USB HEADPHONES ANYONE USING USB ON THE JORNADA 820

I'M growing fond of my new to me HP JORNADA 820(less the a week), now how to listen to it without the speaker.There are USB headphones out there wonder if they would work wit the 820????does the USB port supply enough power.My problem is my BUY<TRY and Return profile is wearing kinda of thin around these part's......

I cannot say I know of this product, however I am going to put my neck on the line here and say they would need a driver to 'disconnect' the speaker and then send the sound through the USB port. Unless you can find a specific CE 2.11 driver, I do not beleive you have any chance here.
