the 4 pro is better
but the 6 has a richer, warmer sound that many may prefer
how about for female vocals? I listen to female vocals (country-pop), so I would like IEMs that shine in vocals...
I have it already... but I don't think it's that good. it's a bit too overpowering for me.
I don't have original GR07 but the MKII is pretty good for female vocals, better than the ex800 or xba-40. The midrange emphasis on GR06 makes some singer sounds older. It doesn't makes much sense to compare 06 to 07 as the price is only 1/3.
Also it seems that some posts were deleted.
