I have also seen this problem. I have a pair of headphones that are not terribly efficient, so I bought a "Boostaroo" (sp?) amplifier. I was very disappointed to find out that when I did this, the noise on the output of the Nokia 800 was sufficient make the experience unpleasant. I also found the same when I tried to run the N800 thru my car stereo. There seems to be a lot of background noise in the output of the N800 which becomes objectionable with just a little amplification. My guess is that it's a design problem. If anyone comes up with a work-around, please let me know. Gary Walborn gwalborn at gmail.com
