I just picked up the XBA-A3, which is essentially a more refined version of the H3 and similar to the past Sony IEM flagship the XBA-Z5.
Both A3 and H3 are going to have exaggerated low end. They are very good if you are fine with this. Personally, I prefer something with a flatter tuning. Etymotic HF5 or ER4 series, older Sony MDR-7550 / mdr-ex800st. Vsonic gr07.
Maybe wait until you get your 1000x to see if you are missing anything sonically or from a functionality standpoint.
