if you were only getting sound in one ear and are now getting sound in both by using a piece of tin foil, i would imagine its bridging the connection far enough up the adapter plug to let the full contact of your headphone plug be touched.
so basically you have dual mono. it's just now able to send the same sound to both contacts of your headphone plug while in the modified adapter so that both ear pieces are audible.
UNLESS the adapter is indeed made for and indicates on the packaging that its a stereo 2.5-->3.5 adapter. in which case i dont know why it wasnt working in the first place as the pearl is stereo. and with the tin foil its now probably crossing signals and youre still getting dual mono when you SHOULD be getting stereo
