I just received my loaner sample for review, thanks go out to @CEE TEE for including me on the preview list. I’ve been a big fan of JVC woodies going all the way back to the FX500, JVC’s first woodie. The FDX1 is a different sounding beast compared to the JVC HA-FW01, so after a full burn-in of 100 hours, I’ll report back my observations with a link to my review. @james444 is right about the speed/clarity being exceptional. I did find the final E series tips worked better for me in terms of seal, and they helped a bit with taming the bright nature of the standard nozzle.
