The GR07 still is such a fantastic sounding piece of kit. The driver, the design and the ergonomics just come together to form such a great product. I recently tried the new VSD3S, and while very good for the price, there is no comparison to the GR07.
I hope that Vsonic are still working on stuff behind the scenes. Whatever they release as a potential follow-up to the GR07, I will buy it. I hope that they try to avoid the sharp treble of recent releases, including the VSD5, VSD2 and VSD3S. I would guess they share the same 10mm driver which might explain the similar treble sound. Of those I actually prefer the VSD2 over the VSD3 and VSD5, because my VSD2 isn't as agressive and I can bring the volume up to more pleasing levels. The VSD5 has a much more agressive, though richer, more even treble, but the VSD2 treble still has good definition and sounds quite natural apart from some high treble focus. The New VSD3S I'm underwhelmed by after some listening. There is some peaks in the high treble I just cannot adjust to, it sounds crystalline like the VSD2 treble, but it's also sharper and more agressive like the VSD5, so it quickly becomes tiresome.
