Since this IEM is about to be released, I decided to create a dedicated thread for it, as something tells me that this thread will soon be very "busy"...
Regarding the specs, not much is known yet, but the driver configuration is triple hybrid (dynamic driver with a dual/twin BA). It will feature a detachable cable and brass housing (for the metal part). The price is not set yet, but it's expected to be around 250~300 USD (and maybe an "Head-Fi user" discount will be available, like what happened with the H-100), and they're supposed to start selling by next month, January 2013.
Their sound, compared to the H-100, was described by the manufacturer as being a more balanced sound with fuller mids, softer treble and great soundstage, improving those areas over the H-100's. Reading that, and as I own the H-100, I'm expecting great things from these new H-200!
Here are some pictures of the prototype unit (thanks to user Raphael K):
It seems that the sound tuning process is finalized, but they're still looking into some details about the detachable cable. If everything goes according to plan, they should be releasing it early next month. Here's the latest picture available, where you can see the cable connected to the housing (but the cable and connection may still be changed):
And another one (in b&w):
It seems that they'll only be available by the end of next month (February) due to some components and package constraints (it's not a final ETA, though)...
*** UPDATE: NEW CABLE CONNECTION DESIGN ***
I can now share some more info about the new H-200. There are some H-200 units about to be shipped to a few reviewers, so you can expect some reviews out soon!
The retail price for this triple hybrid model is also set, $250 shipped by EMS! Even better than this, there will be an Head-Fi special deal (as with the H-100 model), limited to 100 units with a special price of $200 shipped by EMS! Orders will be accepted from April 14 and will start shipping from April 25 (this is what's planned). More info will be officially available from T-PEOS soon...
