This is a Freelinc free mic 200 that also comes with a ear bud and desktop charger that were both extra. These items were well over $325. It works for XTS2500,and XTS5000 radios. It may also work with others, please check there website. It works great I'm just not able to use it at my dept. no personal equipment is allowed. Please email me with any other question and I will try to answer.
