Ok- so out of the box impressions are extremely positive. I settled for the blue tips without the foam. Playing Bob Marley Pandora station (with Pandora One) on my iPhone 4S and vocals are in line with the treble instruments in terms of volume and the bass is present but not overwhelming. Playing Today's Hits Radio makes listening to pop/hip hop songs engaging. The Script Radio and Gun's N Roses Radio were enjoyable. I agree with statement that the GR07 BE is a great choice for all sorts of music genre. I think I made the right choice in the Bass Edition because I find the bass amount perfect for my taste. And I may be annoyed if the treble were any more.
DISCLAIMER: I'm a novice at describing what I hear into words. I have pretty good hearing, but audio vocabulary is weak. In support of throwing out terms, I will explain what I hear so that if I do use the wrong term, you know what I am talking about. Thanks.
Compared to my burned in VSD1, I can sense the VSD1 to be warmer/fuller in the mid bass region. The GR07 is airier- I can sense some space between me and the music. The GR07 is quicker, smoother, brighter. VSD1 isn't bad for its price, but the GR07 is more refined (just as it should be for its asking price).
The GR07 has perfect musical energy, where my XBA-4iP is too much in the upper and lower frequency and my PFE 132 (grey filter) is too vanilla (little rumble and crispness). The only thing they have on the GR07 is their mic and call/music controls.
I can sense the upper frequencies are ever so slightly rough- I think this is due to the driver being brand new.
I would be a happy camper if the only change of burn in is the smoothing out of the treble- even with the current amount of bass.
