Motorola ROKR E2
Only drives headphones?? Can this be true?!?!
To our surprise and horror, the Rokr punted when asked to drive a car- or home-stereo's line-in jack, falling back on its tiny, tinny built-in speakerphone speaker after about half a second. This seems like a serious failing, since every other portable stereo device we've ever used could easily be plugged ...
What stereo systems have you plugged your phone into? I have some Altec Lansing computer speakers and it doesn't work with those, and I have a Sony home theater receiver with a RCA-to-3.5mm cable that I bought and it doesn't work with that either. My old 64 MB flash MP3 player I bought years ago works with both.
Not elegant, but it works. Of course the mic doesn't work since the y-cable doesn't have 4 contacts, only 3.
