I decided to review the FX500 filter removal in realtime.
The JVC FX500 is a pretty decent IEM.
There is an important variable involved in reviewing IEM's which I call... acclimatization.
It's pretty simple, you're used to a certain kind of weather, you move to a different country, you complain - yet no one else does.
In order to truly appreciate the qualities of an IEM, you have to be "in the zone" with it, well, that took a while for me with the FX500, since I was hit with a dose of expectation error, and difficult acclimatization.
The reviews (except 1) made me expect a very clear and spacious IEM with unparalleled timbre, that just didn't happen.
Compared to the the spacious Sony EX series, everything sounds so narrow and confined, if you're not "in the zone" with it, it doesn't sound like much improvement over a standard Apple earbud, which is exactly what the amazon.jp review said it sounded like, and they received iirc 17 "this was helpful" amazon clicks.
So anyway, it is an interesting IEM, if you can get past the "funnel" sound, and the resonance, I really don't think the brass eliminates resonance, it sounds like it... contorts it, there is a "brass resonance" of some kind, which makes certain vocals and notes sound 'hard', like an iron type of sound.
Hidden behind the resonance however, is a very capable driver, which changes quite a lot from source to source, it is receptive to quality. If you want to 'listen' to the quality of electrical components like D/A, this IEM will help. If you just want to use it with a smartphone and that's it, and you enjoy spaciousness and clarity, this isn't it.
Anyway, someone did a "filter removal mod" and reported good results, which is what I'm going to try now.
**half an hour later**
I can't remove these filters yet, srsly.
Are you supposed to send a robot spider down the nozzle or what?
