To help those out still trying to buy this at a good price try
http://www.mobimega.com/sony-mh1c-smart-headset-with-smartkey-control.html . its shipped from HK and i just got mine from them. its genuine and everything looks good. Its in bulk packing so no manual or box but still nicely packaged.
My first impressions after having using GR07 for two months as my first higher end IEM.
Bass: Good quantity, and good impact awsome for hip-hop rap or any kind of electronica music. A bit much for my taste for anything with band music or orchestral. The quality of the bass is not as good as the GR07 but it is still very decent.
Mids: nothing too outstanding , good but not as clear as GR07 on first impression
Highs: First impression is good because it made me realize that GR07 is actually very siblant while MH1C was not at all even when i boosted the treble for the extra sparkle and clarity! But i would say overall GR07 does highs better except for the being siblant part.
the ear tips are 'bouncier' than the GR07 stock ones so they fit tighter and thus result in more pressure in my ear, but nothing that makes it uncomfortable, just feels different.
The sound stage for me was noticeably bigger and wider than the GR07 but not by very much. Separation was on par with Gr07 but i would say GR07 edges out being a bit better on this end.
overall MH1C is a good purchase and worth a try, the only down side is that while i adjusted to the J cord it is still annoying, stiff, bouncy, and rubbery.
