Hi,
How can I take a standard pair of ear buds, cut one off
and use the other one as a mono signal that combines
both channels [for use in one ear].

I've tried adaptors, but the mono plugs that fit into the
adaptors have a terrible sound.

I stripped one inexpensive pair of buds and saw that there
were two wires in each casing, making a total of four.
One of each pair were the same color, but combining
those [twisting together] and the other two wires
did not produce a mono signal.

Is there another way to do this?

Thanks.

Borrow the combining idea he
http://www.epanorama.net/circuits/linesum.html

INPUT 1 -------\/\/\/\---+
---+ R1 10K +------------ OUTPUT
| | +----
INPUT 2 -------\/\/\/\---+ |
---+ R2 10K |
| (shields) |
+---------------------+

Chan ge the circuit so that you use 33 ohm resistors
istead of 10 kohm resistors.
The Input 1 and Input 2 are in 3.5 mm stereo plug
the tip and ring.
This shoudl give you mono output that can drive
the single headphone you want to use.
