Comparisons to be finished
OK! I now have the following to go...
- FXD80 vs EPH-100 (2-3 days)
- A161P vs PFE vs XCape v1 vs HF2 (may take a week, hope @psygeist is ok with this)
- Pro Alpha vs E10M
- SM3 vs FI-BA-SB
- FX700 vs FXT90 vs FXD80 vs FXD70 (Probably 3rd / 4th week of August)
I
may have another one coming. If it comes as expected, I'll have to push back everything by a week
JVC HA-FXD80
Both FXD70 and FXD80 have completed their mandatory, magical period of 100 hour burn-in including few hours of higher volume burn-in. When they were burning in and I briefly compared them, without even inserting them fully, I preferred FXD70. I highly suspect it still might be the case.
I am not sure, but my FXD80 requires higher volume than most. It's been ages since I've pumped volume above -30 in Clip+. But, for the 80, I need to keep it at -28 to -26 depending on the recording. It requires higher volume level than most even with powerful player like QA350 or UHA-6S. May be I'll try a louder volume overnight burn-in again and see how it goes. I even suspected if mine is a lemon, but when I ran a frequency sweep (with stock tips) and checked it against Sonove's graph, it seemed alright. A dip from 4-5, BIG spike at 9Khz etc.,
The signature is dependent on the tip used and the depth of insertion. I have so far tried the stock tip, EPH-100 tip, Monster foam and am currently on de-cored Shure Olives alternating between shallow insertion and normal insertion. There is driver flex on the left with stock tip and in both ears with EPH-100 and Monster tips, but none with Shure so far.
Two things that stand out about FXD80 - clarity and imaging. One thing that I don't get about FXD80 - I hear grain / distortion in the mids at times. Overall, I'd say it is a balanced sounding IEM, but with a treble tilt.
With the Monster tip and the Shure Olive, the bass sounds fairly tight. The mid-bass quantity, unlike the traditional JVC sound may be even less than EPH-100. When I was burning in with stock tips, the bass quantity was much higher. The mid range is at a slight distance. It is clean, clear, crisp sounding. But, there is sibilance with both the foam tips - Shure and Monster. I did not try enough with stock tip and do not remember this much with EPH-100 tips. The treble is forward, sparkling and has a big spike at 9Khz. It is somewhat controlled with both the foam tips compared to stock tips, but the quantity of treble still does not escape attention. The quality of treble gets a bit lost with Shure foam as it cuts off a bit of extension. I will experiment more with tips and angle of insertion and see if I can find something that can make FXD80 great sounding to my ears. At this time, I can hear a slight resemblance to the JVC family sound, but I'd say that
at this stage, it sounds more like a decent to good IEM than something that is a giant killer. Of course, comparisons will decide where I'll eventually place them.
