Since this is an appreciation thread, here's mine:
It's an awesome pair. The only way I can stand my M1s now that I have the GR07 is to listen to a really shitty pair just before I put on the M1s, otherwise they annoy me. Don't get me wrong, the M1s are very, very good. But the GR07 are just... well, let's just say my search is over. I've found the sound that really suits me, in a comfortable package that looks like it'll last a while.
A bit of sibilance/harshness at the beginning, went away after maybe 10 hours. They're smooth as butter now.
Haven't heard anything BA except the ER4S (which I didn't like because of comfort issues), and that was a long time ago so I don't know how they compare in clarity, but the GR07 are certainly much more user-friendly. Even the stock silicone tips are perfectly all right to me.
Anyhow, I think they rock. Good balance, good build quality, just colored enough to be fun, good soundstage, good comfort, good versatility with different genres. Others may have slightly better sound, but I haven't found something which was so good in all aspects at the same time at that price point.
Hope they get stocked at lendmeurears soon so more people can get those. VSonic deserves to sell tons of those.
Huge thanks go to ClieOS for writing the initial review. Would never have chanced them otherwise (actually, wouldn't even have known about them!) and I'd probably would have gotten a DBA-02, waited for months to get it, and then spent several weeks trying to get the fit right :)
