Do you want Mic as well? If you look at the Nokia provided earbud you see:

Code:
0=|==|==|==={{{{    -- Headphone Plug
L   R  M Gnd        -- N800 jack
If you plug in a Mono earplug you'd have
Code:
0=|========={{{{    -- Headphone Plug
L   R  M Gnd        -- N800 jack
The right signal and microphone would all be grounded. Thus, with a Mono connector, you'd be left with left channel only. However, I think the N800 could detect that the right channel is grounded and do software mixing on the left channel. I know some devices do this, but I don't know enough about audio to know if that's the standard behavior.

If you want to ensure the audio is mixed, you'd have to use a 3 or 4 conductor jack and then splice the L and R signal wires together. Radio Shack's 274-374 adapter does that for you so you don't need to cut wires. You can then use a mono earplug or take a stereo earplug and lop off the right speaker.
