A few points to consider.
Monaural (headset): One earpiece
Binaural (headset): Two earpieces
Full-Duplex:
Communication can be Sent AND Received simultaneously. Communication in both directions simultaneously. Think standard telephone (i.e. two-way bridge in traffic)
Half-Duplex:
Communication can be Sent OR Received but not simultaneously. Communication can occur in both directions, but not simultaneously. Think UHF (i.e. One-lane bridge in traffic).
VOX: Voice Activated. Can be either Half-Duplex or Full Duplex.
example: Telephone= Full Duplex
Speakerphone = Half-Duplex (ever wonder why sometimes two people on a speaker phones are talking over each other all the time?)
PTT:
Push To Talk/Press-To-Transmit: These are Half-Duplex communication devices which will stop receiving signal and begin broadcasting when the button is pushed. VHF, CB, SSB are good examples of Half-Duplex/PTT devices.
