FX3X update. They are now on 50 hours of burn and I might have sounded harsh on them but these are turning out to be very nice bassy earphones. The peaky upper mids are still there but are no way ear piercing or too harsh now. The overall sound is starting to settle but again I am not quite fully yet done with burn. I do like how they sound and getting better with time and use.
I can now say for guys that want a full sounding bassy musical earphone the FX3X is a good value at their price. Now the issue now is these have some very stiff competition for your hard earned cash at their price point. I would still recommend the CKM500 for guys that want more than just big bass. But for guys that put bass first as a requirement with a clean sound the FX3X does do one up on the FX101. But just barely..The value is not even remotely close to the FX101 but the FX3X are turning out to be a solid bassy earphone..Also with the new FXD80 being released within a few days. I have a feeling these FX3X will be a overlooked. Oh well onward and upward!
SO as of now I will rate the XX series as such.
The FX3X>= FX101>FX1X
