I just had the GR07s for a week and I thought I'd share some of my thoughts. I tested them with a Zune, my work computer, a Fiio X3, and a Fiio e11. And my comparison is to sr80s.
- They're not as bright as my Grado SR80s so they sounded more subtle as I listened to them driven through the Fiio X3
- I liked the fit better if they were
looped around my ears or
worn normally and swapped so that the left monitor went in the right ear. Both pictures borrowed from Head Fi.
- I think I preferred them driven through the e11 versus the X3. The X3 was very warm but I felt like the sound was too subtle or muted. The e11 seemed brighter.
- I really appreciated the difference between the amps that I tried for the first time.
- I really wished the cable was longer.
- I thought like the Grados, the GR07s aren't as good for music styles like hip hop or electronic music. It sounded amazing with metal and classical music though.
I really enjoyed the Vsonic GR07s, to the point that I want to get VS1DS IEMs. I hope that I get more exposure to audio equipment. I'm a little out of my comfort zone trying to write a review on IEMs and cans but I really enjoy getting into this.
