Alright I am not gonna bother making a review for the FW02...it has more bass quantity than the Tanchjim Hana and similar treble quantity...but it is sharper and grainier at the same time....

Grade C.
seems like the rise from 2.5k - 5k is the spot, they rise much more than B2 in that region

If it is a JVC XX02 model than you can bet the cable is a thing they may have skimped on as less work/less $$ spent than reworking the earphone innards. Should have potential for improvement and esp. removing the grain or any peaks the treble may have.
I did change the cable to the Faaeal litz copper cable.

Gonna return it to amazon. Being able to return it like that so quickly and without issues is nice.

Okay grain over more than one cable and returning quick. Did you give them enough hours. I don't subscribe to the hundreds of hours stuff but as an owner of dozens of JVC earphones they should be worked out for a hundred to be sure. Though some grain never does go away. :)

It was a second hand unit. So dont know how long they used it for. But at this cost for that kind of treble is not worth it for me and I rather use the tanchjim Hana over it...

I use this FX850 "j444 mod" version 2 mod as an example for some of my earbuds that have problem with bass quality

It is the treble that is bad on the FW02, not the bass. That mod seems like it reduces the bass quantity so that would make the treble even worse.

On the FX-850 you can significantly reduce the bass by simply taping the back of the shells but then you're left with very aggressive upper mids (which could be tamed by a micropore mod on the nozzle and make them overall relatively balanced I guess).

Hey guys,I bought a BA5 recently after waiting 4 months for TRN to iron out the QC problems. The Ali shop guy told me it's a new production piece but sadly it has the same issues. Volume goes low on one side, certain drivers stop working with moisture issue if am right. Some days it work and when they do, thers nothing better but you never know. They can go on a strike anytime. I love the tuning but hate TRN's QC. First my left had issues which got fixed by itself overnight, then it was the right which also got fixed by itself. Yesterday there was a slight distortion from the left side. Since I love the sound soo much, I choose to live with it and keep it with silicon packets whenever they go on a strike but this distortion is something new that I've never heard about. Anyone else with similar issue? Is that also related with moisture problem? Any suggestions would be highly appreciated. Thanks!

Considering your meh rating of the Spring 2, it would've been quite a coincidence, if you had chosen to use a guillotine board as your backdrop.
Not saying they are meh, they are average for me. Pretty competent but doesn't have that uniqueness that'll make them stand out from their competitors.

(it is green and not blue like in the pictures....) (and the box states it is the black version not the green, hopefully only my package is like this as I did pick the green version)

Why is it that its almost always the cheap iems that fits me really good....even the stock tips fits me very good......
