Head Sets

You can’t compromise when it comes to call quality.

Why are there so many different types of headsets, amplifiers and cable configurations?
Apart from the obvious reason of catering for personal preferences, there are also some technical reasons for the many different products:

Headset cables have four wires – two for the microphone (transmit) and two for the speaker (receive). These wires have to be in the correct places on the connector that plugs into the phone, otherwise, the headset cannot work. Unfortunately, there is no set standard so not everyone wires their telephones in this way.

Some telephones cannot boost the transmit (speech) level of the headset enough for callers to be able to hear the headset user clearly. In these instances, an amplifier or a headset with a high-gain microphone has to be used.

Speech Circuits
Telephones also have different types of speech circuits. Most telephone instruments nowadays use an Electret microphone. A few use carbon type microphones and some of the older instruments use a dynamic type microphone.

It is vitally important that the headset’s microphone type is compatible with the telephone’s speech circuit otherwise callers won’t be able to hear the headset user.

The majority of today’s headsets use an Electret microphone, so they’ll work on most modern instruments. Some amplifiers allow one to match a headset’s Electret microphone to a carbon-type instrument.
