You're probably right...unfortunately for my purposes, my phone is my one and only source with these IEMs; its much more likely I'll move to a different IEM than a new phone (although admittedly I'm pretty stoked about the G3).
Right now I'm just hearing the FA4 as a mix between the UE900 and UM3X: the presentation is more exciting, but the tonality is so far off that it feels a bit painful. The timbre feels really inconsistent: some voices, especially softer ones, sound great, while other, more emphatically sung vocals, especially female, sound really muffled and artificial. I think is is a tesult of the mids and lower treble being uneven. It's the same beef I take with most of the IEMs I've ever owned: there's a dip around 5khz that just sucks the life away from the music. I've tried EQing to compensate but it just makes it screwier.
I saw this in the FA4's graph but ignored it due to all of the comparisons people had drawn to the TF10. NEVER AGAIN! From here on out I trust graphs>people's opinions.
