I believe most people don't really care about audio options and perfectly fine with Apple's only toe dipping into prebuilt sound settings that are incorrectly filed under equalizer. I myself find these options rather abhorrent and unfortunately, there really aren't any good options out there. Sure there are some apps that allow multi-band EQ however they sound forced and aren't accurate because Apple doesn't allow these changes in the system. I really, really wish Apple would some day at the very least include a true five-band equalizer if not a ten-band equalizer. Do Apple's current audio options bother anyone else or is it just me?
