Result: I couldn't detect any significant difference in sound quality. In a nutshell, the FX850 sound the same with six different cables I've tried.

For whatever reason, i do not hear these as bassy as others do. Almost sounds flat in the bass. If not slightly elevated...

Depends on what you're coming from. The FX850 in stock form has got a crazy mid bass hump. I love these phones when modded though.

Hard to describe such subtle changes that happen over time, but they did. I doubt you'd be able to measure these changes in the FR though, but what do I know.

And of course there's still the age old disussion of driver burn in versus brain burn in, but personally I don't believe they have to be mutually exclusive.

Funny story about that.. I let a friend hear the 750's pretty much out of the box. He loved them but thought the bass was too overwhelming. Months later, in which I had used them every day for about 4 hours, so enough time for the drivers to burn in and my ears / brain getting used to the sound, I let him listen again. Without me saying anything about the sound, the first thing he noticed was how much the bass had settled down and the sound as a whole had become better. He was noticably surprised, saying "wow, I didn't know they were THIS good..". So yeah, my brain 'burned in'? Probably. Drivers burned in? Definitely. smily_headphones1.gif

I never really believed in the concept of burn-in for headphones and speakers per se but rather that one simply acclimates to the different sound signature produced by a new pair of headphones or speakers. Well, that was up until now...

I have been completely god-smacked by these new JVC HA-FX750s I bought over a month ago. The detail and timbre has been monstrous (as well as, the bass) and the comfort... oh, the comfort.

Any way, after about forty hours of usage, I was listening one night and sat up shocked by some very noticeable and new details I was hearing in a song that I did not hear (nor have played) since the day I bought them. The only way I can explain it is that the FX750s must have cleared up and/or settled down since I have purchased them?!

I made a few more comparisons and discovered one other song with those very apparent extra details. Even more interesting is that I am listening at a volume lower than when I first purchased the FX750s and even from what I usually listen at with my SE535s!

As much as psychological acclimation (getting used to a certain sound) could still be an explanation for what I am experiencing with my JVC HA-FX750s it seems to me more likely there really has been a physical and audible change???

Now my Shure SE535LTS-Js they never changed in the way that they sound... the sound signature has remained exactly the same since Day One. Could it be that the FX750s are dynamic driven and the Shures are balanced armature driven?

By the way the two songs were Emmylou Harris's Goodbye (from the Wrecking Ball album) and Fritz Reiner's 1954 CSO version of Also sprach Zarathustra, Op. 30: Sunrise.

If you are certain that you got a good seal, then I guess you've been listening to bassy IEMs/headphones for a while. But FX series are "considered" to pretty bass heavy without overpowering the mids and highs

seems that you might be right to some extent. I recently made myself some foam tips out of ear plugs at work and I am indeed hearing some bass now. I was also listen to the new RHA T10i pretty exclusively back then as well. But the fx850 truly is the best sounding in ear in my collection. When paired with a fiio e11, its actually comically impressive, if that's even a thing :/ huge HUGE fan of JVC. Had tons of their in ear offering and these woddys are the bees knees
