Since you are using a BT signal, your problem partially lies in there. Pandora and such generally have an emphasis on highs and lows, with a gap in the midrange. The infinities are generally a similar animal, they lack in the midrange area but will make you cry on the highs and do decently on midbass. A different set of comps could cure this, but attenuating the midbass and highs on songs that you'd like to have more midrange in would also help your cause.
