KZ EDX Pro x KZ EDC Pro what is better?
I have both, just received my EDCs and compared them to the EDXs, which have been my go to for on the street listening.
It wasn't exactly a scientific comparison, listened to one, unplugged, put the other one on, plugged in, a few seconds pause in between, rinse an repeat.
I have to say subjectively I favor the EDCs. They seemed to have more bass - in spite of the useful graph provided by brydon10 - a little more air, but silkier, more subdued highs. Not that the EDXs are harsh, but they are a bit spikier, a bit more papery sounding. Also a little more low mids for the EDC - again, somewhat in contrast with the graph. Maybe that dip between 400-1500 Hz gives that subjective impression. The output of the EDCs seems to be slightly lower overall.
On the whole I hear more detail on the EDCs, and they sound a little more natural - the EDXs sound a little flatter - not as in transparent, but as in without relief - and papery. It's a very small difference though, don't think it's gonna be a significantly different experience. All in all, i think the EDCs have become my new go to.
