Ya we are just understanding what these newer JVC cheapos are doing for us. I haven't tried any new tips myself but I will experiment. Agreed these need the best seal.jpg possible.!!

I own the FX67 and the FXC51 for older JVC cheapos. Both are excellent. Never tried the marshmallows but I can tell you there is no possible way those are gonna sound better than these newer JVC earphones. JVC is charging the same amount but are giving us a leap in sound.  I would skip the older stuff and go straight to the goods.

In the spirit of discovery I just ordered these for around $49 shipped...

Taking this thread on a small detour from Japan to Korea :) Actually I'll just make a short post here to update and start a thread for them assuming they deserve it(they should).

That's interesting they are using sub chambers like the ones used for ATs CKS earphones. Interesting. look forward to your take on them Jant. Those should have a nice spacious sound me thinks.

post #1579 of 32866

Not to put thoughts in anyone's head but Cresyn has made earphones for AT in the past.

 

They look similar to the PS20 which Cresyn also make under their Phiaton brand but change the back and open them up. Great if they are even better than the PS20 and cheaper but this is what is supposed to happen just like a new, cheaper CKM phone sounds better than a previous, more expensive one :)

Couldn't help it. We are both in NY. You were bound to hone in on my thought patterns since we are so close. Though, Dsnuts actually formed the original thought pattern in post #1578.

So here I am. Couldn't sleep at 2:00 AM. Got my FX40 in the ear listening to some Frank Sinatra of all music. Lol! Good ole blue eyes never sounded better. It amazes me just how good these sound..As impressed as I was when I first heard these.  These to me now sound simply wonderful.. I will say it again, do not judge these out of the box so much. I am fixed in my mind that all JVC earphones need burn more than most.

 

The sound can still use more depth but the clarity and resolution in the sound is undeniable. These keep growing on me every time I hear them..I hope you guys give these a fair shake before ruling them off as another decent cheapo. I would leave them playing music for at least a week straight before listening to them.  The highs have completely tamed for me and now sound great on these and the biggest change has to be the mids. It has officially caught up to the highs. The sound is so much more balanced from open box. These are cleaning up here and there from the aggressive burn I have been doing.. I know some might worry about an aggressive burn or music too loud on these to burn them but these drivers can take the punishment.

 

I don't know about 10/10 loudness but a good 7/10 should be just fine. I still wonder if more burn is needed so I will keep them burning for at least another 100 hours of burn to see if any more changes happen. The FX101 has been on the burn as well and I will check those soon to see where those are going..Will update on those next.

My FX40 is still being burned in. You are so right about needed so much burn in. The sound problems I initially encountered with this are slowly fading away. This is a great deal for the price, but I still want more. When will we see carbon nanotube IEMs with larger drivers? This one has just 8.5mm drivers. I guess with larger drivers would come higher efficiency(this is just 101 db/mw) and perhaps even more detail.

My FX40s now have about a week of break-in. They are significantly improved in the midrange, bass doesn't seem to have changed much (which is fine). I still have some issues with the upper midrange and treble, but it seems to depend on what device I have them plugged into. That part of the spectrum is still too damn hot when listening through an Audioengine D1 at home, and to fix it I've had to employ some EQ in foobar to drop 1-2 dB out of the 3.5 to 12 kHz region. The worst of it seems to center around 5-7 kHz. Perhaps even more burn in will help, but these have something like 120 hours on them by now. On the same DAC/amp I detect just a touch of unnatural boom in the bass, fixed by dropping 1 dB from 77 Hz and below. Even after that, I can listen to Speak to Me (first track on DSOTM) and it still sounds like my heart is going to pound out of my chest, so there is plenty of bass in these.

 

The sibilance is not an issue at all when playing straight out of the headphone jack on my ipod, without running any EQ in rockbox. Midrange is good too, but of course you don't get nearly the same bass impact without an amp. When I add my Fiio E11 amp, the bass impact comes back, midrange is great, and the treble keeps its clarity and resolution but doesn't have any of the harshness that it does on my home setup. Bottom line, and I haven't really noticed this with any of my other dsnuts approved IEMs, but it seems that these FX40s in particular don't play well with my D1. But they sound great on my portable setup, which is really what I intend to use them for.

 

I ordered the FX101s from Amazon a couple days ago, and to my pleasant surprise I had some gift card credit I had forgotten about, so I will be getting those basically for free. I also found a $5 bill laying on the ground in the parking lot the other day. It's raining money up in hurrrrrrr.

 

5 weeks after ordering, I finally received my package from focalprice that has the CX-700s and some Sony EX-300 (presumably) knockoffs among other things. Preliminary impressions of the CX-700 are very good, got a set of those burning in at home. My pace of purchasing is faster than my ability to give each earphone a thorough burn-in and evaluation. I have a lot of listening to do.

Great take on the FX40 Scott. I agree that these were intended for DAPs. I play mine though my Sony S545 and the synergy is about as good as it gets with this combo. They sound great on my cell phones and my Z1060 as well. But something about these with my old Sony player. It is a match that is hard to separate.

 

You have become quite the budget connoisseur. Lol. Enjoy your new earphones and give us and update on them when you get a chance. Great to have you on the threads my friend.

I now have the Phillips SHE3580. The sound is pretty awesome for the price, but it gives atrocious feedback noise withe the slightest twist of the jack. Is this universal or just me? It really crushes the audio goodness.

Your perception of the microphonics are correct. They do have some bad microphonics. You can wear them over your ears and that helps reduce cord noise. The good news is I don't know if you ended up ordering these JVCs but both the FX40 and the FX101 are almost cord noise free.

post #1588 of 32866

Just a quick update on the FX40. Trying them out with my Digizoid ZO2 today.

All I can say is that I these headphones continue to impress. No other headphones I've used scale up in bass as well as these do. Every other headphone (including MMDTs) begins to distort or get muddy when the I start to push the bass into the "yellow" on the ZO. These I can comfortably get into the orange and even the red without distortion or muddiness. 

On the way up to full bass (red on the ZO) the amount of bass added starts to taper off. It's like the carbon nanotube design has some natural attenuation to it that prevents the driver from extending past its limits into distortion. 

 

So impressive. If the FX80 has this same quality but can add more soundstage and air, it will be a giant.

One other note. I did find one fault with the HA-FX40s yesterday. After some extended wearing I found out the fit starts making my left ear hurt around the 60 minute mark. :(

I just use bass boost on my Sony dap and it has plenty of bass for me. Agreed on the new JVCs I can't wait to try those out but I hope the cost will be reasonable.

 

I was thinking if you use bi flange tips I bet the housing won't even need to be in the ear. Maybe a bigger comply tip? You know come to think of it I will try that. Will report back .

 

This works and sounds great. bjaardker. Try this. The housing is no longer in my ears using these comply foamies and the sound is not compromised more comfy to boot. 052312115307.jpg
