Make Music Sound Better with iPhone connected to USB port
When I connected my iPhone 5 to the USB port and selected the "Audio Source" of "iPod" the sound was very tinny and not very full or rich. I tried the change to the DSP/AMP settings in the "Developers Menu" but it didn't help at all. I then came across some setting on the iPhone itself that made my iTunes music sound so much better when connected to the USB port.
* Open the Settings app and then head to “Music”
* Flip “Sound Check” to ON
* Next, tap on “EQ”, and then choose an equalizer setting most relevant to the majority of your music collection (Rock, R&B, and Pop are all decent choices for most music varieties)
Very easy to do and made a huge difference for me.
