I just ordered three of these HTC headphone/usb splitters. (One for work, home, car, so I can charge the G1 and play Pandora at the same time.) http://www.ecrater.com/product.php?pid=4314395 I opened two of them and the standard 3.5 mm headphone jacks aren't working. Audio does not stop playing from the G1 speaker, and does not play from the headphones. My phone came with the standard headphone adapter. It's a long cord with a mic, 3.5mm jack, and a button to answer calls. Interestingly, if I plug that into the USB headphone jack on this device and plug in a pair of headphones it works. However, using an ordinary pair of headphones in the 3.5mm jack does not work at all. I tried two pair. Does anyone else own one of these things? Does it work for you?
