    Dear all,

    A couple of months ago I discovered this new JVC (Japan only so far) iem, and given JVC's track record with dynamic drivers, this seems quite promising.


    This iem, like the FW01, is the top of a line with lower end 02 and 03 models.

    It carries a 11mm "D3" dynamic driver with a "diamond like carbon diaphragm", a moving air damper and a Titanium casing.


    Beyond the technical mumbo jumbo, it has a few interesting characteristics. It uses MMCX connectors, and also has a 360 degree rotating nozzle for optimal whether your wear it up or down.


    Finally, it allows to change the inner nozzle between three materials : Titanium, Brass and Stainless Steel, to adjust tonality.


    More info (in Japanese on the JVC website).

    I might get a pair soon unless JVC is reading this and sends me one for free...


    Below find some (Google translated) specs :

    Wow, the nozzles of different metals is an interesting feature. Here's hoping to see some impressions on these soon.

    Any idea of the price?
  5. Roscoeiii
    Nevermind, found the price: 43,070円 which is approx $380 USD.

    Even more intriguing...

    How much of a change are the different nozzles really gonna make? Is it ONLY the metal that's different?

    Um, your pic is the FD02 and not the FD01. :ksc75smile:
  8. mochill
    Probably will get these in the future

    Honesty no idea at this stage. It seems it is only the material.

    Wow you zoomed :D updated.

    Just a short summary of difference I found between 01/02:
    -FD01 has interchangeable nozzles , 02 doesn't
    -FD 01 has a isolated L/R cable, 02 doesn't
    -FD01 has a titanium driver case, the one for 02 is made of stainless steel

    Spec-wise they are identical. Personally I am interested in FD02 and LZ A5 lately.

    So the most important difference is titanium driver case and stainless steel and i read i FW01 thread that the FD01 sounds more refine than the FD02 because of that difference ,

    These look really interesting and I am intrigued to try them. My only complaint about the FW01 was that 90% of my MMCX cables didn't work. It was as if the connector was slightly different and most of the MMCX cables I had would not insert all the way. Anyone else have that problem on JVC? I don't remember that on my FX1200 by memory, but that was long before I was a cable-hoarder :)

    Seems that way to me as well after reading the translation via Chrome. It's possible that things could change with burn-in at the 300hr mark, but for now he recommends the FW01.
