Query: Microsoft LifeChat LX-3000 Headset

Microsoft LifeChat LX-3000 Headset arrived today - got it out of all that packaging - put the disk in and downloaded all that gobble gook - followed the instructions and no sound from the mike - sound from earphones is garbled - And now I see the price has dropped to $4.48.How do I get this headset to work?
