I have a MTS2000 that I want to use with a ear phone so I can monitor while in meetings and such without disturbing everyone in the room.

I purchased a external audio adapter from ebay but whenever I plug a standard ear phone into the adapter I get a constant tone through the ear piece except when it receives radio transmissions. The plug for the ear phone fits loosely in the jack and if I move it around it the radio transmits.

My question is, do I need a ear phone made by motorola or do I have a bad adapter.

You need a special earphone to use with the Jedi audio adaptor. If not it keys the transmitter or sets a constant tone.
You could cut the center conductor on the cord to the earphone and add a 10uf capacitor with the "+" side twards the radio connector/plug's tip.
Also the 3.5mm threaded plug on the earphone must be a three conductor and the earphone hooks to the "tip" and ground, no connection the the other "ring" contact.

Is this ear phone available only from Motorola or can it be found else where.

I have several alternate sources for earphones. It is easer to modify the cable on one than pay the Motorola price,,, about thirty five dollars or so.
