    So reading that, I am thinking same dynamic as the F9 but the pro substitutes a single Knowles TWFK Dual BA package for the 2 distinct BA drivers used in the original F9. So I am guessing the bass and sub-bass should retain the same signature from the previous model while the mids and treble should be improved. Maybe with less of a spike around 7kHz than what the F9 presented. That would be a welcome thing in my opinion as that spike fit perfectly in a range that made the F9 unusable for me.

    Hopefully someone will soon post the response graph that will clearly show how much the pro improves from F9. Although most would want to know what that means to their ears.

    I'm surprised with so many people loving F9, that the F9 pro is not getting the recognition. And F9 pro is making an improvement over the F9.

    Edit: It's like a social networking thing, all of the interests are posted on a different thread. It's just this thread is different. I'm pretty sure there is a way to investigate why it is different, but powers that be want to keep this ability to themselves.

    Between v-tie and other putty or diy bonding agent, do you think a right angle mmcx adapter can be made; so that a cable up earphone such as this can be worn cable down. Cause I saw naked mmcx connectors being sold on ali.

    So far a lot of enthusiasm for the F9 pro bass but only concerns about the treble being same or different than F9. It is really not possible to be certain with only a couple of people so far getting theirs in the international market.
  15. SomeGuyDude
    Shouldn't the treble be precisely what IS changed, since it's different BAs for the Pro?
