Ok, we've got 2 Moment's at the moment... I was noticing how much quieter the headphone out was on mine than my old TP2 was. I read a few posts online that said they had the same 'issue' and it wasn't so bad, just softer. So, I lived with it. Then we went driving the other day and my wife plugged her Moment in to my stereo and BOOOM! It was just as loud as the radio... about 2x the volume that mine was... Is there a chance that there are defective earphone jacks in some of the Moments or do you think there's a software glitch is some that are creating a volume limiter? Any thoughts?
