new flagship, FX850. Thanks to user James444, I was able to hear all 3 IEMs of this new series, while still having in possession an FX500.
