IIRC they originally sourced the membrane of the dd from Japan, then switched to their own. But no difference to the user.

That's what a bunch of people assumed, but it's the same driver.

Last year there were discussions regarding whether GR07 Classic still used bio cellouse diaphragms. In the end, Vsonic's CEO confirmed the rumours were false and they are using the same material on GR07 Classic.
 
It was logged here below, though the misunderstanding still hangs around to some degree.

That's true. The dd membrane is slightly different but I think most agree the sound is identical - mark II vs. classic. I only have the classic.

It's not different. It's exactly the same as confirmed by VSonic's CEO.

Same exact drivers as the original. Thanks for the correction!

Does anyone have ideas for calming the GR07's sibilance?
 
I'm experimenting with equalizer settings. My initial strategy has been to take off 4dB at 6000Hz and leave everything else flat. It's helping, but I'm going to keep fiddling with it. I'm curious what settings and tactics you guys use to tackle sibilance.

See the tips thread. Other than that, you may want to try a different IEM.

To tame the sibilance you need to use tips that are long and smaller bore. But at the same time, not too long, which will kill the high treble or too small of a bore which will kill the midhighs.
 
M6 biflanges seem like a good option, I'll do a lot of tip experimentation with these soon and see what I can come up with for sibilance, the trick is to tame it without messing the other parts of the treble too much.

Sony MH1 tips are another great option for taming the sibilance. It also brings out the mids.

Burn in, at least 150h and good fit.

I've been spending so much time with GR07 MK2 recently its not even funny anymore. Let this be a word of advice on how versatile, high performing GR07 can be. I don't know how others feel about amping GR07, I mean, I can listen to them from  Sansa Clip, Cowon J3, Colorfly C3 and they sound really great. When I pair them with my JDS C421 amp / DX50, I have been constantly surprised at the performance levels. At one stage I was listening to GR07 exclusively for about 3 days, when I switched back to Fidue A83, RDB Mini, Altone200 each one of them sounded completely wrong, like the balanced armatures made the music sound fake, thin, off. Of course, this does go away if you allow an adjustment period, but without allowing time to adjust there was more than a few occasions I put those other hybrids down going back to GR07. I even had thoughts of just quitting buying anymore and sticking with them.  This is still continuing today, I wonder how much longer...

My MKIs still put a smile on my face. Honestly im considering a pair of classics as backups incase they decide to close up shop on the GR07 sometime. They are easily one of the best buys i have ever encountered on headfi. I have tried armatures and found them to lack body and a the natural sound of a dynamic iem.

I'd like to hear the Classic one day myself to experience any differences. And you're right, the note weight on most of those hybrids appear off / thin. Of course, I must confirm, once I adjust my preference swings back (which is balanced armature sound) but another thing I found is, GR07 is easily listening for long sessions. The A83 is like an extreme roller coaster ride, they sound great and they do this playing loud, always inviting me to push them up a notch and then another, I could not listen to them for hours due to this. In the end longevity and genre versatility are powerful features of GR07.

Just ordered the Classics from Headphone Bar.  Looking forward to trying these!

Congrats! They are amazing IEM's!

Still pop in my gr07s while commuting and ,while my new Fidue a83s do see more ear time at home, my gr07s will always be remembered as my intro into good sound quality.

Will get a chance to compare the Bass Edition to the Classic, in addition to a modding idea I have in mind. I will let you guys know how it goes as soon as I get the chance to do this comparison.
