On Ebay, I bought a cell phone with FM radio, that gets the radio from
local stations, not from cell phone data, and after I bought it, I
found the manual online, which says that the radio antenna is the wire
to the earphones.

But the phone didn't come with the factory earphones.

Mostly I want to listen to 88.1 Mhz FM, and if possile 88.5, and
90.1frequencies.

For antenna purposes and those frequencies, are there any differences
from one headset to another?

Does the thickness of the copper wire matter?

Factory headphones may be impossible to get. without buying a second
phone. Should I try to find out how long the wire is on factory
earphones and get a headset with the same length?


Any set of headphones should work fine.

I have a Nokia with FM and the correct headset but always use it with
the earphones from my MP3 player (I don't use the phone hands free, so
don't need the microphone).

The screen (US: shield) of the cable is used as the aerial/antenna but
most (if not all) earphones use screened cable.

I don't think the length is going to be of any real consequence, though
a quarter wave whip @ 90MHz is ~80cm (~31 inches) if you want to try and
find a match!
