Monaural - relating to or having or hearing with only one ear.
A monaural corded headset is an example of classic design and functionality. They are used by receptionists (although many are switching to Wireless), call centres, contact centres and general office workers. All the headset manufacturers produce one-eared headsets with headbands.
This monaural corded headset traditionally plugs into your telephone via a small plastic RJ11 plug. This plug is connected to the bottom of your headset cable or a "pigtail" lead from your headset amplifier. Most of the time, it connects into the handset jack - you simply unplug the handset and replace it with the headset. However, be aware that you will probably need to keep the handset on your telephone to hold down the switch-hooks or the phone will be always busy and you wont get any calls. If this is the case, you will need to lift the handset to answer calls.
If you are lucky, you may be able to get your telephone technician to program your phone to use the "hands-free" feature or monitor button to answer calls. This is usually only available if you have a digital telephone.
Some telephones have a special headset jack. This may be an RJ11 or a small circular hole that takes a small 2.5mm plug. These phones also have a headset button for answering and hangup calls.
