Nope, I own JVC FXC51, JVC FX500, JVC FXD80.  I've tried the JVC FXT-90.  I also own the JVC HA-S500 (headphone).
 
The impressions of the FXD70 seem good in that it may have the better FR, mids etc., but tomscy2000 said something like it's less airy or more closed-in sounding, which makes sense since it's not vented like the FXD80, so I skipped it.
 
Then again, I don't think the JVC FXC51 is vented, and despite it's flaws I quite loved that IEM too!  Only after using an equalizer and pretty much only with psytrance music, though.
 
I remember back when user "Katun" was saying it's better than the Ultrasone Pro 900 after eq, and all kinds of comments like that, I picked it up and found it was really good after eq too, fun times before the FXD80 existed.

Ok, thanks. I have the 70's, and now that I got my R1's foam tips on them, they sound quite great to me (the foam tips help me get a deeper insertion, and they dampen the highs and bring out a bit of bass). Having said that, the xba-3 is the iem that I will never be selling (which tells you how much I think of them!).

As for the JVC IEM's, try them over-ear with a deeper insertion, it really improves the spatial presentation IME.  For me personally, the JVC FXD80 is one IEM I'll never sell.

It's not for fixing inverted polarity.  It's for fixing the errors you receive when you use too many drivers at once.  Show me how to implement freqphase on a single driver IEM?  You can't.  Please try reading this and expanding your limitations in acoustic audio -> http://www.kef.com/html/en/innovation/uni-q/index.html
 
The JVC FXD series have very high unity, singularity, Q, whatever you want to call it.  Something the XBA-3 does not have, I don't think the CSD waterfall gives any indication of this kind of time error either, since it's sortof 'within' the IR envelope itself.

No big difference with deep insertion, bass still too bloated and treble is too sharp, not to mention recessed midrange.

We have established the JVC FXD series has heavy bass and sharp treble, it's not a studio monitor IEM.  It's a Hi-Fi IEM, watch a movie on the FXD, you'll have a hell of a lot more fun than the Etymotic HF5.  This could be easily established, statistically, with a survey.
 
The deep insertion doesn't improve FR, it improves soundspace and imaging.

That's true that music is about hearing but at the same time you acknowledge errors when using too many drivers at once. These errors are the reason customs aren't as accurate as single drivers unless the customs themselves are using a single driver. Are you saying that deficiencies that are visible on measurements are not audible? Do you have a example of one? I'm genuinely interested.

I think the FXD80 succeeds at what it is, a colored iem with a lot of treble and bass. They are emphasized but clear and well executed. Honestly they were my favorite sound until I heard the sr009, lcd-3 and hd800, which totally redirected my audio preferences towards neutral.

I completely agree that the fxd80 is amazing for movies, and if I ever used iems for movies I would have never sold mine.

Funny cause I heard them all at my local Sony store and have yet to see a graph of the XBA2. Of course it's all listening, that last remark is just plain silly.

It fixes polarity issues, thus allowing the drivers to be more in time with each other.

It does change the soundstage but not the imaging

I actually EQ small things, like adding bass to the RE272 and tame the EX1000s midhigh spike.
Irrelevant again as I'm speaking of the app, not EQ in general.

The FXDs can be harsh for movies as well IMO, rather take a smoother tone though the boosted bass is nicer for movies. Still I listen to mostly music, not movies.

Hey, Kiteki. Have you done comparisons between the fxd80/fx500 yet?
If you haven't already, care to give me a brief run down on bass and highs between the 2, please
 
Still waiting for fx700s at a good price to pop up, so till then... these might be a nice addition me thinks.

I don't mean all custom IEM's, more specifically I preferred the JH11 to the JH16.
 
Theoretically you can use as many drivers as you like, as long as the crossover technology can handle it (which most of the time, it doesn't).
 
 
Of course deficiencies in measurements are not necessarily perceptive deficiencies, have a look at the Qualia 010 measurements, yet it's one of the most respected full-size HP's, as an example.  I use it's cousin the SA3000 which is one of the most overlooked HP's ever, in my view.
 
The LCD-2 / -3 and SR-009 may excel with neutral FR, however they excel with a lot more than that too, since they are planar-magnetic and electrostatic.  The HD800 is extremely open-air (like a STAX), which improves it's presentation too.
 
Yup it's amazing at what it does.  It's an excellent V-shaped IEM, and the CNT, plus the driver in the tip of the nozzle are very unique.

Ok thanks, at least you concede to that.  Well the unique soundstage of the FXD series is the best feature which sets them apart from say FXT-90, in my view.

The bass is also tight and high quality, unlike in the JVC S500.  The treble spike makes details in movies more present and exciting.  Yeah, preference plays a part, I just think it's an amazing IEM with action movies.

I suspected it was either making the drivers more in time with eachother, or it was using a digital DSP for very sharp crossovers, like in the diyaudio link I posted on active studio monitors.

Yeah that sounds like the correct use for EQ, little adjustments like that.
 
I don't see what's wrong with the app, I guess I'll wait for the review...
 
It's about parametrically equalizing all IEM's to sound 'the same', from the same reference point, with very advanced measuring equipment.  It should be a fun test at least.

You already know what I think of the FXD80, here you can read what I think of the FX500 -> http://www.head-fi.org/t/614513/jvc-fx500-yellow-filter-black-filter-and-cotton-removal-review
 
 
I don't know, the FXD80 is a Japanese sushi knife at a theme park, the FX500 is a very narrow concert hall.

Hey guys, please tell me, what do you think of this song on the FXD80?  What's the overall quality of the sub-bass, vocals and clarity like, versus all the full-sized headphones you know?

Maybe I'm not allowed to play because I'm not using the 80's or a full sized can, so my apologies in advance...

fxd70 (with R1 foam tips): very nice, detailed sound, vocals present, not really much in the way of sub-bass.

xba3 (with light blue non-hybrid tips): very nice, detailed sound, vocals present plus nice sub-bass, nice soundstage, nice imaging, nice depth.

s500 (with ath pleathers and vents taped): like xba3 but with a lot of sub-bass

FXD70, not much sub-bass?  I find the sub-bass insane on that track with FXD80.  I realised it knocks my ATH-ES10 out of the water.
