COTS (cheap off the shelf) wireless telephones with headset jacks.
A quick hack of the base station gives you access to separate
tx/rx voice paths. Radio Shack & Wal Mart have them.

Wireless intercoms as used by television and theater productions.
Professional wireless microphones with in ear monitor.
Pricey but turnkey.

Have you tried using google yet?
