The solution is a simple cable, that you should be able to get for $5 or less. Ask for a cable with male 3.5mm (1/8") plugs at both ends. Connect one end to the MP3, and the other to the line in on your computer. Now the sound comes from the computer speakers, and you don't need the headphones
An alternative solution is to mount the MP3 player as a disk drive, if it is capable of doing that. Then you can use your media player of choice and just browse to your MP3 player. No need for a cable.
I am doing some research on buying my 1st mp3 player and have narrowed the search down to (1) Sansa e260, iRiver Clix2, or the Zune. I want to be able to listen to it at my desk, but didn't know if I would need to buy a speaker dock, or if I could listen to music through my computer speakers.
Probably a dumb question....but I can't seem to find an answer anywhere.
