Hey Samsung i730 users,
Not trying to spam, I just found an accessory that works! I purchased this item and it works great with regular headphones while using the Windows Media Player- MP3 function.
I turn off the phone feature and it works great. Cheap and worth every penny

I had one and it didn't deliver stereo. Are you sure yours does?
