iPhone equalizer

...boost the treble and reduce the bass. Works well on the Mac and it is too bad that I can not get this to work on the iPhone.

It is too bad that I can not just carry my Mac around ...

Mike, just wanted to revive an old thread to send a quick FYI. You don't have to carry around your Mac .
The "Late Night" setting for the iPhone/iOS Music equalizer (Settings > Music > EQ > Late Night) is actually the only one that DOES work on audio output aside from just Music. It's a dynamic range compressing function that mostly levels vol, but I've found it does help a bit with bass reduction. It's not super dramatic, but it does help.
Best bet is good headphones, as it sounds like you've discovered. I've become more and more careful about checking the sound profile on headphones before buying, because there's a trend toward more bass = more buyers (mainly due to music genre popularity).

Thank you for that information. I had no idea that there was any way to get the iPhone equalizer to adjust the sound other than the regular equalizer, and that did not work for audible books.

I was so concerned about my ability to adjust the highs and lows that I replaced my Apple phone with an android phone some time ago. It does not have this restriction and, interestingly enough, the android Audible app provides more control over playback than the IOS version. However my wife still has an iPhone and I will try this on her phone. Thanks for updating this thread and letting me know.
