Stereo?

Since all of you have raised this issue, let me make it clear that I DID, in fact, explore the entire signal path. I took a normal pair of 2.5mm cellphone headphones and plugged them into the HTC-supplied adapter. The result was that only the right channel worked. So here's the score:

Mogul to HTCadapter to adapter to cable to car stereo - right channel only
Mogul to HTCadapter to adapter to 3.5mm headphones - right channel only
Mogul to HTCadapter to Seidio 2.5mm headphones - right channel only
Mogul to HTC-supplied headphones - full stereo.

That's why I conclude that the HTC-supplied adapter is defective.

To answer Budney's question, my 2.5 to 3.5 adapter worked fine with my Treo, and to answer Dishe's remark, it DID come from Radio Shack. I also have one from TreoCentral, which I'd try if I could just find the darn thing. <g>

Destructor, thanks for the product pointer. It would be nice to have an adapter that goes straight to the 3.5mm socket. I'll still bug Sprint about replacing the HTC one.

Edit: I just found my TreoCentral 2.5 to 3.5 adapter and tested it. Same result, right channel only.
