does the audio quality among i devices differ? im listening to my new shuffle and i think it sounds considerably better than my iPhone 3G, im using the in ear buds with remote on both, and the shuffle has better base, and just stronger sound. I have 320kbps audio synced the both also, so it just must be the way they handle audio, ive also heard the 5.5G ipod video has the best sound due to its wolfson audio processor.
