The FRD is with mic, for smartphone use.  I have both, generally they sound the same, the FRD is slightly more V shape in tonal balance compared to FXD.

How should I go about burning these three in? I've never burned in any earbuds before, any tips? Also the FXD 80s don't leak much noise right? I know they're sort of open but...

 

Congrats!  Despite of other more expensive earphones I have, FXD80 is my favorite!

FXD80 improves with burn-in.  I use regular songs, I take only one channel of the song using Audacity, so I burn-in with mono track, so left and right driver get equal treatment.  I have 2 FXD80, so I did some experiment before, burn-in one pair for 4 days, leave the other pair as new pair.

After 4 days burn-in, the pair sounds a tad smoother, and the most discernible improvement is the spaciousness.  The burnt-in pair sound more spacious, better depth, more open, with clearer instruments separation. It gives the impression that it is more relax sounding.
The difference was not night and day, but discernible.

oh wow that answers MY QUESTION haha but how did you find the driver flex between the two? is one considerable worse over the other? everything looks amazing so thats what concerning me

 

is the bass more in quantity? in the midbass, subbass?

The different between XFD and XRD is not night and day, basically still the same sound signature on both.  It is just the FRD is a tad more analytical, a bit more treble, and the midrange a tad recessed compared to FXD, that's why FRD sounds a bit more V shape compared to FXD.  If sound quality is my utmost concern, I choose FXD, overall more natural tonal balance.  I ordered both FXD from Amazon, the seller was Comtachi.  FRD I bought from local shop.

 

Bass level is about the same, full and powerful, without any exaggeration, still in natural level, but to me, better than Vsonic GR07 Bass Edition.  Both FRD and FXD bass extends very low, rich low bass harmonic.  Bass is just excellent on both.

 

FRD and FXD are suppose to share the same driver, why they sound a tad different?  I don't know, as it is also my question to JVC :)

thanks for the reply, did you find a difference in driver flex? it seems like i would probably be happy with either or to be perfectly honest haha

 

i have driver flex in my monster turbines (fully sealed enclosure) so i would think the driver flex would have more long term damage > the fxd 80s which is semi vented

 

however i'm not entirely sure the effects of "driver flex" all i know as it when i inserted it sounds like the drivers might be getting damaged lol who knows if it actually is getting damaged though

What do you mean by "driver flex" ?

apparently its a known issue among the fxd 80s its when you insert it into your ears, you hear a crinkling in the driver diaphragm due to the pressure changes upon insertion

 

apparently what I HEARD  is that this can have a long term dmg on the drivers specifically fully closed iems like the turbines because the air would have no place to go i would imagine.

 

but for a semi vented housing like the fxd 80 the air would be able to escape i would think so if my logic is correct it shouldnt be as bad

 

but this is just all speculation soo i dunno any other fxd 80 owners want to chime in?

I didn't experience any driver flex with all FXD 80 I use and tested (so far tested 4 of them, I have 2 myself), and also none with my FRD 80.

thats crazy lucky then lol! to have all 4 with no driver flex did they fix this issues on the later releases??!!

Sorry i think i made wrong statement and misunderstood your explanation of driver flex.
If what you mean by driver flex is the kind of creaking noise like when you creasing a plastic sheet, yes, my FXD80 and FRD80 all have that issue during insertion to the ear canal.

It didn't get my attention before, until you mentioned that it is driver flex.

No driver flex in my case.
On a general note, I doubt it has much to do with driver design so that it can be "fixed". Rather it's a function of tips used, ear canals, insertion technique etc. A driver that is supposed to reproduce sounds in the full audio band has to have a flexible membrane, period.

interesting thought, this might sound like a stupid question then, but how do u insert them into your ears? or the tips you used the jvc needs a really wide bore from what i can remember cause of the micro driver

 

i obviously dunno your ear canal shape so i figured maybe if ur method reduces driver flex i could try it for my turbines

post #1661 of 1852

Frankly I do not pay much attention to the insertion, I rarely have driver flex issues with any IEMs. If this is such a problem in your case, try to"postpone" the creation of the seal towards the end of the insertion. The flex occurs because of the driver having to support the increased pressure while advancing in your ear canal: the less advancement after the seal occurs, the less pressure is applied on the driver.

 

You can try to open your mouth during insert (like when yawning), this should modify the shape of your canals and slightly enlarge them. And/or you could also press the IEMs gradually, with rotating moves back and forth.

 

Tips can make a difference too (the ones that are better at creating a seal in your ears should be more susceptible to cause a stronger flex), but this is hardly an issue in my case. I've tried the FXD70/80 with many tips (including the original ones) and did not make any difference to me from a flex perspective.

JVC FXD70 is the only headphones/in-ears I have two pairs of. That can perhaps be the biggest praise I can give.

After over a year of use I thought it would be a true shame if my pair died and the model discontinued so I bought another one.

Comparing the two I can tell the newer one that have perhaps 30 hour of use is more trebly and harsher and do not sound as open. Can be lack of burn in or just variation within the model.

Let's see if they sound different with 200 hours of use.

FXD 80 arrived, listened to some music off my Lumia 920 last night before bed, and right now on my Surface Pro. I am so happy, sounds really great, build quality is insanely good, cable management is good, might get some aftermarket ear tips but overall this is the best pair of earbuds I've ever had!

lemme know what tips you use! these have a really wide bore and i think finding aftermarket (wide bore nozzles) to be difficult.

 

do the stock ones have a narrow nozzle? or wide nozzle? 

 

cause obviously the width of the nozzle amongst other things can tweak the sound

The bore is pretty wide, but it works well with the smallest tip that came with it, might try out aftermarket tips later, but for now it's perfectly serviceable.

I just love the sound, these fit my uses very well, and the cable is great and it has the little cable thing that slides up to keep cable management easy, definitely something I liked on my Sony XB60EX and that I miss on the XBA1s...
